Domestic goats, Capra hircus, were intentionally introduced to numerous oceanic islands beginning in the sixteenth century. The remarkable ability of C. hircus to survive in a variety of conditions has enabled this animal to become feral and impact native ecosystems on islands throughout the world. Direct ecological impacts include consumption and trampling of native plants, leading to plant co...

—Accurate estimates of Black-backed (Picoides arcticus) and Hairy Woodpecker (P. villosus) nests and nest survival rates in post-fire landscapes provide land managers with information on the relative importance of burned forests to nesting woodpeckers. We conducted multiple-observer surveys in burned and unburned mixed coniferous forests in Oregon to identify important factors influencing detec...
Rocky Mountain spotted fever (RMSF) is a systemic infection, now known to be caused by Rickettsia rickettsii, that was not recognized until early in this century. The description of the disease, etiology, transmission, and treatment were all discovered over a 50-year period. It is probable that earlier sporadic cases were encountered but were not recognized as a distinctive disease. RMSF in con...

A system was developed which integrates optimization based management planning models using map based representations of the spatial area being analyzed. This system was designed to address the decidedly hierarchical planning environment of the USDA Fore...

Today, Forest Service fire management programs must be cost effective, while wilderness fire management objectives are aimed at recreating natural fire regimes. A cost-effectiveness analysis has been developed to compare fire management options for meeting these objec...
