| Carnivores can be challenging to survey because of their low density, large home range size, and secretive behavior. The Humboldt subspecies of Pacific marten (Martes caurina humboldtensis) persists in small isolated populations in coastal California and Oregon. This Distinct Population Segment was petitioned for listing consideration under the Endangered Species Act, but denied in April 2015. The Humboldt marten subspecies is associated with dense berry-producing shrubs, which may provide shelter from potential predators. Dense shrub cover also provides survey challenges as access is difficult. We examined the cost-effectiveness of two survey methods: scat detection dogs and remote cameras paired with hair snares. We used three metrics to compare these methods: number of detections, sex ratio, and the ability to obtain extractable genetic material. Costs were similar between methods. Preliminary results suggest that remote camera surveys provided opportunities over larger geographic extents, and detections were more consistent with scat detection dogs at a fine scale. We encourage future research to consider the sex and age of detected animals, focusing on conservation relevance to the population in addition to species occurrence. |
