17. What Is It Like In The Foothills? ClimateWeather is always changing! Rain falls during Spring and Fall, and some snow falls in Winter. Temperature Geography Soils Soils are sandy and have lots of broken up rock left there from glaciers Summer temperatures can be HOT, up to 100 degrees, and winters can be cold, down to 20 degrees. BRRR! Located just upslope from the plains. They are smaller than mountains, but taller than most hills!

24. What Is It Like In The Montane? Climate Temperature Geography Soils Snow falls in late fall and winter, thunderstorms in summer, more rain than foothills. Warmer than alpine. Stays near freezing (24-32 F) in the winter, warm in the summer (70-78 F) 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.

25. How Tall Are The Trees In The Montane? Plains Montane Alpine Foothills Riparian

26. What kinds of plants grow in the Montane? ?

27. Douglas 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

28. Lodgepole Pine

29. Aspen 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. Grows well after fire

30. Indian Paintbrush Columbine State flower of Colorado!

31. Subalpine Life Zone

32. Foothills 5,500 – 8,000 ft. Plains 3,500 – 5,500 ft. Montane 8,000 – 10,000 ft. Subalpine 10,000 – 11,500 ft. Riparian Alpine 11,500 +ft. Subalpine Life Zone

33. What Is It Like In The Subalpine? Climate Temperature Geography Soils Winter is LONG and summer is SHORT. Snow begins in early fall and stays until early summer in the shade of the forest. Stays below freezing (18-24 F) in the winter, a little cooler than the Montane Zone in the summer (62-78 F) 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.

34. What kinds of plants grow in the Subalpine? ?

35. Lodgepole Pine Limber Pine Engelmann Spruce Subalpine Fir There are 4 different trees in the Subalpine What adaptation do all these trees have in common?

38. What Is It Like In The Alpine? Climate Temperature Geography Soils Coldest Life Zone with VERY strong winds. 12-20 inches of snow falls per year. Snow gets moved around by the winds. Around freezing every night of the year. Highest life zone. Located above subalpine and above treeline. Very shallow soils. Soils are mostly made up of rocks and plant roots.

39. What kinds of plants grow in the Alpine? ?

40. Plants 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!

41. What kinds of animals live in the Alpine? ?

42. Picas are farmers! Yellow-bellied Marmot

43. Ptarmagins change colors like the snowshoe rabbits. Who are these ptarmagins hiding from?

44. Alpine Food Web

46. Foothills 5,500 – 8,000 ft. Plains 3,500 – 5,500 ft. Montane 8,000 – 10,000 ft. Subalpine 10,000 – 11,500 ft. Riparian Alpine 11,500 +ft. Riparian Life Zone

47. What Is It Like In The Riparian? Climate Temperature Geography Soils Usually cooler than the surrounding landscape. Similar to the surrounding landscape. Located around running waters, usually in low areas on the landscape. 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.
