How Climate Change Effects Elk, Plants and Birds

Science Daily reports on a recent study by the U.S. Geological Survey and University of Montana that shows the impact of a decreasing snowpack in the Arizona Mountains on plants and animals.  Here are some of their findings that show an ecological cascade of events:

  • Climate chnage leads to a decreased snowpack
  • Decreased snowpack leads to winter access to high elevation trees
  • Elk browse trees at higher elevations
  • Over browsing leads to decline in deciduous trees
  • Decline in deciduous trees leads to decreased habitat for birds
  • Decreased habitat and bird population lead to increased predation on remaining bird nests

And maybe the top of the list could be human behaviors causing climate change?
