Part Iv Madrone in Habitat Restoration
نویسنده
چکیده
Pacific madrone (Arbutus menziesii) is in decline in urban areas of the Pacific Northwest. Maintaining significant populations of this species requires development of restoration techniques for urban environments. My research consists of investigating the effects of light, irrigation and native soil on the establishment of Pacific madrone. I transplanted 104 one year madrone seedlings into an urban site that has sufficient variation in light environments to provide full and partial sun exposure treatments. Nested treatments of native soil addition and irrigation are imposed within the separate light treatments. During the experimental period, I measured for overall plant growth and biomass accumulation, carbon dioxide (CO2) uptake and water stress levels. Experimental results are useful in habitat restoration and revegetation applications for Pacific madrone.

Use of Arbutus menziesii by Cavity-nesting Birds
As part of a larger study of wildlife habitat associations in Douglas-fir (Pseudotsuga menziesii) forests of northwestern California, I recorded characteristics of nest sites used by 16 species of cavity-nesting birds. Pacific madrone (Arbutus menziesii) contributed only 8% of the basal area of the stands I studied, but 24% of all cavity nests were in madrone. Although nests were distributed am...

This paper reviews ecological interactions of birds with Pacific madrone (Arbutus menziesii). Results from a tree inventory in the Magnolia area during 1994–95 and a literature search are summarized. We surveyed 126 trees and found 2 Northern flicker (Colaptes auratus) cavity nests and 35 cup nests. American Crows (Corvus brachyrhynchos) occupied the cup nests. Madrone is a substrate for nestin...
