Vegetation Index of Western USA

43.8N 120.5W

April 24th, 2013 Category: Climate Change, Vegetation Index

USA – April 24th, 2013

This image shows the vegetation index of western USA and southwestern Canada. Green indicates a high index, while yellow and orange indicate a low index. Some model simulations of future vegetation changes in states such as Oregon indicate that high elevation areas of subalpine forest and alpine tundra as well as areas of shrubland will contract under projected future climate changes.

These projected vegetation changes would reduce critical habitat for many species. As species distributions change, the current associations of plant species may also be affected. Some model simulations indicate that the species composition of forests may already be changing and that the rate of change will increase during the 21st-century (click here for more information).
