“Empirically informed Bayesian modeling, fueled by large monitoring datasets that accumulate over time and that are underpinned by a robust survey design (e.g., our NABat spatially balanced master sample) provides a powerful and flexible foundation for building an adaptive, evidence‐based conservation information system. The long‐standing logistical challenges associated with studying bats that preclude directly estimating bat population sizes and demographic rates require the kinds of solutions that we demonstrate and discuss.”

“This study was designed to establish pika presence in a new location, determine distribution within the surveyed area, and evaluate influences of elevation, vegetation, lava complexity, and distance to habitat edge on pika site occupancy… Pika were two times more likely to occur with increasing elevation, although they were found at all elevations in the study area. This study expands the known distribution of the species and provides additional evidence for persistence in nonalpine habitats. Results partially support the predictive occupancy model developed for pika at Craters of the Moon National Monument, another lava environment.”

“We first encountered ventenata in 2014 in the John Day Fossil Beds National Monument, a low-elevation steppe protected area in central Oregon... Ventenata infestation increased within our 4674 ha monitored area from 21 ha (95% CI 3-106) in 2016 to 138 ha (95% CI 31-265 ha) in 2018, and declined to 63 ha (95% CI 13-119 ha) in 2019, representing a cumulative increase of 300% over the four year period...Our observations contribute to the growing evidence that ventenata poses a greater threat to low-elevation sagebrush ecosystems than previously recognized. It also illustrates the kinds of external stressors that are impacting sagebrush steppe protected areas and the need for continued early detection and rapid response measures, as well as long-term monitoring of invasions and response effectiveness.”
