In this lab, you’ll explore the behavior of the upper treeline – where the forested zone gives way to the alpine zone. As Gard notes, “it’s a rather thick line.” Based on Haberdasher’s article, we’ll look at the transition between solid forest, krummholz, and alpine tundra in several sites around the world. We will do the following:
Explore four case studies to get a sense of what alpine treeline look like in different contexts.
Identify mountain tree lines around the world using Google Earth and collect latitude, treeline elevation, and other ancillary data from these locations.
Make and analyze a scatter plot of global treeline elevations using the data set compiled by the entire class.
Lastly, we’ll probe Haberdasher’s descriptions of the biological processes responsible for treeline.
Haberdasher’s reading is essential for this lab – please read it if you haven’t already.
