Title: Restoration of Forest Ecosystem Health: Western Long-needled Pines
Author: * Covington, W.W. , Sampson, R.N.
Subject: Ecological Restoration, Ponderosa pine (Pinus ponderosa)
Abstract: Semantic and philosophical confusion lies at the heart of much of the current controversy over restoration of forest ecosystem health (e.g., see Kolb et al. 1994). Nowhere are these controversies more heated than in the longneedled pine forests of western North America (Clark and Sampson 1995, Covington et al. 1994, Sampson et al. 1994, Williams et al. 1993). To some, the health of the forest is simply the health of the trees. To others, forest health implies the natural functioning of entire landscape ecosystems, including native diversity and natural disturbance regimes. In this paper we examine ecosystem health of western longneedled pine forests and draw conclusions regarding ecological restoration of this widespread forest type in an adaptive ecosystem management framework. Our paper begins by defining ecosystem health, ecosystem restoration and the concept of the evolutionary environment. Next, we present an overview of the ecological context of ecosystem health declines in ponderosa pine ecosystems. Finally, we close with a discussion of ecosystem restoration in this important forest type.
