Forest and Rangeland Ecosystem Science Center

Home

Scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse expertise to answer scientific questions shaped by the environments of the western United States. We collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide.

Invader Removal Halts Long-term Population Declines of Northern Spotted Owls

Invasive species can cause extinctions of native species and widespread biodiversity loss. Invader removal is a common management response, but the use of long-term field experiments to test the effectiveness of removals in benefitting impacted native species is rare.

Species Interactions Shape Increasing Rates of Breeding Dispersal of Northern Spotted Owls

Recent evidence suggests that frequency of breeding dispersal – the movement from one breeding territory to another – may be increasing in northern spotted owl populations, which could have consequences on population dynamics of this declining species.

Enhanced Between-Site Biosecurity to Minimize Herpetofaunal Disease-Causing Pathogen Transmission

There is increasing evidence for the role humans may play in the transport and transmission of herpetofaunal pathogens.

Intraspecific variation mediates density dependence in a genetically diverse plant species

Interactions between neighboring plants are critical for biodiversity maintenance in plant populations and communities. Intraspecific trait variation and genome duplication are common in plant species and can drive eco-evolutionary dynamics through genotype-mediated plant–plant interactions. However, few studies have examined how species-wide...

Invader removal triggers competitive release in a threatened avian predator

Invasive species can cause extinctions of native species and widespread biodiversity loss. Invader removal is a common management response, but the use of long-term field experiments to characterize effectiveness of removals in benefitting impacted native species is rare. We used a large-scale removal experiment to investigate the demographic...

Eagles enter rotor-swept zones of wind turbines at rates that vary per turbine

There is increasing pressure on wind energy facilities to manage or mitigate for wildlife collisions. However, little information exists regarding spatial and temporal variation in collision rates, meaning that mitigation is most often a blanket prescription. To address this knowledge gap, we evaluated variation among turbines and months in an...
