Brown Bear Monitoring in the Arctic Network of National Parklands

Delisle Z. Brown Bear Monitoring in the Arctic Network of National Parklands. 2009. National Park Service

The purpose of this project is to develop and implement a population monitoring protocol that has statistical validity, is cost-effective, and can be implemented across the network. Managing brown bear populations presents biological, cultural, and legal challenges for park managers. Baseline ecological data are lacking for brown bear populations in ARCN despite increasing harvest and viewing demands from the public. Brown bear abundance may be a parameter that can be estimated across the network if a logistically simpler, statistically rigorous, and cost effective estimator of brown bear abundance can be developed and implemented often (i.e., every 3-5 years in each sampling area). This technique will rely more on direct, aerial observation of bears during one sampling period which could make it more cost-effective than the current line-transect technique used in Alaska which is more expensive and requires multiple years of effort to obtain one estimate.
