A total of 155 marten hair sampling stations were deployed in 2010, including 60 in or around North Cascades National Park during the summer months. Poor success with summer sampling near I-90 and Route 2 in 2008–2009 prompted a shift to winter sampling in these regions.
Although summer sampling in North Cascades National Park did result in numerous putative marten detections (see map below) as well as some incidental black bear detections, we’ve determined that winter sampling for martens would likely be more effective in this region too—and it will thus be pursued if resources permit.
Prior to the 2010 summer sampling, we had acquired 11-locus genotypes for 36 martens across the NCE, including 14 from the I-90 region, 17 from Route 2, and 5 from Highway 20 (see map below). DNA results from 2010 summer sampling are pending from Wildlife Genetics International.
