Estimating marten Martes americana population size using hair capture and genetic tagging
We tested non‐invasive genetic methods for estimating the abundance of marten Martes americana using baited glue‐patch traps to pull hair samples from individual animals. We divided our 800–km 2 study area into 3 × 3 km cells and put one hair trap in each cell. We trapped 309 sites for an average of...

We believe hair sampling and genetic analysis could be used to measure population distribution, trend and size for marten, and perhaps also for other carnivores.
