Transcript of Temperate Rainforest
- Rarely goes below freezing in the winter Mild Climate Temperature Precipitation - Most forests receive 120 to 150 cm precipitation per year, mostly rainfall Supplies and gear to bring Rain Gear - The weather can change quickly
- Boots, rain jacket, rain pants, umbrella
Insect Repellant - There are mosquitoes, black flies, deer flies and horse flies.
- Wear long sleeved clothing and apply insect repellant on any areas with exposed skin.
Water - The water in the forest may not be safe to drink What are some threats to this biome? Human activities threaten rainforests. It takes temperate rainforests several hundred years to mature, so fires pose a lasting danger. Another threat is clearing of rainforests, for the use of farming, plantations, dams or mining. Rainforest timber is valued for its beauty and usefulness. However, rainforest trees grow slowly so it is not economical to grow them in plantations for timber. Currently, the Huon pine (over 2000 year old tree) and King Billy pine cannot be exported. Endangered Species Golden lion tamarind monkey, toucans and parrots, jaguar, gorilla, poison dart frog, manatee, Bengal tiger, chimpanzee, harpy eagle, orangutan. Weather Report Warnings Where is it? Native Plants Native Animals Abiotic Factors Biome's Place on Earth Temperate Rainforests do not cover most of the earth and appear very little in North American, South American, European, Asian, Australasian and African regions. Soil - Plants obtain nutrients mainly from it.
Sunlight - Source of energy for producers.
Water - All living organisms need water to survive Adapted to many things such as water limitation, differentiating soil, and evolving climates. Another adaption is seed dispersal. Sometimes the trees will develop berries that animals will eat, like wild turkeys, quails, foxes and waxwings. When the animals eat these berries, the seeds disperse to the forest floor and soon more Red Cedars will grow. Western Red Cedar Douglas Fir An adaptation for this tree is the cork-like bark that it develops. It is thicker than many other species of trees. Their roots are also adapted because of the way that they grow directly out of the trunk, making it stronger and sturdier and less likely to tip over. Stinging Nettle One of the adaptations this plant has is it’s unattractive flowers. They rely on the wind for pollination instead of insects and animals, so their flowers have tiny petals, are unscented, and can be dull in colour. This saves the plant energy to use somewhere else. An adaptation for this animal is to eat different foods when its habitats changes. Their tongues and toes are also very long and dexterous so that they are able to feed on berries or insects from rotting logs. They also have colored vision for finding berries. Black Bear An adaption for this solitary, lone predator is its big paws and huge claws. These adaptations are key to its survival because they use them to climb up and down steep mountains, trees, and rocky areas. Their long tail also helps them keep balance in doing these things. Mountain Lion Elk Elks' teeth are a big adaptation. They have sharp incisors to easily bite off plants high up on the trees or forest floor, and broad, flat molars for mashing when eating the plants. Their legs are also packed with muscles so they can out-run any predators that they might come across. Biotic Interactions Parasitism = Bush tick: The Bush Tick latches onto a hosts body and double their body weight in blood, then drops off of its hosts and digests the blood.
Mutualism = Foliicolous lichens (fungi) and alga (a type of algae): The alga produces carbohydrates as food for the fungus while the fungus creates a protective structure for the both of them.
Predation = Rear-Fanged Snake and Rain Frog: The Rear-Fanged Snake, the predator, swallowing it’s prey, the Rain Frog. Temperate forests are where many of our favorite foods first came from. Walnuts, apples, mushrooms, and maple sugar are all foods of the temperate forest. The soil in temperate forests is rich in nutrients. Temperate forests are important for people, too. Many trees that people use for timber to make houses, ships, and furniture grow in temperate forests. Trees from temperate forests are also used to make paper and other products. The land beneath these forests is often very rich and good for farming. People have cut many temperate forests to make space for farms. Temperate forests provide people with many more resources than just wood and farmland. Clean air and clean water are direct benefits of a healthy forest. In countries like Australia, protection of temperate forests is critical to maintaining clean water. In areas where the forest has been clear cut, the soil loses its nutrients and may wash away. Over time, only a few plants can grow there. Fallen leaves create leaf litter. Leaf litter is one of the most important parts of the temperate forest. This is where the forest recycles most of its nutrients. Inside and beneath this leaf litter, thousands of small animals live, including many invertebrates like beetles, millipedes, centipedes, and ants. Unseen microscopic creatures such as fungi and bacteria live there too. All these organisms help break the leaf litter into nutrients other plants and animals can use. Coastal temperate rain forests foster a hugely disproportionate share of the world's biological production. They accumulate and store more organic matter than any other forest type (including tropical rain forests) - as much as 500-2,000 metric tons of wood, foliage, leaf litter, moss, other living plants, and organic soil per hectare. The adjacent waters are productive as well. The upwelling zones and cold-water currents that bathe the edges of coastal temperate rain forests account for a substantial share of the biological production of the oceans. The productivity of these marine ecosystems is enhanced by the nutrients and organic debris washed out of the coastal watersheds. How Climate Change Can Affect This Biome Temperate rainforests require a high annual precipitation because trees are mostly found in this biome. The plants and trees here need a good amount of rainfall each year. Due to global warming, this biome may suffer from a decrease in precipitation. This biome is known for having the tallest trees that can live up to hundreds of years, but over the past years the amount of trees are getting reduced. Some of these trees no longer grow as much because of the lack of rainfall they've been receiving and the increase of temperature. Leaf Litter Recreational activities Hiking Camping Birdwatching Why is this biome globally important? Lily Sum Helen Zhou Janzen Camara Isabelle D. Tupas Biomes nearby Boreal Forest and Grassland End An adaptation for this animal is building complex borrows and spending the winter there. They survive by eating the storage of nuts, seeds, etc, which were collected during the summer and fall time. Chipmunks hibernate once their food supply has been used up. Chipmunk
