Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender Oct 2009

Survival And Productivity Of A Low-Density Black Bear Population In Rocky Mountain National Park, Colorado, Roger A. Baldwin, Louis C. Bender

Human–Wildlife Interactions

Rocky Mountain National Park (RMNP) has supported a small black bear (Ursus americanus) population of low productivity. Increased visitor use of the park and development around its periphery could lead to a reduction in population viability of RMNP’s bear population or could increase the potential for human–bear conflict. Therefore, we investigated contemporary survival and productivity parameters for RMNP’s black bear population from 2003 to 2006 and compared these values to historic levels (1984–1991) and population means throughout the western United States to clarify the current status of RMNP’s bear population. The contemporary black bear population showed signs of …

Estimating Deer Abundance In Suburban Areas With Infrared-Triggered Cameras, Paul D. Curtis, Bazartseren Boldgiv, Peter M. Mattison, Jason R. Boulanger Apr 2009

Estimating Deer Abundance In Suburban Areas With Infrared-Triggered Cameras, Paul D. Curtis, Bazartseren Boldgiv, Peter M. Mattison, Jason R. Boulanger

Human–Wildlife Interactions

Interactions between humans and white-tailed deer (Odocoileus virginianus) have become common, often resulting in management actions to mitigate negative impacts. Changes in population size are generally used to judge management actions. We examined deer population estimation techniques during 2 mark-resighting experiments in a woodland-grassland habitat in central New York State and in a suburban area. We compared program NOREMARK, Lincoln-Peterson estimates, and Jacobson’s (1997) buck:doe ratios (BDR) for estimating deer abundance. In the first field trial, we sought to validate the camera survey methods and computer applications. We used infrared-triggered cameras (IRCs) to survey a white-tailed deer population …


Home Range And Habitat Use Of Feral Hogs In Congaree National Park, South Carolina, Brad A. Friebel, Patrick G. R. Jodice Apr 2009

Home Range And Habitat Use Of Feral Hogs In Congaree National Park, South Carolina, Brad A. Friebel, Patrick G. R. Jodice

Human–Wildlife Interactions

Feral hogs (Sus scrofa) are a widespread exotic species that currently occur in most states within the United States and are common throughout the southeastern United States. We radio-collared and tracked feral hogs from April 2005 to November 2006 in Congaree National Park (CNP), South Carolina, USA. The CNP is one of the largest and most intact tracts of old-growth, bottomland hardwood forest remaining in the United States. We measured home range size and determined habitat use for male and female hogs. The mean (± SE) home range sizes for male hogs (n = 7) and female hogs …
