Vegetation in Marin




Vegetation

Marin County is home to a few different types of ecosystems.  The most common one, which is also present in Kentfied, is the woodland ecosystem.  There are still many trees in Kentfield and used to be even more.  Before modern development Kentfield was covered in trees, with a few swamplands and grasslands in valleys. 

To test the soil in Marin I took a hike up the hill I live on to find soil untouched by humans.  The area was dense in trees and shrubs.  I began to dig, but found it very difficult to go any further after only about half a foot.  There were so many tree roots that the soil was hard to surpass.  I picked up and felt the soil I had dug up, and it was very dry and thin.  It feel through my fingers easily.  There were many types of materials in it, including roots, small rocks, clay and dirt.  It did not look very healthy because of how dry it was, but because of the abundant plant life around the area I drew the conclusion that it was.
