The hump-shaped relationship that predicts highest species richness (species/unit area) at intermediate levels of productivity was examined for woody plants across the Pacific and Inland Northwest of the U.S. Many studie ...

Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian ov ...

Since the 1990s the U.S. and especially the Western U.S. have experienced more intense and costly fires. To help address this problem government agencies are increasingly looking at homeowners in fire-prone landscapes to ...

Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is ...

This research analyzes how family forest owners conceptualize biodiversity in one high-conservation value area of oak woodland in the Willamette Valley of Western Oregon. Oregon white oak (Quercus garyanna) woodland, one ...

The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem st ...

Throughout the 20th century, windthrow has affected forests in the Bull Run watershed, a 26,500 ha basin that is the principal water source for the city of Portland, Oregon. Windthrow from storms in 1973 and 1983 was map ...

Old-growth dry-mixed conifer forests are valued as habitats for late seral forest species, for the ecosystem services and landscape diversity they provide, and for their aesthetic appeal. The structure of these forests ...

A field study was established to explore stand structure and development patterns of mature, mixed-species forests in the Interior Cedar-Hemlock (ICH) zone: moist cold subzone of northwestern British Columbia. The spec ...
