- 0:02Speaker 1: Hello, and welcome to Reised Children's Story Hour. It's a
- 0:05reminder is a reading service intended for people who are
- 0:09blind or of other disabilities that make it difficult to
- 0:12reprinted materials. Today we will be reading from various books
- 0:16on trees. Your reader today is Diane. We will begin
- 0:21with a book, The Magic and Mystery of Trees. It
- 0:25was published by Penguin DK, a division of Penguin Random House,
- 0:34and it's a copyright year of twenty nineteen and the
- 0:37author is Jin Green. What is a tree? A tree
- 0:43is a huge plant that towers above us. You find
- 0:47trees standing alone in people's yards, are clustered together in
- 0:50thick forest. Trees are true wonders of nature. Some species
- 0:55can grow taller than fifty cars stacked on top of
- 0:59each other. Trees can live for hundreds of years, and
- 1:03the very oldest are thousands of years old. Every part
- 1:06of a tree works together, from the deepest roots that
- 1:10burrow through the earth to the smallest leaf on the
- 1:13highest branch. Every part of a tree is working hard
- 1:17to help it survive. When you get to know these
- 1:19silent giants, you'll never look at trees the same way again.
- 1:26Where in the world from rocky coast to lush valleys.
- 1:31Trees are found almost everywhere forests or places where many
- 1:35trees grow together. Ken's most famous tree, the maple, produces
- 1:41maple syrup. The world's tallest trees, redwoods live in western
- 1:46North America. The biggest rainforest in the world is the
- 1:51Amazon in South America. Tropical rainforests grow close to the
- 1:55equator around the Earth's middle, where it is very hot
- 1:58all year round. Monkey puzzle trees grow in Chili at
- 2:02the tip of South America. Broadly forests to grow in
- 2:07parts of North America and Europe with mild climates. Forest types.
- 2:14There are three main types of forest, broadly forest, conifer forest,
- 2:20and rainforest. Each of these forests is made up of
- 2:23different types of trees. A huge conifer forest stretches across
- 2:28northern North America, Russia, and northern Europe. These places have long,
- 2:34snowy winters. Coconut seeds can float for miles before finding
- 2:39a place to grow. Eucalyptus of gum trees grow in
- 2:45Australia's dry forest. They keep their leaves all year round.
- 2:50Carie pines live only in New Zealand. They can get
- 2:54very old and large forests cover almost a third of
- 3:00Earth's dry land. How trees live? You've never seen a
- 3:06tree eat a bowl of noodles or a peanut butter sandwich,
- 3:10So what do they eat? As long as it has sunlight, water,
- 3:13and a gas called carbon dioxide, a tree can live, grow,
- 3:18and even make its own foods. The amazing food making
- 3:22process of plants is called photosynthesis. Trees are tough, but
- 3:27they must stay warm to survive. The water and the
- 3:31trees leaves freezes, it can't make food for itself. Mil time,
- 3:36a tree's green leaves soak up light from the sun.
- 3:40Then they use energy from the light to mix carbon
- 3:43dioxide and water. This makes a sugary liquid called sap,
- 3:47which is the tree's food, making oxygen. While they are
- 3:53busy making sap, the trees leaves give off a gas
- 3:58caught oxygen. All animals include us breathe in oxygen and
- 4:02breathe out carbon dioxide. There were no plants such as trees,
- 4:06we wouldn't have air to breathe. Summer days, broad leave
- 4:11trees only make food in spring and summer because there
- 4:15is more sunlight. They lose their leaves in the fall.
- 4:18Conifers can have leaves or needles. They keep making food
- 4:23throughout the winter types of trees. With so many trees
- 4:29growing around the world, it can be tricky to tell
- 4:32one leafy plant from another. Luckily, there are only two
- 4:35main families of trees, broad leave trees and conifers. Broad
- 4:41leaves have wide, flat leaves. They all make flowers, although
- 4:45some are almost too small to see. Their seeds ripen
- 4:49inside juicy fruits such as plums or figs. Most broad
- 4:53leaved trees drop their leaves and fall and grow new
- 4:56ones in the spring. Conifer have long, thin leaves called needles.
- 5:02Many conifers are called evergreens because they keep their leaves
- 5:05all year round. Conifer seas are found inside hard, bumpy cones,
- 5:10such as pine cones. The leafy part of the tree
- 5:15above the trunk is called the crown. It comes in
- 5:18different shapes. Many broad leaves trees are wide and round,
- 5:22while conifers are often shaped like cones. The branches of
- 5:26a round tree spread themselves evenly upward and outward from
- 5:30the trunk. A broad tree has branches that spread farther
- 5:35to the sides than upward. These trees have branches that
- 5:39grow up and out to create a wide, flat shape.
- 5:42Oval trees have a rounded shape that is taller than
- 5:46it is wide. A weeping tree is branches that drop
- 5:49down where palms are broad leave trees that grow in
- 5:53hot countries, and like other trees, they don't grow side branches.
- 5:59Some trees have closely packed branches that grow up where
- 6:03many conifers are tom thin a cone shaped trees. Branches
- 6:07get shorter as they go up the trunk, ending in
- 6:11a pointy tip. Parts of a tree. Branches grow from
- 6:17the trunk. They divide to form smaller branches, which end
- 6:20in twigs. Leaves sprout from twigs. Flowers and fruit grow
- 6:25from twigs. At certain times of the year canopy high
- 6:29above the ground. Twigs and leaves weave together to form
- 6:32a dense, dark blanket called the canopy. The stump. When
- 6:37a tree is cut down or its trunk breaks, it
- 6:41leaves behind a stump. Trunk is a sturdy trunk grows
- 6:49from the ground. It is very strong and supports the
- 6:51weight of the branches. The bark is a thin, tough
- 6:55layer that covers the trunk roots underground. Roots hold the
- 7:01tree steady in the ground wherever they grow. All trees
- 7:05have the same parts roots, A trunk branches and leaves
- 7:11secret roots. In the damp, dark world below, roots spread
- 7:17through the soil to form a woody network. Up to
- 7:20a third of the tree a is hidden underground. Cozy homes.
- 7:26Rabbits and tiny creatures such as worms and beetles live
- 7:31among the roots. Holding tight roots have two main jops. First,
- 7:36they hold the tree firmly in the ground so will
- 7:39not blow over in a storm. Second, they draw water
- 7:42contain minerals from the soil so the leaves can make food.
- 7:47Some trees have a big main root called a taproot.
- 7:50While most roots grow sideways, the tap root shoots straight down.
- 7:56A tree's root network is often whiter than the tree
- 7:59is tall, so that it can find as much water
- 8:02as possible. Trees do most things slowly, but they drink
- 8:07very fast. A big tree can suck in over one
- 8:10hundred gallons of water from the soil every day. Pollution
- 8:15tree roots are very sensitive. They can sense pollution in
- 8:19the soil and avoid it by growing in a different direction.
- 8:23Water seekers the main roots fight into smaller ones. The
- 8:27smallest ones at the end of the root are called rootlets.
- 8:31They are covered in fine hairs that can sense water.
- 8:35Water travels up the roots big and tough. The main
- 8:39roots are strong and woody like branches. Each root tip
- 8:43has a tough cat to push through the soil as
- 8:46it grows. These big roots can extend to the ground
- 8:51up to five feets. Trunk and bark. A tree's trunk
- 8:57supports us branches, just like your skeleton hopes of your body.
- 9:00The trunk has to be very starting to support the
- 9:03huge weight of all the branches. A tree simply wouldn't
- 9:06be a tree without a trunk. Inside the trunk. At
- 9:09the center of the trunk is the heartwood. This grew
- 9:13when the tree was young. It is surrounded by sapwood,
- 9:17which contains tiny tubes that carry water from the roots
- 9:20to the leaves. Between the sapwood and the outer bark
- 9:23is a very thin layer called the folham. This carries
- 9:27sugar from the leaves to the rest of the tree.
- 9:31Tree rings provide clues about the tree's history. Wide rings
- 9:35show years when the tree grew quickly. Narrow rings show
- 9:39when the tree grew only a little because conditions were
- 9:42too cold or dry. Bark like this piling birch bark
- 9:48is the outer layer of the trunk. It stops the
- 9:51tree from drying out and protects it from insects and
- 9:54fung guy. Young trees have smooth bark. As trees get
- 9:59o their bark cracks, pels and becomes more wrinkly, like
- 10:03the bark of this scaly tree. Different types of trees
- 10:06have different bark. Bark is also home to delician licians,
- 10:13like the blotchy yellow ones here. Try making bark prints
- 10:17by rubbing crowns into a piece of paper placed on bark.
- 10:21The texture will come through leaves. Next time your outdoors,
- 10:28take a close look at a leaf. Leaves are very
- 10:30special because it's in the leaves that the tree works
- 10:33its magic by making its own food. Water pumpers. Theins
- 10:40are like tiny pipelines running through the leaf. They take
- 10:44in water from the tubes, and the trunks have wood
- 10:47and carry food made by the leaves to the rest
- 10:50of the tree. Light catchers broad leaf trees spread their wide,
- 10:55flat leaves to capture as much sunlight as possible. Each
- 10:59leaf is like a min it's your solar panel, soaking
- 11:02up energy from the sun. Leaf shapes each tree has
- 11:07leaves with a slightly different shape. They can be long
- 11:10and thin, or wide and round. Flat. Round leaves are
- 11:13good at catching sunlight, but also lose more water. Trees
- 11:19can't move from place to place, but they can very
- 11:21slowly turn their leaves to face the sun. Leaves are
- 11:25green because they contain a natural pigment called chlorophyll, and
- 11:30fall the green phades and other colors than leaves can
- 11:32be seen. They turn yellow, orange, and brown. Follow on
- 11:39one maple tree through the seasons. Spring first shoots after
- 11:46the cold, dark winter. Spring is the season of a
- 11:48new beginning. The weather gets warmer and days grow longer.
- 11:53Trees know when the winter has passed, and spring the
- 11:56tree grows green buds. The buds open, uncurling and spreading
- 12:00new leaves in the sunshine. The tree flowers bloom summer
- 12:07hot days. Like many humans, trees love the sunshine. Summer
- 12:13is the hottest season, when the longest days of the
- 12:15year and the trees are ready to soak up the sunlight.
- 12:19Branches are covered with leaves that form a dense, shady layer.
- 12:23In late summer, the trees fruits start to grow. Trees
- 12:26do most of their growing during the summer months, fall,
- 12:31changing colors, and fall. The weather turns cooler and days
- 12:35get shorter, fruits and nuts ripen, and trees spread their seeds.
- 12:40Flat wide leaves can catch blustery autumn winds, so the
- 12:44tree sheds them to avoid damage to its branches. Its
- 12:48green leaves turn yellow, orange, red, and brown, then drift
- 12:52down to the ground winter frosty flakes. Winter's the cold
- 12:57is season with the shortest days. The tree shedded sleeves.
- 13:01It may look dead, but is only sleeping as it
- 13:04waits for spring. The tree has moved the stalks of
- 13:07sap It's spent all summer making away from its branches
- 13:11and in to its roots. Flowers, fruits, and seeds. Trees
- 13:17need to make new trees for the forests to stay healthy.
- 13:21That's why they grow flowers, fruits, and seeds. The flowers
- 13:24bloom in spring. During the warm days of spring, bees
- 13:28buzz from tree to tree, visiting as many flowers as
- 13:31they can. Seeds are little bundles that contain a whole
- 13:35new tree ready to grow. They ripen in summer and fall.
- 13:39Each seed needs to find a good place to grow. Trees,
- 13:43like all living things, are born, grow and eventually die,
- 13:47but they leave behind the promise of new forests still
- 13:51to come. Flowers. Trees that want to attract insects have large,
- 13:57showy flowers, while once it's red pollen on the wind
- 14:01have tiny, delicate ones. Some tree flowers are so small
- 14:06that they can be tricky to spot, but they have
- 14:08vital work to do. Blossoms and spring apple and cherry
- 14:13trees are covered with flowers we call blossoms. These flowers
- 14:17make the trees look beautiful, but their main job is
- 14:20to tell insects such as bees, that there's a tree
- 14:23ready for them. Did geno flowers have male and female parts.
- 14:29The male part produces pollen, the female part makes eggs.
- 14:34Male pollen must combine with these eggs to make them fertile,
- 14:38and then they can ripen into seeds. Little helpers. Insects
- 14:44visit flowers to drink a sweet liquid called nectar. Any
- 14:48pollen grains from the flower that get on the insect's
- 14:51body rub off inside the next flower the bee visits.
- 14:55This makes the next flower fertile grains of pens stick
- 15:00to the bees hairy body. The bright colors and sweet
- 15:04smells of flowers tell the insects that nectar is ready.
- 15:09Pine and fir trees spread their pollen on the winds
- 15:16fruits and seeds. Once the tree flowers have been made
- 15:19fertile by pollen, it is time for seeds to grow.
- 15:22They can develop inside fruits, cones, hard shells, or papery
- 15:26covers conifer seeds. Most conifer trees make their seeds inside cones,
- 15:32not fruits. When the seeds are ripe, the cones open
- 15:36the light. Papery seeds tumble out and blow away on
- 15:39the breeze. You and juniper are unusual conifers. They make
- 15:44small bitter berries. Birds love them fruits. You've ever enjoyed
- 15:49a crisp apple or juicy cherry. You've eaten the fruit
- 15:52of a rod leave tree. Mangoes, peaches, and cherries contain
- 15:57just one large seed called a stone. Apples, oranges, and
- 16:01lemons have many small seeds called pips, blown on the wind.
- 16:08Tree seeds must be scattered far and wide so that
- 16:11new trees can grow. Some seeds are scattered by the wind. Sycamore, maple,
- 16:16and ash trees have light winged seeds that spin through
- 16:19the air, carried by currants. Trees that live by rivers
- 16:24and oceans make seeds that float the current carries them away.
- 16:29Coconut palms grow on the seashore in warm places. Right
- 16:33coconuts PLoP into the water, the tide washes them away
- 16:37to take root on distant coasts. Coconuts are light enough
- 16:43to float animal assistance. Animals live The bright colors and
- 16:53mouth watering smells of fruit. Trees get animals to spread
- 16:56their seeds for them by putting them inside delicious adventure
- 17:01time for children. The best place to grow up is
- 17:04near our parents, who provide everything we need. Trees are
- 17:08very different. They like their seeds to travel alone to
- 17:11distance places. Fast moving animals provide a perfect transportation system.
- 17:17Buried nuts in file. Squirrels and blue jays prepare for
- 17:21winter by burying nuts and acorns. These nuts provide a
- 17:25handy source of food during the long bleak months of winter,
- 17:29as long as the animal doesn't forget where its food
- 17:32is buried. Any forgotten seeds will sprout into new trees
- 17:36in the spring. Monkey dung monkeys leave to feast on figs.
- 17:41They can digest the juicy flesh, but the hard seeds
- 17:44pass right through the animal's bodies and come out in
- 17:48their pooh. As the monkeys wander from tree to tree,
- 17:54the seeds in their dung get scattered all over the forest.
- 17:58Monkey pooh contains all the nutrients a seed needs to
- 18:02sprout and grow strong and healthy from seed to tree.
- 18:08Trees are the tallest living things in the world, but
- 18:10they are born from tiny seeds. Growing to the full
- 18:14height can take one hundred years. Here's how young oak
- 18:17sprouts from a little acorn to grow taller than a house.
- 18:21Seeds are full of food to keep the seed lingoing
- 18:24until it can make its own food. Sprouting, the seed
- 18:28lands in moist soil in a warm liked place. Big
- 18:32changes start to happen. The seed swells and the case
- 18:36splits open. A tiny root pokes down to take in water.
- 18:41Small green shoot pushes up through the soil. Once the
- 18:45first leaves unfurl in the sunlight, the young plant can
- 18:48make its own food. A new little tree is born.
- 18:52Growing older. Humans grow during their childhood that we stop
- 18:57when we become adults. Trees are different continue growing. What's more,
- 19:01they can live at least five times as long as
- 19:04we do. At one hundred years old, many trees are
- 19:07still youngsters. Oak trees keep getting wider for five hundred
- 19:13to six hundred years. Taller and wider As the tree
- 19:17gets older, its upward growth slows and finally stops when
- 19:21it reaches full height. But if there is space, its
- 19:25branches and trunk continue getting wider. The trunk of a
- 19:28big old tree grows about one inch wider each year.
- 19:33Lie after death, no living thing goes on forever. Trees
- 19:38can live for hundreds of years, but in the end
- 19:41even they grow old and die. Wind shake the dead
- 19:44tree until its trunk cracks and it comes crashing to
- 19:47the ground a new home, but that's not the end
- 19:51of the story. A dead tree becomes a home for
- 19:53thousands of small creatures that like damp, dark places. Little
- 19:59beests such as plugs, worms, wood lice, centipedeses, insects, and
- 20:04spiders move in. Up to a third of all creatures
- 20:08that live in the forests like to live in or
- 20:10eaten or eat rotten wood. Recycling nutrients. Small creatures and
- 20:16fungi feast on rotten wood and break it down. This
- 20:20allows the raw materials that form the tree to return
- 20:23to the soil. These nutrients feed young trees and other plants,
- 20:28giving them a good start in life. Moss, ferns, and
- 20:32flowers take root in the squishy nutritious wood of rotten
- 20:37logs and tree stumps. Fungi spread their threads through the
- 20:41damp wood, and mushroom sprout from the trunk. The fallen
- 20:49trees have left a gap in the forest canopy, allowing
- 20:53light to reach the ground. This helps ceilings flourish, sometimes
- 20:57as seedling will even sprout from a log. Tree partners.
- 21:03Trees grow and change so slowly that it's hard to
- 21:08tell how busy they really are. Year after year, trees
- 21:11stand still and silent, but there's a lot going on
- 21:15under the surface. Trees are mysterious things. Recently, scientists have
- 21:20found out that the trees and a forest work together.
- 21:23They make friends and support one another. Trees look after
- 21:26their neighbors and mother trees pass food to their children
- 21:30and older trees within the family. We now know trees
- 21:34have senses. They can smell, taste, touch, and feel pain
- 21:38like we do. Trees can sense danger and defend themselves
- 21:42against enemies. We are learning that there's a lot more
- 21:45to trees than we ever imagined. Living together life in
- 21:50the natural world is tough. It's easier for trees to
- 21:53survive when they help one another. Trees living in a
- 21:56forest grow best if all the trees are healthy. If
- 22:00one tree is in trouble, the others help it. Trees
- 22:03also work together to make the forests warmer and more
- 22:06sheltered in winter and cooler damper and shadier in the summer.
- 22:11Family and friends trees of the same species look after
- 22:15one another. Oak, beech, and spruce trees like to share
- 22:19water and food with only their own kind. But in
- 22:23some places trees of different types look out from one another.
- 22:27Too stronger together, trees grow wider until they reach the
- 22:32next tree. This creates a roof of branches and leaves
- 22:36that protects the forest from storms. If too many trees
- 22:39die and leave gaps, strong winds can enter and wreck
- 22:43the forest. The tree is damaged and starts to die,
- 22:46its neighbors will pass it food to keep it alive.
- 22:51Roots roots spread through the soil to form a hidden web.
- 22:55Forest neighbors stand touch with one another and pass food
- 22:58to each other through their roots. Wood wide web trees
- 23:04like to keep in touch with each other. Experts have
- 23:07found that it's not just roots that link the trees
- 23:11in a forest. They are also connected through fungi, the
- 23:14living things we know as much as we know as
- 23:18mushrooms the fungi network. They are sort of like a plant,
- 23:25but they cannot make their own food. Instead, they make
- 23:27a network of threats called high fee, which break down food.
- 23:33The high fee can swap food, water, and even messages
- 23:37with tree roots. Fungi help trees by cleaning up pollution
- 23:43and warding off other types of fungui that can make
- 23:46the trees sick. In return for the fungal network, trees
- 23:53give water and food to their fungi. Forest family trees
- 23:59are the same species act like a family. When a
- 24:02ceiling is struggling, its mother steps into help. Trees that
- 24:05are very old, are damaged, are not forgotten. Even the
- 24:09strongest trees can be attacked by disease or insects and
- 24:13need help every now and then. By helping each other,
- 24:16the trees make sure the forest says as a hose,
- 24:19stays strong. Carrying mothers, full grown trees take care of
- 24:23younger and older trees. Many young trees sprout directly below
- 24:27the mother tree, but the youngsters don't grow well in
- 24:30the shade. The mother keeps them alive by passing them
- 24:34sap in nutrients until they are tall enough to find
- 24:37the light. Older trees often block light from reaching younger ones,
- 24:42far from damaging them. However, it turns out to be
- 24:45helpful because growing slowly when they are young helps trees
- 24:49live longer. Helping hand, this stump can't make food without leaves,
- 24:54but somehow it is still light. The trees of the
- 24:57forests are feeding the old stump through their roots. This
- 25:00stump might even be the full grown trees. Mother stumps
- 25:05can live for hundreds of years without leaves. We will
- 25:13have to finish this story next time, so this concludes
- 25:16our story hour for today. Please join us next time
- 25:20as we will read more stories, fables and fairy tales.
