This page dedicated to the project “Using multiple data sources to develop management strategies for the recovering bobcat (Lynx rufus) population in Ohio” funded by the Ohio Department of Natural Resources ($245,000).

Given the proposed trapping season, our work has been in the news here, here, here, and here.

Project team:

  • Dr. Viorel Popescu, PI
  • Heidi Bencin, MSc student (defense date: December 2018)
  • Marissa Dyck, PhD student (starting August 2018)
  • Dr. Suzanne Prange, Adjunct Faculty, Ohio University
  • Dr. Steve Spear, The Wilds
  • Field crew: Devon Cottrill, Julia Golias, Ryan Brown, Connor Hall

Project objectives:

(1) Determine predictors of road mortality, and the overall risk of road mortality for the bobcat population in Ohio;

(2) Characterize the rate of expansion of the bobcat population in Ohio, evaluate current occupied range, and predict future areas for expansion,

(3) Identify source and sink areas in Ohio to inform management via trapping;

(4) Evaluate bobcat density in two core area in S and SE Ohio; and

(5) Integrate existing and new information to predict population trajectories and acceptable trapping levels using a Spatial Population Viability Analysis framework.

Progress to date (April 2018):

  • June 2017 – April 2018: evaluating habitat use by bobcats and other carnivores using camera trapping on public lands in SE Ohio (63 sites)
  • June – November 2017: evaluating density of bobcats from hair DNA; 180 snares resulted in 600+ hair samples, currently being analyzed in collaboration with Dr. Steve Spear at The Wilds


  • January – April 2018: road mortality risk analysis using road mortality data and GPS telemetry data (Heidi Bencin thesis)
  • January – April 2018: spatial relations between verified sightings data and road mortality data (undergraduate student Ryan Brown)
