Differences in scientific approach between silviculture and ecosystem studies were made deeper and wider by a growing battle that swirled around the remaining stands of old-growth forest in the Douglas fir region. The flash point of the battle was the northern spotted owl (fig. ).Cited by: 3.
Tree ages are also variable in old-growth Douglas-fir for-ests in the western Cascades (Franklin and Waring ; Means ). For example, Means () found two dry-site Douglas-fir stands with trees ranging in age from 80 to years. He concluded that the broad range of ages was the result of periodic fires that killed only some of the. Following the completion of the project, Definition and Inventory of Old Growth Forests on DNR-Managed State Lands, we produced two guides for identifying old trees and forests in Washington: Identifying Mature and Old Forests in Western Washington and Identifying Old Trees and Forests in Eastern Washington, both written by Robert Van Pelt, PhD.
Bible's big Douglas fir, and the old-growth acres around it, survived only because one of those early researchers, a Yale Forest School graduate named Thornton Taft Munger, insisted on. We used tree-ring records to reconstruct the stand initiation of an old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand in the western Cascade Range of southern Washington. All tree-ring samples were prepared and crossdated. Following a stand-replacing fire, the stand initiation period lasted from to , with gradual filling-in of growing space .

An old-growth forest — also termed primary forest, virgin forest, primeval forest, late seral forest, or forest primeval — is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community.

The study provides a basis for defining and taking inventory of old-growth conditions as well as for managing the natural diversity of old-growth and earlier successional Douglas-fir forests in. An inventory rule is derived for a general model.
For plausable functional forms this rule implies and explicit solution for the optimal inventory of old-growth forest. The specific model is estimated for the Douglas fir region of western Washington and Oregon, where perhaps percent of the pre-logging stock of old-growth remains.
