Movement near CA's highwaysWhat movements have bighorn sheep lost to habitat fragmentation? We placed GPS collars on bighorn to describe how they use habitat near highways and modelled where they might go in a world without barriers.

Underpasses as wildlife corridorsDo structures designed for water flow instead of wildlife allow enough habitat connectivity? We used trail cameras to learn which species use existing underpasses & bridges along the borders of the Mojave National Preserve.

Sign surveys for bighornWhat mountain ranges currently support bighorn populations? Bighorn sheep are actually pretty hard to find. So we developed a survey that relies more on sign like pellets and bedding sites to help track bighorn distributions across the vast desert landscape.

Gene flow & connectivityWhat's new in bighorn genetics? Oregon State University has been documenting bighorn gene flow since the early 2000s. We're updating that data with new samples from Joshua Tree National Park & surrounding areas to see what's changed in recent decades.

AI training for bighornWe can learn a lot about bighorn populations and resource use by setting trail cameras at water sources. But the photos pile up quick and can be hard to keep up with! To speed up photo review we're looking into whether AI can be trained more efficiently to find bighorn.
