Utilization and Management of Alder


Book Description

In the Pacific Northwest and British Columbia, red alder often grows on forest lands following natural or man-caused disturbances. Frequently ignored as a pest or weed, many alder stands have developed to the point where important utilization and management questions are being asked. It is recognized that alder is a fast growing species, and that its rapid early growth may hinder growth of conifers associated with it. It is also recognized that alder has the capability of improving soil fertility, and that it may help reduce root rot problems of conifers. These attributes pose new questions as to whether or not alder should be deliberately managed and, if so, how it should be managed and utilized.
