Bobcats are making a comeback in Rhode Island.
At one one point they were virtually nonexistent in the state, but in recent decades, bobcat sightings are becoming more common. And now, the University of Rhode Island partnered with state environmental managers and local nonprofits to launch the Rhode Island Bobcat Project, which is intended to promote bobcat conservation and learn more about how they contribute to Rhode Island’s ecosystem.
Morning host Luis Hernandez spoke with Kathleen Carroll, assistant professor of applied quantitative ecology at URI, and Christopher Hickling, a Ph.D. student at URI in natural resources science, about what the project hopes to accomplish.
Interview highlights
On the purpose of the Rhode Island Bobcat Project
Kathleen Carroll: We have been thinking a lot about different carnivores across the landscape here. Rhode Island is a really unique system because we have so many people and we’re seeing big changes in our carnivore communities.
There was a publication that came out from a postdoc in my lab from her PhD, Laken Ganoe with the (Rhode Island Department of Environmental Management), and she found that almost every carnivore species – fisher, gray fox, red fox – are all declining, but that coyotes and bobcats are not. And so there’s a lot of questions that we have about why some of the species that are iconic New England species are not doing well when bobcats seem to be doing very well and apparently are on the rise across the state.
On the difficulty of studying bobcat populations in the wild
Christopher Hickling: Bobcats are cautious and smart, but they’re also curious. They’re difficult to trap, and they never really exist in high population densities. There’s never going to be an overabundance of bobcats in one location. So that means you need to cover a large geographic area with your efforts. It requires a lot of time and commitment to be able to achieve a sample size large enough to learn something.
We track them in a cage-trap, humanely. And we anesthetize them for about 30 to 45 minutes. We take a bunch of biological samples and measurements, and then we fit them with a GPS collar, which they wear for just over a year. And that sends us their location every couple of hours via satellite to our computers, and that’s how we monitor the places they go.
On the findings of the initial leg of the Bobcat Project
Carroll: We wrapped up in September having 320 cameras at 160 sites across Rhode Island on public land, and we’re definitely seeing cats at a lot of locations.
We also have started a citizen science project where we have over 600 reports of people submitting sightings of bobcats; we’re seeing that there’s definitely quite a few cats across Rhode Island. We’re seeing a lot of cats in Narragansett. So with that, paired with Chris’s field experience, we’re getting a really good sense of where we should focus our efforts.
On how bobcats contribute to the ecological health of Rhode Island
Hickling: In a bunch of different ways.
There’s lots of studies looking at top carnivores and how they influence ecosystems. And so one of the big ones is disease-controlling rodent populations. Bobcats, in addition with other carnivores who are kind of occupying this role of top carnivores in our eastern forest, are providing all these benefits. And there are studies that show that top carnivores influence things as far reaching as erosion and helping promote diverse native plant communities, creating biodiverse microbial environments at kill sites. There are lots of different studies on the importance of carnivores and bobcats – because we don’t have pumas or wolves and bigger apex predators here in Rhode Island – bobcats and other carnivores are helping the ecosystem by sort of occupying that role.
