3
Bobcat – Lynx rufus
4
Objectives 1.What is the maximum carrying capacity for bobcats in Vermont? 2.How will carrying capacity change between 2000 and 2050 given housing/road development?
5
Methods 1.Home range data 2.Habitat suitability map 3.Estimate carrying capacity
6
Maximum clique analysis
7
4.Habitat suitability map in 2050 given projected housing and road development. 5.Estimated carrying capacity.

Results Radio-collared 4 females and 10 males. Shrub, deciduous, mixed, wetland, evergreen, roads. 2000 Females: 835 (±120) Males:316 (±145) Total: 1150 2050 Females: 804 (±117) Males: 367 (±141) Total: 1171

Conclusions First statewide estimates of bobcat carrying capacity. First statewide estimates of bobcat carrying capacity. Urban development and roads exerts little change. Urban development and roads exerts little change. Caveats: data, modeling, and future projections. Caveats: data, modeling, and future projections.
