Saptial pattern of meadows and shrubs in a landslide area and their roles in creating habitat for bird and mammal species in the central western Cascade Range, U. S. A.

Abstract

This study aims to examine the effects of landslide on spatial distribution of non-forested openings and their roles in creating habitat for bird and mammal species in the central western Cascade Range, Oregon. The results of GIS analysis of vegetation and landforms indicate that distribution of non-forested openings is related to micro-landforms that formed inside a landslide area. Preliminary observations indicate that shrubs dominated by Acer circinatum and Alnus crispa ssp. sinuate provide habitat for wildlife.
