At what elevation is the end of the "tree line"?

4000 ft in Alaska - 13,000 in Mexico

Tree lines mark the limits of where trees can grow; they are the transition from forest to alpine habitats. As the elevation increases the sites become increasingly harsh. For example, temperatures and growing season length decrease, while precipitation, snow depth, and solar radiation increase. The high elevation pines are one of a handful of trees that commonly form tree lines in western North America.

The tallest life zone, the alpine tundra can be found at any latitude on earth. yet, the elevation that the alpine tundra begins is different depending on where you are.

For instance, on the tall Mexican Volcanoes, the treeline is much higher than anywhere in the United states. It occurs around 13,000 feet.

In Colorado, the Tundra begins around 11,500 feet. Farther north, in Alaska, the Tundra can form at only a few thousand feet elevation!

Tree lines, has more to do with cold, and how dry it is, then anything else. Of course the higher you go in elevation or latitude the colder it is.

Even on the same mountain over time it will very.

RE:

It depends on other climate factors besides elevation. In the Adirondacks where I used to go camping, I think it was around 4800 feet. On Mount Kilamanjaro (which sits on the equator), I'm sure it's much higher.

the tree, c'est finis. I know it is meant to be a translation, but english speakers understand c'est finis, and it rhymes with tree.
