DURHAM, N.H. (AP) — The New Hampshire Fish and Game Department and the University of New Hampshire need volunteers to help count bobcats in the southern part of the state.

Pat Tate, the furbearer biologist for the department, says sightings of the elusive cats have increased over the past two decades so scientists want to get a better handle on how many animals are here. The research is part of a multi-year bobcat study.

Volunteers must have their own trail camera, preferably no more than 5 years old, and be willing to monitor for bobcats following specific rules. The areas to be monitored are around Bradford, Swanzey and Deering.

Training started this week. Counts will continue through December.

Interested volunteers should contact the Fish and Game Department or university.
