1 Temperate Rainforest Victoria Neufeld

2 Location of Temperate Rainforests
Major locations of temperate rainforest include the pacific coast of North America, and parts of southern South America.

3 Climate Temperate rainforests have four distinct seasons. Precipitation is high while temperatures are mild. The minimum winter temperature is -12℃ and the annual precipitation is between 750 and 2000 mm.

4 Winter During the winter, plants create a sugar solution so that water does not freeze in the stem, helping the plant survive through the winter. This preserves the plant until spring.

5 Spring Spring is when plants get rid of the sugar solution and new leaves grow on trees in order for both to begin the process of photosynthesis again.

6 Summer Summer in the temperate rainforest is dry and foggy.

7 Autumn The leaves of deciduous trees change colour in autumn because the trees stop producing chlorophyll, the substance that makes tree leaves green.

8 Benefits of a Mild Climate
The mild weather of the temperate rainforest makes for a longer growing season. This means enough crops can be harvested for food during the colder months.

9 Soil Type Decaying matter and fallen leaves and needles from trees on the forest floor break down into humus, releasing nutrients for plant growth. These nutrients create a black or dark brown coloured fertile soil. The type soil that forms in the temperate rainforest is called pedalfer soil.

10 Biomass Since the climate of a temperate rainforest is milder than that of a tropical rainforest, it experiences less biodiversity. However, this biome has the most biomass out of all the biomes. Biomass is the total mass of organisms in a given area % of the biomass in this biome exists in the decaying matter.

11 Benefits of Large Biomass
A large biomass provides good chances of regeneration after clear cutting

12 Plant Life and Adaptations
Temperate Rainforests contain mainly coniferous trees including western red cedar, douglas fir, and hemlock. However, it is also home to some deciduous trees such as maple, chestnut, poplar, and oak. Trees are able to grow very tall because of high amounts of precipitation.

13 Cathedral Grove Cathedral Grove is home to some of the widest and tallest trees in British Columbia.

14 Plant Life and Adaptations
Trees in this biome grow very large leaves to soak up as much sunlight as possible.

15 Plant Life and Adaptations
Trees produce sap during the winter to keep their roots from freezing. In the spring the sap can be tapped to make syrup and is then used as energy to start growing again.

16 Plant Life and Adaptations
Besides the pain it brings you when you touch it, Stinging Nettle has many different uses. It can be used for medicine, young leaves can be eaten raw with caution or cooked (an excellent source of vitamin B, proteins, and iron. It can also be used to make teas which act as a preventative against allergies.

17 Plant Life and Adaptations
The outer bark on trees in temperate rainforests protects the tree from insects and insulates the tree from extreme weather conditions.

18 Plant Life and Adaptations
Indian Paintbrush is a recognized by its bright red, clover-like flowers.

19 Plant Life and Adaptations
The salmonberry is a relative of the blackberry and raspberry. It produces berries in the spring that appear to be orange raspberries. Both the berry and the shoot are edible.

20 Plant Life and Adaptations
There are many epiphytes in a temperate rainforest. An epiphyte is a plant that grows on another plant but is not parasitic. Epiphytes grow on higher plants in order to reach more sunlight. Examples of these in a temperate rainforests are mosses, ferns, and lichens.

21 Vegetation Layers and Seasons
The temperate rainforest has five layers in its structure. They are tree stratum, small tree or sapling, shrub, herb, and forest floor.

22 Tree Stratum The tree stratum is approximately metres high and contains trees such as oak, maple, walnut, and hickory. This zone receives the most sunlight out of all the layers.

23 2. Small Tree and Sapling The small tree and sapling zone contains not only young trees of the same species of those in the tree stratum, but also species exclusive to this zone. A few of these are dogwood, sourwood, and shadbush.

24 3. Shrub The next layer is called the shrub layer. This zone contains species such as rhododendron, azaleas, and huckleberries.

25 4. Herb This layer includes short, herbal plants as well as other small plants.

26 5. Forest Floor On the forest floor there are many different species. Some of which include mosses, lichens, mushrooms, nursing logs, fallen leaves, needles, and branches. This layer is always damp and shaded.

27 Food Web The food web of temperate rainforests is generalized, this means that one predator can and will eat many different preys.

28 Wildlife and Adaptations
The banana slug is the second largest slug in the world. It is bright yellow in colour and sometimes has spots that are brown, green, or black spots. The slime on their bellies helps protect them from sharp objects. It helps with the decomposition and the nutrient cycles where it lives by eating decomposing organic matter.

29 Wildlife and Adaptations
The cougar is the second largest cat in the New World. Its diet is a broad one. They will eat anything they can find from moose to porcupines to snails and even other cougars.

30 Wildlife and Adaptations
Raccoons have needed to broaden their diet because humans are continuously overtaking their territory. Their hand-like paws give them the ability to grasp various objects such as trash can lids.

31 Wildlife and Adaptations
Each of a black bears eyes can see the world with two completely separate pictures. This is called monocular vision,it allows the bear more peripheral vision to scan more easily for prey.

32 Wildlife and Adaptations
White-tailed deer have brown, soft fur to keep them warm during the winter. Their antlers help protect them from other predators. Deer are active at all times of the day.
