Whitebark pine (Pinus albicaulis) plays a vital role in colonizing newly disturbed areas, providing shade for other tree species to germinate, and supplying food for a variety of birds and mammals, such as Clark’s Nutcrackers (Nucifraga columbiana) and grizzly bears (Ursus arctos horribilis). Decline of whitebark pine populations has been attributed to several factors, including white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, and fire exclusion. In 2009, the U.S. Forest Service began to install permanent plots in whitebark pine stands in Washington and Oregon as …


The Dickey Bird Scientists Take Charge: Science, Policy, And The Spotted Owl, Thomas R. Wellock Jul 2010

The Dickey Bird Scientists Take Charge: Science, Policy, And The Spotted Owl, Thomas R. Wellock

History Faculty Scholarship

In 1992, the Forest Service adopted a new operating policy, Ecosystem Management, which minimized the agency's timber production goals in favor of a more ecologically balanced view of its responsibilities. In explaining this shift, scholars have dismissed the possibility of internal reform, arguing that the Service could not change without irresistible external pressure from environmental activists and new public values supporting biodiversity. Viewing the Service's shift through the lens of the spotted owl controversy, however, demonstrates the important role agency culture played in instigating bureaucratic change. The Service's evolution stemmed from the rising influence of its scientists in policy formation. …


Conservation And Restoration Of Pine Forest Genetic Resources In México, C. Sáenz-Romero, Amy E. Snively, R. Lindig-Cisneros Jan 2003

Conservation And Restoration Of Pine Forest Genetic Resources In México, C. Sáenz-Romero, Amy E. Snively, R. Lindig-Cisneros

Student Published Works

Deforestation rates in México are about 670,000 ha/year. This threatens the richness of forest genetic resources in México, causing the disappearance of locally adapted populations and rare and endangered pine species. México is one of the six megadiverse countries in the world, with half of the world’s Pinus species. Pinus is one of the most economically and ecologically important forest genera in México. We suggest that delineation of seed zones and the establishment of a network of Forest Genetic Resource Conservation Units (FGRCUs), linked with forest management and ecological restoration programs will protect this valuable resource. We estimate that FGRCUs …
