The northern spotted owl (Strix occidentalis caurina) inhabits older coniferous forests in the Pacific Northwest and has been at center of forest management issues this region. immediate threats to federally listed species include habitat loss competition with barred owls varia), which invaded from eastern North America. We conducted a prospective meta-analysis assess population trends factors affecting those using 26 years survey capture-recapture data 11 study areas across owls' geographic...
We conducted a range-wide investigation of the dynamics site-level reproductive rate northern spotted owls using survey data from 11 study areas across subspecies geographic range collected during 1993-2018. Our analytical approach accounted for imperfect detection owl pairs and misclassification successful reproduction (i.e., at least one young fledged) contributed further insights into population ecology dynamics. Both nondetection state were important, especially because factors affecting...
Abstract There is growing interest in working with beavers ( Castor canadensis and fiber ) to restore maintain ecosystem function, improve hydrologic conditions build climate resiliency freshwater ecosystems. Beaver translocation into historically occupied but degraded systems has been increasingly applied as a restoration practice over the last two decades. Knowledge of beaver distributions on landscape critical understanding where when translocations may be effective. However, current...
