Roosevelt elk (Cervus canadensis roosevelti) in northern California utilize a wide range of habitat types, resulting in variability in the success of population monitoring techniques. Within the North Coast Elk Management Unit, Roosevelt elk are found across a mixture of public and privately owned lands. For frequently visible elk along the Highway 101 corridor, road surveys and free-range darting have proven to be successful strategies for population monitoring. While these techniques are effective, non-invasive sampling techniques such as fecal DNA analysis and remote cameras are growing in popularity due to their success with highly mobile species such as elk. In this study, two estimates of abundance utilizing a spatial capture-recapture analysis and a time-to-event model will be compared for an elk population in Maple Creek, California. With expanding populations and increased human-wildlife conflict, an accurate estimate of abundance provides important information for effective management.
