Madrone
Plant survey finds over 100 plant species at threatened site
 Photo: Keith Daellenbach |
In 1999 Portland State University conducted an inventory of plants on the Madrone Wall site. The area contains a Douglas-fir forest, exposed cliff faces, and soggy wetlands. These different environments yield a variety of species. The site has become known for the Pacific madrone. Uncommon in the temperate climate of Northwest Oregon these madrone trees demonstrate unique environmental conditions. The dry southern faces and the rocky terrain help this species thrive.
Although many of these plants are commonly found in Oregon they are living in a unique environment. The cliff faces and jumbled boulders provide a diverse terrain. The open space of wetlands and rock next to the forest canopy create an edge effect which is favored by many animal species.
The following list identifies the plant species found on the 44 acre site.
