Temperate Rainforest
What is The Temperate Rainforest?
The Temperate Rainforest is a small biome
along the northwest coast of Northern
California. It also includes little parts of
Southern Chile, New Zealand. The
Temperate Rainforest covers about 75
million acres of earth. 2/3 of The Temperate
Rainforests are in the Pacific Northwest.

Rain Fall in Temperate Rainforest
The temperate Rainforest receives about 60 to 200 inches
of rain per year.
There are 2 seasons in The Temperate rainforest. One
long wet season and one very short dry and humid season.
Latitude of The Temperate Rainforest
Mid- altitude between 23.5 degrees and 55 degrees South
and West.
FIVE PLANTS
1. Deer Fern (Blechum Spicant)
• Deer Fern is very common in the Temperate Rainforest. It
is native to the temperate rain forests of Western North
America, Iceland and Norway. This also grows on the floor
of the forest.
• Adaptations- The Deer Ferns grow early in the spring with
long, quick-growing leaves. This allows the plant to
absorb as much sunlight as possible before the forest
trees leaf and block the full strength of the sun.

2. Sitka Spruce (Picea Sitchensis)
• The Sitka Spruce, or Picea sitchensis, is a plant very often
associated with the temperate rain forest. The Sitka
Spruce can grow in poor soils where many other trees
can't, this is one reason why it is so successful. It is a
huge tree, growing up to 100 meters tall and 5 meters
thick.
• Adaptations- The trees have to grow larger leaves to
absorb the most light during the growing season. The bark
of trees is thicker than tropical trees to protect the inner
core during long, hard winters.

3. Giant Horsetail (Equisetum Telmateia)
• The giant horsetail lives in the temperate rain forest, and
its scientific name is Equisetum telmateia. It can grow up
to 200 cm tall.
• Adaptations- The giant horsetails biggest adaptation is it
must adapt to the moist environment.

4. Salmonberry
• Salmonberry is one of the most abundant temperate
rainforest plants. The tender spring shoots can also be
eaten, and have a sweet, almost candy-like, taste to them.
A three-foot long, straight, finger-width section of a
salmonberry branch can make a good hand drill stalk for
making friction fires.
• Adaptations- The Salmonberry grows and bloom before
shrubs and trees leaf out and cut off their sun supply.
They only bloom for a few weeks in the spring.

5. Western Red Cedar
• Western Red Cedar is a widespread tree. It has a
seemingly endless list of uses. Traditionally, the bark was
used for baskets, rope, mats, and clothing. The wood was
used for plank long houses, canoes, paddles, and many
other types of tools. A tincture can be made from the
fronds that is a topical antifungal medicine.
• Adaptations- The truck and roots have to be thicker or
they will die in the Temperate Rainforest.

FIVE HERBIVORES
1. Squirrels
Adaptations- They store large supplies of food in the
ground for later in the season.

2. Roosevelt Elk
Adaptations- They use there antlers and for defense and
mating purposes. Flat teeth for grinding. And than Sharp
hooves for defense too.
3. Douglas Squirrels
Adaptations- Curved claws for climbing, and great leaping
ability. Vocal calls used to warn animals of nearby
predators.
4. Beaver
Adaptations- They have fur to keep them warm when it
gets cold.
5. Snakes
Adaptations- They eat berries, shrubs, mushrooms, grass
and more to keep them alive.
FIVE CARNIVORES
1.Black Bears
• Black Bears are one of the main carnivores in the
Temperate Rainforest. They are usually always on a meat
diet. If they aren’t they are eating berries.
• Adaptations- The weight they gain during the summer and
fall allow them to hibernate during the winter when the
weather is cold and there is barely any food.

2. Mountain Lions
• Mountian Lions another main carnivore in the Temperate
Rainforest.
• Adaptations- They have to adapt to the climate since it is
colder and have really hard winters. While adapting they
eat a lot to gain weight so they can survive the winter.

3. Gray Fox
• The Gray Fox likes to feed on the a lot of mice and wood
rats.
• Adaptations- They like to store their food so in the winter
they don’t have to go hunt in the cold weather.

4. Bobcat
• The bobcat is a carnivore that lives in the Olympic
Peninsula. They eat mostly rodents and rabbits.
Sometimes in the winter, they will even eat deer. Bobcats
are highly adaptable and live in many other biomes.
• Adaptations- The Bobcat is very good at adapting the
climate of the biom.

5. Wolf
• Wolves mainly eat rabbits and other mammals. They are
one of the main carnivores for the Temperate Rainforest.
• Adaptations- Wolves grow thicker pelts in the fall to
protect the animals during the cold winter months.

8. Food Web

Rainforest.
Predator/Prey
-Wolf/Wild Hare
The population of the Wolf fluctuates with
the population of the hare. As the wolf
population increases the rabbit population
decreases. With the lack of the hare, the
wolves begin to die off. Once the population
of the hare increases the rise in the wolf
populaton begins.
VS
Parasitism
Parasitism in the Temperate rain
forest is when a lychee or a tick
sucks the blood out of another
animal.
Competition
The moose and elk both compete with eachother
for the shrubs and plants in the North American
Temperate Rainforest.
VS
Mutualism
The insects pollinating flowers and the flower
providing food for the insects in the form of
pollen or nectar is mutualism in the Temperate
Rainforest.
Benefits
• Some benefits of the Temperate Rainforest are they are
useful for fresh air because of all the trees. They are also
good for tourism and scientific resources.
• How we perserve it- We use the trees for wood and
decorations. We also use some of the animals for food
resources, and a lot of tourisms go there to.
Threats
• The trees that make up the temperate rainforest are huge,
and their value as timber is based on their size. With
forests elsewhere already cut, there is tremendous
pressure in temperate rainforests. Timber cutting is the
number one threat to these forests. If not done carefully,
soil erosion can happen.
Any Wetlands?
• Yes, there are a lot of swamps, lakes, and rivers in the
Temperate Rainforest.
