Weather is always changing! Rain falls during
Spring and Fall, and some snow falls in Winter.
Temperature
Summer temperatures can be HOT, up to 100
degrees, and winters can be cold, down to 20
degrees. BRRR!

smaller than mountains, but taller than most
hills!
Soils
Soils are sandy and have lots of broken up rock
left there from glaciers

30What kinds of animals live in the Foothills?
?
31Elk
Elk live mostly at higher elevations, but in the
winter they can move into the foothills
32Mule Deer
There are many deer in the foothills. This is
a mule deer.
How can you can tell?
By its big ears!

Fox
Coyote
Raccoons
These animals can adapt very well to human
environments. That is why you see them living
near cities.
34Mountain Lion
Mountain lions are important predators in the
food web. They hunt deer and small elk as well as
other small animals. Mountain lions have a
territory of up to 500 sq. miles! Do you know why
their territory is so big? They are losing their
homes because so many people are building houses
in the foothills.
35Great Horned Owl
Ladybugs eat other bugs that kill plants.
They help keep the foothills healthy!

36Montane Life Zone

38What Is It Like In The Montane?
Snow falls in late fall and winter, thunderstorms
in summer, more rain than foothills. Warmer than
alpine.
Climate
Temperature
Stays near freezing (24-32 F) in the winter, warm
in the summer (70-78 F)
Geography
Located between foothills and subalpine. This
zone supports many types of plant and animal
habitats.
Deep soils in flat meadows help grasses and
shrubs grow. Trees grow better in less wet, more
rocky soils on the slopes of the valleys.

41Douglas Fir
- Found in wet upper montane zone
- Flat needles, cones have mouse tails
- Rough Bark
- Strong, Hard Wood Good for Construction
- Bears like to scrape the bark and eat sap
42Lodgepole Pine
43Aspen Trees
- Trees lose their leaves in the fall
- Very Fertile Soils Beneath Aspen
- Leaves quake or tremble in the wind
- Most trees in an area are from one root.

52What Is It Like In The Subalpine?
Winter is LONG and summer is SHORT. Snow begins
in early fall and stays until early summer in the
shade of the forest.
Climate
Temperature
Stays below freezing (18-24 F) in the winter, a
little cooler than the Montane Zone in the summer
(62-78 F)
Geography
Located between montane and alpine. This zone is
mostly forested with some meadows.
Deep soils in flat meadows help grasses and
shrubs grow. Trees grow better in less wet, more
rocky soils on the slopes of the valleys.

55What kinds of animals live in the Subalpine?
?
56Chipmunks

64What Is It Like In The Alpine?
Coldest Life Zone with VERY strong winds. 12-20
inches of snow falls per year. Snow gets moved
around by the winds.
Climate
Temperature
Around freezing every night of the year.
Geography
Highest life zone. Located above subalpine and
above treeline.
Soils
Very shallow soils. Soils are mostly made up of
rocks and plant roots.
65What kinds of plants grow in the Alpine?
?
66Plants of the Alpine zone are small in size and
hug the ground.
This is so they are protected from the cold
temperatures, snow and strong winds!
67What kinds of animals live in the Alpine?
?
68Picas are farmers!
Yellow-bellied Marmot
69Ptarmagins change colors like the snowshoe
rabbits.

73What Is It Like In The Riparian?
Similar to the surrounding landscape.
Climate
Temperature
Usually cooler than the surrounding landscape.
Geography
Located around running waters, usually in low
areas on the landscape.
Soils
Mostly composed of sand and gravel that is
created by tumbling rocks in the water. Near the
banks, the soil is usually wet and will support
plants that like wet soils.

83Beaver the ecosystem engineer
It lives in lodges in streams and ponds with its
mate for life and 3-4 kits. It is the largest
rodent in North America. It can use its big tail
as a rudder while swimming. It has really long,
dark orange front teeth that help gnaw down
trees. When Europeans first settled they killed
beavers for their fur.
