Transcript
- 0:10SPEAKER_01: Hello, you're outdoors with the Yorkshire Wildlife Trust.
- 0:13SPEAKER_01: From wild swimming to dog walking, birdwatching to rock balling, we're going outside to try new things and chat about why those things matter.
- 0:22SPEAKER_01: I'm your host, Sassy, from Yorkshire Wildlife Trust, and I'll be exploring our local landscapes with the people who love it.
- 0:31SPEAKER_01: This week I join my colleague Anna Powie at Filey on the Yorkshire Coast.
- 0:36SPEAKER_01: Anna is a marine project manager and hosts a range of events regularly through the year where volunteers can help collect marine data and protect our stores.
- 0:44SPEAKER_01: Today, Anna is hosting a store search survey.
- 0:48SPEAKER_01: Volunteers will rock all together, documenting and tracking what they find.
- 0:51SPEAKER_01: I've come to the beach early and spent the morning having breakfast on the sand.
- 0:55SPEAKER_01: It's a beautiful and blustering day, and as I walk up the hill, I can see Anna.
- 0:59SPEAKER_01: I've got my hefty walking boots on, ready to explore Yorkshire's coastline and find some brilliant marine life.
- 1:05SPEAKER_01: You alright?
- 1:06SPEAKER_01: Yeah, I came really early.
- 1:08SPEAKER_01: I've gone for a swim.
- 1:10SPEAKER_01: Yeah, yeah.
- 1:13SPEAKER_01: It was kind of cold, but and the tide was really in at first, so I just waited and then it went out and there was sand and I saw some other people going and I was like, okay, I'm just gonna go.
- 1:22SPEAKER_01: It's actually like really bearable.
- 1:24SPEAKER_03: Okay, I might actually put my wallies on.
- 1:26SPEAKER_01: Yeah, go do it.
- 1:27SPEAKER_01: How many have you got for the Biabler today?
- 1:30SPEAKER_05: I think we're probably on like 12 or 11.
- 1:35SPEAKER_05: Whoa, that's it.
- 1:35SPEAKER_05: Yeah, we did pretty good.
- 1:36SPEAKER_05: Yeah, like the thing is because we've kind of built it up over the last couple of years, yeah.
- 1:41SPEAKER_05: It's pretty like we've got a constant kind of group of regular people that will come to most dates.
- 1:48SPEAKER_05: And I think because we put the um we do the dates all in advance, yeah, so they can put them in the calendars and kind of make sure they're free for it, so it's brilliant.
- 1:56SPEAKER_05: So that's what I've done as well.
- 1:57SPEAKER_01: I'm gonna come to the Runswick one in August.
- 2:00SPEAKER_05: Exactly, it just means because life gets so busy, doesn't it?
- 2:03SPEAKER_05: Your calendar goes insane, yeah.
- 2:05SPEAKER_05: And so I just I can I don't think I can do it any other way.
- 2:08SPEAKER_05: No.
- 2:08SPEAKER_05: Just got to put them in, get them in, dedicate them, and that's it.
- 2:12SPEAKER_05: Like where was the last one that you did?
- 2:13SPEAKER_05: Was it um where was it?
- 2:15SPEAKER_05: Good question.
- 2:16SPEAKER_05: Well, I was helping with a different project at Sand's End on Wednesday, um, and I think the last one we did was here, but we were doing a quadrat, which is a lot more kind of looking at a smaller area at the species that you find.
- 2:32SPEAKER_05: Um which is good because it makes you zone in.
- 2:35SPEAKER_05: Yeah, rather than just like yeah, yeah, yeah.
- 2:37SPEAKER_05: So today is going to be a lot of just finding as much as possible wherever we can.
- 2:43SPEAKER_05: Um so it's it's lovely to have the different types of surveys.
- 2:46SPEAKER_05: Yeah, yeah.
- 2:47SPEAKER_02: Um did you find anything cool last time?
- 2:50SPEAKER_02: Oh, good question, you're testing my memory.
- 2:53SPEAKER_05: Um let me have a think.
- 2:54SPEAKER_05: So on Wednesday we definitely found some cool stuff, and it was a shore I'd never been to on at Sand's End.
- 3:00SPEAKER_05: So we we found uh sea urchins, which are those big pink ones, um, and they've got amazing tube feet that were coming out of the water.
- 3:08SPEAKER_05: Found a big old lobster, which is always lovely, yeah.
- 3:10SPEAKER_05: It's cool.
- 3:11SPEAKER_05: So you just never know what you're gonna find, which I think is one of the beauties of rock pooling, it's just it's different every single time.
- 3:18SPEAKER_05: Even if you go to the same shore, the same section, there'll be different things throughout the year, so it's just amazing in that sense.
- 3:25SPEAKER_01: Yeah, really cool.
- 3:26SPEAKER_01: Do you have a favourite um beach or coast?
- 3:30SPEAKER_05: To be honest, Filey Brig today, like I think that is one of the most interesting shores you can go on because it's that kind of that peninsula of land where you've got a sheltered and an exposed side.
- 3:44SPEAKER_05: Yeah, the wildlife kind of on either side is completely different, and it's so fascinating looking at the two.
- 3:50SPEAKER_05: Um, but also it is just brilliant rock pooling generally.
- 3:53SPEAKER_05: Yeah, fantastic.
- 3:54SPEAKER_05: And for me, I'm biased because I I live nearby.
- 3:57SPEAKER_05: Yes.
- 3:57SPEAKER_05: I can pop here whenever.
- 3:59SPEAKER_05: But I also um I grew up in Wales uh in Cardiff.
- 4:03SPEAKER_05: Yeah, and I was very, you know, used to go to the Gower a lot, the Gower Peninsula, and there's amazing shores and and beaches there, so that that's also close to my heart as well.
- 4:12SPEAKER_01: Oh that is nice.
- 4:14SPEAKER_01: Talk to me about like the different variations of sessions that you do runs, beach cleans, we're doing rock pooling, you do shore search surveys.
- 4:23SPEAKER_01: Is there anything else in that mix?
- 4:25SPEAKER_05: Absolutely, and so loads of citizen science opportunities because we're very wary that you know we need eyes and ears and we want local people to be involved and engage with the marine environment.
- 4:36SPEAKER_05: Uh so we also do sea watches looking for whales and dolphins along our coastline.
- 4:40SPEAKER_05: Oh, I bet they're popular.
- 4:41SPEAKER_05: Absolutely.
- 4:43SPEAKER_05: Although it can be frustrating if you don't see any of that is as important data as any.
- 4:48SPEAKER_05: Really yeah.
- 4:49SPEAKER_05: Um, and and that's something that I think strikes me is often people don't realise that we do have whales and dolphins along our coastline, and they're you know the sightings are increasing and increasing every year, and so it is worth kind of looking at and monitoring, especially with things like climate change and changes in distribution is going to be more important than ever.
- 5:08SPEAKER_05: It's great because my my parents were visiting this weekend.
- 5:11SPEAKER_05: Oh yeah, and you know where people come to visit, and then you end up doing all the things that are on your doorstep, but you just don't do because you live there.
- 5:18SPEAKER_05: So we went on the Yorkshire Bell from Bridlington and saw all the cliffs and the seabirds, and it was so brilliant.
- 5:24SPEAKER_05: That is really nice.
- 5:25SPEAKER_05: Seeing the cliffs from that different kind of viewpoint was is I was I was blown away basically, and like I need to go again because I I just never get.
- 5:33SPEAKER_01: Yeah, I think that's something quite nice, like because I'm from Norfolk, so I spend a lot of time on the coast down there, but like bringing your family and friends to like the new parts of landscapes that you like to visit and you live in.
- 5:45SPEAKER_01: Like um, I've lived in Leeds for about six or seven years now, and then my parents came up a few years ago and we went to Whitby and they loved it, but it's such a different coastline to the to the Norfolk coast, and uh that that was really special, like getting to explore that place with them, definitely.
- 6:02SPEAKER_01: Yeah, so this is pretty seaweedy.
- 6:05SPEAKER_01: I mean the tide is going out.
- 6:06SPEAKER_01: When I first arrived, it was so in.
- 6:08SPEAKER_01: Yeah, I could like barely actually get onto the beach.
- 6:11SPEAKER_05: Absolutely.
- 6:11SPEAKER_01: It always surprises me how quickly it does go out there, because now there's loads of sand.
- 6:15SPEAKER_05: Absolutely, and that's something that people do need to be mindful of.
- 6:19SPEAKER_05: The sea's amazing, but it can also be dangerous.
- 6:21SPEAKER_05: So you've just got to be really careful with water safety, making sure you're checking tides, making sure you're just really aware of where you are.
- 6:28SPEAKER_05: Um, because you can get caught out.
- 6:30SPEAKER_05: So here, you know, if you were at the brig um on the end and the tide's gone in, you're gonna have to be clambering up the top of the museum.
- 6:38SPEAKER_01: Really dangerous.
- 6:39SPEAKER_01: From like a rock pooling perspective, then what are we looking for when we're looking at it?
- 6:43SPEAKER_01: So, right now there's quite a lot of seaweed, there's bits of rocks everywhere, and the tide's kind of coming in and out.
- 6:48SPEAKER_01: Like, what is a good rock pool that we're like, that's what we're gonna go and aim for and look at?
- 6:52SPEAKER_05: Well, so it's really interesting because on the shore you have something called zonation, and you can basically tell which zone, whether you're at the top of the shore, the middle of the shore, or the low shore, depending on the species that you can see.
- 7:04SPEAKER_05: So, all of this seaweed here kind of uh tells us that we're in the upper shore, so right at the top, so we can see a lot of the what we call racks, which are a group of seaweeds, um, and so I can see some spiral rack, which is very much an indicator of an upper shore.
- 7:20SPEAKER_05: Um but as the tide drops, it'll start to uncover all of those rock balls and those different species in those different zones.
- 7:28SPEAKER_05: Um but I think for me I really like having you know an accessible shore, but some rocks that you can turn over safely.
- 7:35SPEAKER_05: Nice.
- 7:36SPEAKER_05: Don't be uh trying any boulders, no, but looking at kind of what's what's underneath, and and I think that's a really good way to start.
- 7:43SPEAKER_01: Okay, cool.
- 7:44SPEAKER_05: Do you have like any good advice for like actual lifting of rocks?
- 7:48SPEAKER_05: I think just take it really slow.
- 7:50SPEAKER_05: Yeah.
- 7:50SPEAKER_05: Because obviously there's gonna be things potentially underneath.
- 7:53SPEAKER_05: Uh-huh.
- 7:53SPEAKER_05: Take it really slow and just no sudden movements and making sure that everything is put back exactly where you found it.
- 8:02SPEAKER_05: Often people forget that they might turn over a rock and not put it back, and that means loads of those animals which were sheltering from you know the sun and all sorts might then dry out.
- 8:13SPEAKER_05: So we want to have as little impact on the shore as possible.
- 8:16SPEAKER_05: Yeah.
- 8:17SPEAKER_01: Yeah, that is good to remember as well because I feel like part of that mindfulness is also like caring for the environment as well.
- 8:23SPEAKER_01: I feel like that's a good step.
- 8:24SPEAKER_05: I know that is a step though.
- 8:25SPEAKER_05: Just be careful with your footing.
- 8:27SPEAKER_05: Yeah, absolutely.
- 8:28SPEAKER_05: We're we're going into its space.
- 8:30SPEAKER_05: Yeah.
- 8:30SPEAKER_05: We are, you know, almost an imposter in that environment.
- 8:34SPEAKER_05: And so we absolutely need to try and have as little impact as possible.
- 8:38SPEAKER_05: Um, and people might say, you know, we shouldn't rock pool, we shouldn't kind of disturb it, but we feel like the um disturbance we we minimise as much as possible, but also the data it gives us is really really valuable.
- 8:51SPEAKER_05: Yeah.
- 8:51SPEAKER_05: And what sort of data like are you hoping to see when you are rock pooling?
- 8:56SPEAKER_05: For me, it is that long-term data set, which is a real challenge to collect because um funders don't often fund that.
- 9:04SPEAKER_05: So we we try and kind of continue it no matter what on the side of our desk.
- 9:07SPEAKER_05: Yeah.
- 9:08SPEAKER_05: Um, but what we want to be understanding is trends and changes in distribution and species over years.
- 9:15SPEAKER_05: And like I say, especially now with climate change, pollution, you know, the sea is becoming a really busy place.
- 9:22SPEAKER_05: Yeah, um, it's important now more than ever that we do have those records.
- 9:26SPEAKER_02: Yeah.
- 9:26SPEAKER_05: Um, because if not, you might have shifting baselines, you might kind of now come rock pooling, not really find any starfish and think that's the norm.
- 9:34SPEAKER_05: But a few years ago, they anecdotally there were a lot more.
- 9:39SPEAKER_05: Okay.
- 9:39SPEAKER_05: But without that data, we can't say that for definite or prove that for definite.
- 9:44SPEAKER_05: Yeah.
- 9:44SPEAKER_01: Are there any species that you're like there's like a noticeable decline and then a noticeable incline as well?
- 9:53SPEAKER_01: Incline's a hard one.
- 9:54SPEAKER_01: Yeah.
- 9:55SPEAKER_01: I can't think of anything off the top of my head.
- 9:57SPEAKER_01: Oh, that's sad.
- 9:59SPEAKER_05: And I think there might well be and there will be.
- 10:02SPEAKER_05: Um, but it's just so hard to monitor that in a meaningful way to understand what actually is going on.
- 10:09SPEAKER_05: Anecdotally, we have seen declines.
- 10:11SPEAKER_05: So, like I say, things like starfish, you'll talk to people and they'll say when they were kids rock pooling, they found starfish everywhere.
- 10:18SPEAKER_05: You know, it's it's a pretty, you know, pretty rare thing nowadays for us to actually find, you know, a common starfish rock pooling.
- 10:25SPEAKER_04: Yeah.
- 10:25SPEAKER_05: Um, and another thing is um we get a lot of uh something called mussel spat, which are young mussels attaching.
- 10:33SPEAKER_05: We'll we'll find thousands on this shore here at Viley Brig, but there are no adult established mussel beds that we know of.
- 10:40SPEAKER_05: Okay.
- 10:41SPEAKER_05: So there seems to be something stopping them from thriving on the coastline.
- 10:45SPEAKER_05: Right.
- 10:46SPEAKER_05: And that's something we're really interested in looking into with partners like the University of Hull.
- 10:50SPEAKER_05: So it's it's really interesting, and something I want to be monitoring more and more is with kind of increasing temperatures, those shifts in marine invasive and non-native species.
- 11:02SPEAKER_05: Yeah.
- 11:02SPEAKER_05: We are seeing that at the moment.
- 11:04SPEAKER_05: Really, yeah.
- 11:05SPEAKER_05: So last year we found a um something called a slip a limpet on this shoreline, and it's the furthest north we think we've ever found.
- 11:15SPEAKER_05: Wow, really?
- 11:16SPEAKER_05: Yeah.
- 11:16SPEAKER_02: Wow.
- 11:17SPEAKER_05: So it's really, really important that we've got eyes looking out kind of regularly and reporting that so that we can really understand how quickly that species is moving up.
- 11:26SPEAKER_02: Yeah.
- 11:27SPEAKER_01: Well, we talk a lot about like invasive species at the truss, like quite a lot, particularly when you think about like crayfish and stuff.
- 11:34SPEAKER_01: But I'd never really thought about it like on the coastline as well.
- 11:37SPEAKER_05: Yeah, it's a thing, definitely.
- 11:39SPEAKER_05: And especially with the brilliant projects we have, like the Wilder Humba Marine Restoration Project down at Spurn Point, and where we're restoring uh seagrass and native oysters.
- 11:50SPEAKER_05: Um, that is going to be the first point that these invasives enter Yorkshire.
- 11:55SPEAKER_05: Yeah.
- 11:56SPEAKER_05: So it's really important that we are monitoring it because they could impact those restoration projects.
- 12:02SPEAKER_05: Um, but also we need to think about, and you probably heard this with other colleagues, biosecurity.
- 12:08SPEAKER_05: Um, we don't really do much when you go to the coast, but it is thinking about are you going to this shore and then immediately going to a different shore further up the coast?
- 12:18SPEAKER_05: You should be kind of washing wellies, making sure they're dry, just to try and reduce any movement of species that we could be um carrying.
- 12:27SPEAKER_01: That's really good to note as well, because I'm sure a lot of people do go from one coast to another or on holiday and moving between.
- 12:34SPEAKER_01: So, like keeping aware of that.
- 12:35SPEAKER_01: I know there's a lot of stuff about like um like your cross-contamination if like you're somewhere where there's Himalayan balsam or you're helping out in like a river project and then you're going home to a different area of the county or beyond that.
- 12:50SPEAKER_01: Um, so yeah, the kid thinking of it in the marine context as well is really important.
- 12:55SPEAKER_01: Absolutely.
- 12:56SPEAKER_01: Um where are we headed over here then?
- 12:58SPEAKER_01: Any good rock pools you think?
- 13:00SPEAKER_05: Yeah, potentially.
- 13:01SPEAKER_05: So as the tide drops, we'll just keep on finding more and more.
- 13:04SPEAKER_05: But we can look at some of the those upper shore species if you'd like.
- 13:08SPEAKER_05: Yeah, that sounds great.
- 13:12SPEAKER_05: Just mind your footing.
- 13:14SPEAKER_05: So um we do say the greener the seaweed the slippier it is, but you can see it's just absolutely covered, so just take it really easy.
- 13:21SPEAKER_05: Yeah.
- 13:21SPEAKER_05: So here, can you see this kind of this seaweed is spiralling like that?
- 13:26SPEAKER_05: That is spiral rack.
- 13:28SPEAKER_05: Um, and it's just really well adapted to being in this upper shore.
- 13:31SPEAKER_05: It can dry out a lot, up to 95%, be absolutely fine, and then the water will come back up and it just rehydrates itself.
- 13:39SPEAKER_05: So it's amazing how these species have adapted to surviving on the shore.
- 13:43SPEAKER_05: Um, and limb pits are absolutely amazing but often overlooked.
- 13:47SPEAKER_05: So um they they've got these like teeth on their foot which sticks to the rock, and they've now found, and and this was a few years ago, but I think it's still true, that their teeth are the strongest biological material found on Earth.
- 14:00SPEAKER_05: And they're now looking at how they can use that in everyday life.
- 14:04SPEAKER_05: So it's stronger than spider cell, it's stronger than all sorts.
- 14:07SPEAKER_05: And what's really cool is the water comes in, they'll actually move quite far around, uh grazing and and uh eating kind of seaweeds with their foot or the scraping tongue.
- 14:18SPEAKER_05: Um and then when the water goes back out, somehow they find the exact same place on the exact same rock every single time.
- 14:25SPEAKER_05: So that will always be there every time, and over time they kind of grind into the rock perfectly.
- 14:31SPEAKER_05: Um and if you see a limpet that's passed away um and there's like a there's a mark where it used to be, it's called a home scar.
- 14:38SPEAKER_05: That's amazing.
- 14:39SPEAKER_05: So it's just really like you know, how how can they know?
- 14:41SPEAKER_05: They think it might be chemicals, but we're still finding out so much about the marine environment.
- 14:47SPEAKER_05: When did you first do rock pooling?
- 14:48SPEAKER_05: Do you have any like memories as a kid?
- 14:50SPEAKER_05: Absolutely.
- 14:50SPEAKER_05: So I'm really lucky in that my dad was an animal behaviour lecturer at Cardiff Earth, so he's always been absolutely fascinated by wildlife.
- 14:59SPEAKER_05: So I grew up going on like epic wildlife adventures, but also I used to go on his field courses with his students.
- 15:05SPEAKER_05: So I really remember strongly.
- 15:08SPEAKER_05: Um we went to a place called Ken Fig, it's a nature reserve in South Wales, um, and that does have an adult mussel bed.
- 15:16SPEAKER_05: It's absolutely amazing.
- 15:17SPEAKER_05: So you can walk out, there's mussels everywhere, and I remember finding it's a type of sea slug called a sea lemon, and they just literally look like this weird, like splotchy lemon, and it's amazing, and I was absolutely blown away.
- 15:30SPEAKER_05: I remember being so excited, and that just really sparked my interest in the marine environment.
- 15:37SPEAKER_01: And I just wanted to learn more.
- 15:38SPEAKER_01: Right, so we've done upper shore.
- 15:39SPEAKER_01: I don't know what is the like a signaller for like the middle shore part, did you say?
- 15:43SPEAKER_01: We might not see it in that.
- 15:44SPEAKER_01: We might not see it, yeah.
- 15:45SPEAKER_05: So obviously we're doing a shore search survey a bit later.
- 15:48SPEAKER_05: Yeah.
- 15:49SPEAKER_05: Um so low tide isn't until half one and it's a really low tide.
- 15:55SPEAKER_05: Really?
- 15:56SPEAKER_05: Low, low.
- 15:56SPEAKER_05: So I don't think I would have seen it that low.
- 15:58SPEAKER_05: Yeah, so it's it's um so anything under one metre we consider good.
- 16:02SPEAKER_05: This is 0.29.
- 16:04SPEAKER_05: Whoa.
- 16:04SPEAKER_05: Brilliant.
- 16:05SPEAKER_05: So it should we'll should we should find some brilliant things later.
- 16:08SPEAKER_05: But we can start to, if you wanted, go down and start to look within these kind of rocks on that path.
- 16:13SPEAKER_05: Yeah, that's what I think.
- 16:13SPEAKER_05: Maybe we should bring our stuff and we can decanze it.
- 16:17SPEAKER_01: Yeah, and that you were saying about like you've got quite a dedicated group of volunteers that come and help out.
- 16:22SPEAKER_01: What's the importance of kind of people getting from the general public coming and like helping inshore searches, both marine but also like in rivers?
- 16:32SPEAKER_01: Um it's so important.
- 16:34SPEAKER_05: We're very aware at Yorkshire Wildlife Trust that we can't do our job and our work without amazing volunteers and people dedicating their time for free in a voluntary capacity, so we really really value it.
- 16:48SPEAKER_05: It's one of my I'd say proudest achievements at Yorkshire Wildlife Trust is that group of volunteers.
- 16:53SPEAKER_01: Yeah, it's really nice.
- 16:54SPEAKER_01: Like the last time I came on one, they were so willing to like share all their knowledge and kind of help you out, but also just the joy that rock pooling brought them was so nice.
- 17:04SPEAKER_01: It never gets old, you know.
- 17:06SPEAKER_05: You'd think that you know, we've been rock pooling for three or four years now doing these surveys.
- 17:10SPEAKER_05: It might start to get kind of very similar and it doesn't, you know, every time is different, there's always something new, and I think the reason that they're so good at explaining things to newcomers is what we've all found is that going through ID it's actually really difficult.
- 17:28SPEAKER_05: It takes years, and we're by no means experts.
- 17:31SPEAKER_05: Um I think we've all had those kind of challenges when it comes to it, so we we really understand how overwhelm it can be when you come through your first session and you don't know what anything is, and we're just you know reeling off Latin names.
- 17:43SPEAKER_05: Um so I think I think they are very sympathetic to that, and that's why they're so brilliant with any newcomers and explaining kind of everything that we see.
- 17:52SPEAKER_05: Quite relaxing, just like moving about in the lunch.
- 17:54SPEAKER_05: I'm enjoying you can hear sandwich turns, and I've just seen a couple of them diving.
- 17:59SPEAKER_05: But can you hear that kind of screeching call?
- 18:01SPEAKER_05: Yeah, that's sandwich turns, yeah, yeah.
- 18:03SPEAKER_05: Why are they called that?
- 18:05SPEAKER_02: I don't know.
- 18:05SPEAKER_02: That's a good question.
- 18:07SPEAKER_05: Yeah, so it's just these ones kind of flying around here.
- 18:10SPEAKER_05: And that's the thing, sometimes you have to remind yourself, you've got your head like in a rock pool, remind yourself to look up.
- 18:15SPEAKER_05: Yeah, because you know, there could be dolphins, there could be seals, there's amazing birds.
- 18:19SPEAKER_05: So you have to kind of remember not to not to get stuck in the small stuff.
- 18:24SPEAKER_05: Yeah.
- 18:25SPEAKER_01: Have you got a personal favourite find from a rock pooling layout?
- 18:30SPEAKER_01: I have.
- 18:30SPEAKER_05: So my my forever favourite marine creature is a type of fish called a lump sucker.
- 18:37SPEAKER_01: Nice.
- 18:37SPEAKER_05: And if you if you look it up online, they look prehistoric.
- 18:41SPEAKER_05: They are like a dinosaur fish, they're amazing.
- 18:44SPEAKER_05: Um but what they have is a specialized um pelvic fin that has um formed and fused into a disc, a sticky disc, and they'll literally stick themselves to a rock and they'll come into inshore to breed, they'll look they'll lay their eggs, and then the male will stick with the eggs with their sticky sticky disc and just kind of fan the uh the eggs with oxygen.
- 19:05SPEAKER_05: But they they just look so incredible.
- 19:08SPEAKER_05: Have a look online.
- 19:09SPEAKER_05: Yeah, really.
- 19:10SPEAKER_05: They are weird and wonderful, and if we ever I found like a couple when I first started rock pooling, and we haven't found any for uh a year or so, and oh they're they're by far my favourite, always will be.
- 19:21SPEAKER_01: What about these little rocks down here?
- 19:23SPEAKER_01: Or do you think there's not enough water coverage?
- 19:25SPEAKER_01: Let's have a look.
- 19:25SPEAKER_01: Okay, let's have a look.
- 19:27SPEAKER_01: Or that's yeah, let's go around there.
- 19:29SPEAKER_01: Yeah, that looks good.
- 19:30SPEAKER_01: We spoke about like the connection of well, invasive species, and remembering that they're like inland as well as on our shores.
- 19:40SPEAKER_01: But that's quite an interesting connection from like the seaside and thinking about how the like species and our landscapes change as we like move inland to Yorkshire.
- 19:51SPEAKER_01: And I know you're doing a project at the minute called Rivers to Reef, and about that connection, um, whereabouts in the project are you?
- 19:58SPEAKER_05: We're very uh soon into the project, so it launched in March this year, um, but it's already going really well and building momentum.
- 20:07SPEAKER_05: So, just as you've said, um in the past we've often looked at and worked within environments quite separately.
- 20:14SPEAKER_05: So you've got your staff that are working on rivers, and we've got our kind of staff and our volunteers working on marine environments, but you don't often really speak, you keep in your silos.
- 20:25SPEAKER_05: Um, and when you think about it, it makes total sense that you need to be looking at the system as a whole.
- 20:31SPEAKER_05: We need to be zooming out and taking a holistic approach because pollution in one environment can be undermining restoration and conservation work in another.
- 20:41SPEAKER_05: So it has to be tackled from source to sea.
- 20:44SPEAKER_05: So that is uh what all the project is about.
- 20:47SPEAKER_05: Um, at the moment, we're focusing on um a citizen science element that is asking people to sample nitrates and phosphates in our rivers, also we can understand how those um pollutants could be impacting our seas more.
- 21:03SPEAKER_05: Um and something I've kind of learned from uh starting the project is things like the Humber Estuary is the largest freshwater contributor to the North Sea.
- 21:10SPEAKER_05: Wow.
- 21:11SPEAKER_05: So, you know, we've got that on our doorstep in Yorkshire.
- 21:14SPEAKER_05: We should be getting as much information and data as possible and understanding how that can be impacting our coastal and our marine wildlife along the on along the Yorkshire coastline in the North Sea.
- 21:25SPEAKER_01: Yeah, I saw some good like communication about that for even just like if your dog has been treated recently, just don't let them kind of go in the in the rivers.
- 21:35SPEAKER_01: Well, that's awesome.
- 21:37SPEAKER_04: It's a beadler anemone.
- 21:38SPEAKER_04: What was it again?
- 21:39SPEAKER_04: Beedler anemone.
- 21:41SPEAKER_04: So you know, a an anemone like the one that Mino lives in.
- 21:44SPEAKER_05: Awesome! Um but you know, as you can see at the moment, it looks like a weird blob of jelly.
- 21:50SPEAKER_05: But when the water comes back over, these tentacles come out that are absolutely gorgeous.
- 21:54SPEAKER_05: Really?
- 21:55SPEAKER_05: Um but what's really cool about them is that they are these species in particular are quite territorial.
- 22:00SPEAKER_05: But also if there's passing prey, whether it's fish or insects, they've got a um they've got these stinging harpoons that can paralyse passing prey so they can then catch it and digest it.
- 22:11SPEAKER_05: So they're these kind of you know, these active predators, but they're a blob of jelly to us.
- 22:18SPEAKER_05: That's so cool! And again, incredible that they can survive even in this upper shore because they're going to be exposed now for the majority of the day.
- 22:27SPEAKER_05: Yeah.
- 22:27SPEAKER_05: Um so it is incredible how these animals have adapted.
- 22:31SPEAKER_05: Yeah.
- 22:31SPEAKER_05: As you can see, uh barnacle galore.
- 22:34SPEAKER_05: You can see an anemone there with um its tentacles out.
- 22:38SPEAKER_05: Um, and I wouldn't recommend everyone does this, but if I gently touch it, it'll look like it's sticking to my finger, and it's because it's firing those stinging harpoons, but because our skin is too thick, we don't feel it.
- 22:50SPEAKER_05: Yeah, so if I just kind of gently, very gently, it kind of sticks.
- 22:55SPEAKER_05: Oh yeah.
- 22:56SPEAKER_05: And then these sea snails, again, often overlooked, um, but they're a type called a dog whelk.
- 23:02SPEAKER_05: And can you see it's got this kind of channel or this groove here?
- 23:06SPEAKER_05: That's because they've got a specialised drill that will drill into barnacles and in pits, inject them with a chemical that turns them into soup and sucks their insides back up.
- 23:14SPEAKER_05: So they're like the lions of the seashore, they're really, really active predators.
- 23:18SPEAKER_05: That's crazy.
- 23:19SPEAKER_05: Yeah, you just kind of walk past that and think, yeah.
- 23:22SPEAKER_01: It's a shell kind of thing.
- 23:23SPEAKER_01: And then the more you know.
- 23:24SPEAKER_01: Absolutely.
- 23:25SPEAKER_01: Wow.
- 23:26SPEAKER_01: Um, when we were last here, we found that solar-powered sea slug.
- 23:29SPEAKER_01: Oh, damn.
- 23:30SPEAKER_01: That was awesome.
- 23:31SPEAKER_05: And that's not a common find.
- 23:32SPEAKER_05: I think I found that twice with the times I've been rock pooling.
- 23:36SPEAKER_05: And it's just again, you know, you would just normally look over that, but when you learn about what it can do, so they can steal the chloroplasts from things nearby, so seaweeds and things nearby, which just mind-blowing.
- 23:50SPEAKER_05: To give its energy, right?
- 23:51SPEAKER_05: Yeah, it's incredible.
- 23:53SPEAKER_05: So it is this kind of the more you start to learn, it's a snowball.
- 23:58SPEAKER_05: Yeah, I just yeah, I don't understand how anyone can not be absolutely fascinated by it.
- 24:03SPEAKER_05: No, it's incredible.
- 24:06SPEAKER_05: What's really sad is that a lot of people live near the coast but don't know about it, so that's something we really want to do.
- 24:12SPEAKER_05: Oh, nice, good spot.
- 24:14SPEAKER_05: So, what's interesting is that people will come to the beach and the shore and they'll often say, Oh, this, you know, all I found are some dead crabs.
- 24:22SPEAKER_05: This is not a dead crab, this is the shedded skin of a crab, so that's how they grow like a snake.
- 24:27SPEAKER_05: They shed their skin.
- 24:29SPEAKER_05: And so, if I just open up the back and open it up, it's completely empty except for its gills, which it replaces every time.
- 24:36SPEAKER_05: So, this crab will be fine, it'll be living somewhere around here, but it'll just be a bit bigger.
- 24:42SPEAKER_05: That is so crazy.
- 24:43SPEAKER_05: When you lift it up there, it does look quite snake-like.
- 24:45SPEAKER_05: Yeah, and it is, it's just an empty shell, it's not a dead crab.
- 24:49SPEAKER_05: And so you see these, they're called malts, and you'll see them all across the shore.
- 24:53SPEAKER_05: So I've just got a tiny crab there, just living its living its best little life.
- 24:58SPEAKER_05: And just loads of periwings.
- 25:00SPEAKER_04: Is that a shrimp?
- 25:01SPEAKER_04: Oh, where are we looking?
- 25:02SPEAKER_05: I don't know.
- 25:03SPEAKER_04: Here.
- 25:04SPEAKER_05: Oh, it's like um, it's something called an amphipod.
- 25:07SPEAKER_05: Oh.
- 25:07SPEAKER_05: Um, which is like a I think it's like a marine insect.
- 25:11SPEAKER_05: I might need to trick that.
- 25:12SPEAKER_01: But yeah.
- 25:13SPEAKER_01: We can do pop-outs on the podcast.
- 25:15SPEAKER_01: Okay, cool.
- 25:16SPEAKER_01: We we we can uh fact check if you're gonna do it.
- 25:18SPEAKER_01: Yes, please do.
- 25:25SPEAKER_00: Ah, good question.
- 25:26SPEAKER_00: So anthropods aren't insects, they're crustaceans, which puts them in the same group as shrimp, crabs, and lobsters.
- 25:33SPEAKER_00: And that's a nice link for us here in Yorkshire because our coast has a really important crab and lobster fishery.
- 25:39SPEAKER_00: Bridlington is actually the largest lobster port in Europe.
- 25:43SPEAKER_00: In 2021, it landed more than 2100 tons of brown crab and nearly 480 tons of lobster.
- 25:49SPEAKER_00: So those tiny amphiphods you find on the beach are cousins of those crabs and lobsters coming into the harbor.
- 25:54SPEAKER_00: But here's the surprising bit insects are on that family tree too.
- 25:59SPEAKER_00: When scientists look closely at DNA and evolutionary history, they found that insects sit inside the same big branch as crustaceans.
- 26:07SPEAKER_00: It's called pan crustacea.
- 26:09SPEAKER_00: That doesn't mean insects evolved from anthropods or crabs, it's more that they are distant cousins sharing an ancestor a very long time ago.
- 26:17SPEAKER_00: In fact, insects and crustaceans are more closely related to each other than either the spiders or centipedes.
- 26:23SPEAKER_00: So picture a sandhopper bouncing about on a Yorkshire beach, a lobster being landed at Bridlington, and a fly buzzing overhead.
- 26:29SPEAKER_00: They look nothing alike, but they're all part of the same big evolutionary story.
- 26:33SPEAKER_00: My name's Andy Van der Slater Olivier, and I'm the Marine Programme Manager at Yorkshire Wildlife Trust.
- 26:40SPEAKER_01: For people listening at home, like when you pick up something from a rock ball like you just did there, what's your best approach for those things?
- 26:47SPEAKER_05: Good, good question.
- 26:48SPEAKER_05: Um, with crabs, I'd say the small ones like that are fine because they're small, but the bigger ones, there's a very much a right way to hold a crab.
- 26:58SPEAKER_05: Um, I wonder if we'll find a bigger one that I can demonstrate for you.
- 27:02SPEAKER_05: But it's basically either side of its shell.
- 27:05SPEAKER_05: Right.
- 27:05SPEAKER_05: Um, and that's because they can't get you because their claws are kind of in front, but you're not damaging any of the crab.
- 27:12SPEAKER_05: Often you see people holding their abdomen and the top, yeah.
- 27:16SPEAKER_05: And firstly, the crab can pince you pince at you, and but also that abdomen is where they carry their eggs it's the soft part of them, so we don't want to be putting any pressure or damaging that in any way.
- 27:27SPEAKER_05: Um, so yeah, there is a right way.
- 27:29SPEAKER_05: Um, things like fish, I think just be really gentle and put them in a tray with water.
- 27:35SPEAKER_05: Yeah, um, but also if you're happy to leave things be.
- 27:39SPEAKER_05: Like we don't always need to pick them up and get them in in trays and buckets.
- 27:44SPEAKER_05: And what I would say is be really wary of putting things in together.
- 27:48SPEAKER_01: Yeah.
- 27:49SPEAKER_05: Because I think people forget that crabs will eat each other, you know, crabs will eat fish.
- 27:54SPEAKER_05: Um, so you might put two things in a tray and come back and they're not there anymore.
- 27:58SPEAKER_05: So you've got to be really mindful of what you're doing.
- 28:01SPEAKER_01: It's freaky marine life, you've got to be careful.
- 28:04SPEAKER_01: Yeah, exactly.
- 28:05SPEAKER_05: Yeah, they do, they'll it they'll eat each other.
- 28:07SPEAKER_05: But it's um we're doing a bit of work up in Whitby um regarding crab lining and some engagement there because often you do see people um sticking, you know, 10 crabs in a small bucket together, and when you think about it, you know, firstly they'll be eating each other, but they'll also be running out of oxygen, it'll be getting really hot in there.
- 28:27SPEAKER_05: Um, so it's it's just there's some best practice there to reduce your kind of impact on those crabs, which are animals, you know, they are living things and they deserve to be treated as such.
- 28:37SPEAKER_01: Oh, I feel like I'm on the hunt for a like a butterfish or something, those are my favourites.
- 28:42SPEAKER_05: Some of my uh volunteers are eagle-eyed fish people.
- 28:46SPEAKER_05: We've got someone who's great at getting fish, we've got someone who's great at spotting sea slugs.
- 28:50SPEAKER_05: Nice.
- 28:50SPEAKER_05: So we should have a brilliant kind of variety of.
- 28:52SPEAKER_05: What is um this seaweed here?
- 28:55SPEAKER_05: So that it's not attached, so it's probably a bit deeper down.
- 28:58SPEAKER_05: But I think it's a type of seaweed called red rags.
- 29:01SPEAKER_05: Right.
- 29:01SPEAKER_05: It's a really cool one actually, and that beautiful red, but feel how thick it is, it's almost like rubbery.
- 29:06SPEAKER_05: Rubbery, yeah, yeah, yeah.
- 29:08SPEAKER_05: So it's a really, really interesting seaweed.
- 29:10SPEAKER_05: But it is it's interesting when you see things washed up as well, which we wouldn't record on our shore search surveys because you know they're not attached, we don't know where they've come from.
- 29:19SPEAKER_05: But you start to get an insight into what's a bit deeper on our shores when it's washed up.
- 29:23SPEAKER_05: And what's interesting is here, like you might see this and think that's a bit of litter, um, but that's just some old sugar kelp that's kind of lost all of its colour.
- 29:31SPEAKER_05: So it does, it just looks like a bit of plastic, doesn't it?
- 29:34SPEAKER_05: Yeah.
- 29:34SPEAKER_05: So I think that's half of the battle sometimes when you're beach cleaning or other activities is knowing what's natural and what's not.
- 29:41SPEAKER_02: Yeah.
- 29:41SPEAKER_05: Um and again, if we can't tell, which we can't a lot of the time, wildlife stands no chance, so you can see why they're ingesting these plastics and these bits of litter.
- 29:50SPEAKER_05: Oh, this is a lovely, I love this red seaweed.
- 29:53SPEAKER_05: Oh wow.
- 29:54SPEAKER_05: Um it's called like comb weed, um, but it's just got you can you see it kind of almost all looks like a comb, it's a bit degraded.
- 30:02SPEAKER_05: Um but it's just really beautiful, and when you look at it like under a microscope, I just love the structure of it, it's so nice.
- 30:08SPEAKER_05: Yeah, that is gorgeous.
- 30:10SPEAKER_05: Yeah, they are lovely.
- 30:12SPEAKER_05: Um we've got something called the Yorkshire Inns Mapper, which uh one of our teams manages and is um in collaboration, I think, with Yorkshire Water, and that's going to be really, really important.
- 30:23SPEAKER_05: Um but they've just recently added marine species onto that, so that's something we're looking at at the moment, it's making sure we're reporting what we find through that.
- 30:32SPEAKER_01: Oh, that's really cool.
- 30:33SPEAKER_01: So kind of the database is growing and then that collective mapping is getting stronger.
- 30:37SPEAKER_05: Because it's funny, um, we were at a workshop the other day where they said um the last record of Pacific oysters at Spurn Point was in 20, I think they said 2012.
- 30:47SPEAKER_05: Um, we see them every single time we go out there.
- 30:49SPEAKER_05: So clearly something's not getting through, so we need to make sure that the data's getting where it needs to be to be accurate.
- 30:56SPEAKER_01: That's interesting, yeah.
- 30:57SPEAKER_05: They're everywhere, like they're they're really prolific at spern.
- 31:00SPEAKER_01: So yeah, and you've done loads of oyster work at spurn, right?
- 31:03SPEAKER_05: Yes, we're native oysters.
- 31:04SPEAKER_05: So the Pacifics are the invasive species there that you know, in a lot of ways, you know, they they breed quicker, they can tolerate more kind of conditions, and so they do outcompete those native species.
- 31:18SPEAKER_05: So that's what we're trying to do is um intro reintroduce native uh oysters and give them the best chance of success.
- 31:24SPEAKER_05: Yeah.
- 31:28SPEAKER_01: Are there any things that you really hope that we find today in the shore search?
- 31:31SPEAKER_05: I would love to find that lumpsucker, yeah.
- 31:34SPEAKER_05: Um, another favourite is on kelp.
- 31:36SPEAKER_05: There's often things called Blu-rayed limpets, and they're this small limpet but with the most electric blue lines on them.
- 31:43SPEAKER_05: So it's always a great day when you find a blue-rolled limpet.
- 31:46SPEAKER_05: Um, but also any sea slugs, they're always a favourite.
- 31:50SPEAKER_05: They are good.
- 31:51SPEAKER_01: The colours in like marine life is are just incredible.
- 31:54SPEAKER_05: Yeah, I I totally see why it often inspires art.
- 31:58SPEAKER_05: The structures, yeah, the shapes, the the colours, it's yeah, it's it's really really beautiful.
- 32:06SPEAKER_01: If you have uh two takeaways for our listeners at home, the first takeaway would be about kind of rock pooling, and the second takeaway would be about just kind of like nature or Yorkshire or marine in general.
- 32:25SPEAKER_05: I think the first takeaway is come to the coast and have a look.
- 32:29SPEAKER_05: Uh, come to one of our activities, or if you're interested in doing surveys, get in touch with the Yorkshire Wildlife Trust, and because it is really a brilliant experience.
- 32:38SPEAKER_05: Um, but do kind of have a look and explore in your own time, um, and and you can just start to find this whole other world that you are not aware of.
- 32:48SPEAKER_05: So please do take the time.
- 32:50SPEAKER_05: And I think with nature, like for me, nature's really really important for kind of my mental health and well-being.
- 32:56SPEAKER_05: Yeah, so I'd encourage you to get out, even if it's you know 10 minutes in a day, really try and kind of engage with it, but also slow down the pace.
- 33:04SPEAKER_05: You know, if you do come rock pooling, sit in one spot and really take your time and look for those species and that wildlife.
- 33:12SPEAKER_05: Um, but do that for any kind of nature that you're watching, yeah.
- 33:15SPEAKER_05: And I find it really, really helpful.
- 33:18SPEAKER_01: I think that's good as well because like it can be quite easy to be like, oh, I've not found anything interesting, or I've just sat here and everyone else has found solar power sea sleds and stuff, but actually the point of it isn't it's not like a it doesn't matter what you see or what you find, it's actually the experience of going and doing it that is the the main thing.
- 33:39SPEAKER_05: Absolutely, and what people kind of sometimes forget is recording the common stuff is just as important, if not more valuable, than the exciting kind of one-off finds that you sometimes get.
- 33:51SPEAKER_05: Yeah.
- 33:51SPEAKER_05: Um, we really need to be recording everything that we see, um, and that's really really important.
- 33:57SPEAKER_05: Yeah.
- 33:58SPEAKER_05: Um it's funny, I find um talking about kind of that mental health and well-being where sometimes you know life can get a bit busy and overwhelming, and I just feel quite stressed.
- 34:08SPEAKER_05: And I go to the sea and look out at it, and it sounds ridiculous, but it makes me feel insignificant, and that helps me so much to just remember that my problems are not that big.
- 34:19SPEAKER_05: You know, the world will go on, the sea will keep being the sea.
- 34:22SPEAKER_05: Yeah, this expansive, crazy, amazing place that we don't see, you know, a fraction of.
- 34:28SPEAKER_05: Um, and that really helps me to kind of rationalise my problems, and I find it really, really valuable.
- 34:35SPEAKER_01: Yeah, it puts everything into perspective, doesn't it?
- 34:37SPEAKER_01: Definitely, yeah.
- 34:38SPEAKER_01: And a takeaway about nature in general, Yorkshire or being outdoors.
- 34:43SPEAKER_05: I think just it's everywhere, you know, even if it's going to a local park environment like your local nature reserve, um, just take the time to explore where you live.
- 34:55SPEAKER_05: You know, I've just talked about my family coming to visit, and that's making me appreciate what's on my doorstep.
- 35:01SPEAKER_05: You don't need to travel far.
- 35:03SPEAKER_05: You know, explore the nature um close to your home and kind of see what you can find.
- 35:08SPEAKER_01: Yeah, yeah.
- 35:09SPEAKER_01: I actually did something the other day which was quite good for that.
- 35:12SPEAKER_01: I did a colour walk, so I did it with a group of friends, and we all gave each other a colour, and then as you were going on along, you took photos or you noticed the thing of that colour.
- 35:22SPEAKER_01: So it was like flowers in pink and then different pink things as you were going, and leaves that were maybe in that colour tone.
- 35:28SPEAKER_01: And actually, that would be a really good one to do at the coast because of how many different colours there are.
- 35:32SPEAKER_01: But like you say, that was something I could do on my doorstep, and it's something I could do here as well.
- 35:37SPEAKER_05: I think I want to be friends with your friends, yeah.
- 35:39SPEAKER_05: And you but yeah, no, I I think often people do feel like they have to travel further afield, and we all kind of do that, but I think yeah, nature's everywhere, yeah.
- 35:51SPEAKER_05: Even in a busy city, you will find nature there.
- 35:54SPEAKER_02: Yeah.
- 35:54SPEAKER_05: Um, so do really take your time to kind of look at what what's close to home and appreciate it.
- 35:59SPEAKER_01: Yeah.
- 36:00SPEAKER_01: Um imagine that we're here in a hundred years' time.
- 36:04SPEAKER_01: What do you hope to see?
- 36:07SPEAKER_01: Well, that's such a such a big question.
- 36:10SPEAKER_05: For me, you know, it would be a biodiverse and thriving sea.
- 36:16SPEAKER_05: You know, it would it would be healthy, you wouldn't see litter on the beach, you'd only see natural things.
- 36:22SPEAKER_05: Um, but for me, I think as well, seeing local people appreciating what's on their doorstep and being aware of it.
- 36:30SPEAKER_05: Um, it's amazing.
- 36:31SPEAKER_05: We get a lot of school visits at our Living Sea Centre at Flandre.
- 36:34SPEAKER_05: Yeah, and lots of those kids that have grown up in Bridlington, in Scarborough, in places along the coast have never been rock pooling.
- 36:42SPEAKER_05: So, you know, that's to me it seems like a brilliant activity to do with kids.
- 36:46SPEAKER_05: It's eye-opening, it's engaging, and and most people haven't done it.
- 36:51SPEAKER_01: Yeah.
- 36:51SPEAKER_05: Wow, thank you so much for coming on the podcast.
- 36:54SPEAKER_05: It's been amazing.
- 36:55SPEAKER_05: It's been brilliant.
- 36:56SPEAKER_05: Um yeah, we want to advocate for marine because it's often people don't know about it.
- 37:01SPEAKER_05: So um, we're we're lucky that we've got a big marine team within Yorkshire Wildlife Trust, relatively.
- 37:06SPEAKER_05: Yeah.
- 37:06SPEAKER_05: Um so if you want to find out more about the brilliant work we're doing, um, I've got plenty of colleagues.
- 37:11SPEAKER_05: Well, yeah.
- 37:15SPEAKER_01: I was gonna say, I'm sure we'll have some more of your colleagues on in the next.
