Subalpine Life Zone

Treeline is not an abrupt transition in most areas. Rather, as you move up towards and above 11,000 feet, you will notice the spruces and firs becoming noticeably smaller, until they start to assume bush form. This stunted forest is often called the krummholz. The birds in this habitat tend to be a mix of spruce-fir and tundra birds, but the dominant species is definitely White-crowned Sparrow.
