Evaluating areas of high conservation value in western Oregon with a decision-support model

Abstract: The Northwest Forest Plan was implemented in 1994 to protect habitat for species associated with old-growth forests, including Northern Spotted Owls (Strix occidentailis caurina) in . Nevertheless, Resumen: El Plan Forestal Noroccidental fue implementado en 1994 para proteger el hábitat para especies asociadas con bosques maduros, incluyendo Strix occidentailis caurina en Washington, Oregon y norte de California (E. U. A.). Sin embargo, datos de monitoreo durante 10 años indicanéxito mixto en el logro de las metas ecológicas del plan. Utilizamos el modelo de respaldo a la toma de decisiones para el manejo de ecosistemas para evaluar hábitats terrestres y acuáticos en el paisaje con base en los objetivos ecológicos de

Effect of Human Disturbance on Small Mammal Communities in Itasca State Park, Minnesota

We determined effects of different levels of human disturbance on small mammal richness and relative abundance from live-trapping data obtained in Itasca State Park in northwestern Minnesota. We developed a quantitative measure of human disturbance based on disturbance units and trapped small mammals on three study sites, each reflecting a different level of disturbance. Our data revealed that small mammal diversity decreased with increasing human disturbance. Amount of ground cover and litter depth also appeared to be important in explaining differences in the demographic patterns of small mammals among sites
