Conservation Northwest

2016 CWMP Field Season Report

Conservation Northwest protects and connects old-growth forests and other wild areas from the Washington Coast to the British Columbia Rockies, vital to a healthy future for us, our children, and wildlife. Since 1989, Conservation Northwest has worke

The vicinity camera captures detections within the general area and the run-pole camera detects animals on the run-pole. For this reason, duplicate events are deleted prior to updating our database to obtain a more accurate understanding of detection rate and species detected, without doubling detection events (Table 8). The two installations at Joe Lake did not have run-poles established at the sites and so had one camera each. One of the Skyline cameras was not activated upon installation and the site was removed early on in the season due to lack of team leads. The Summer Blossom Ridge remains on the landscape from 2015 and no data has been collected. Wolverine and gray wolf, both level one species, were detected at wolverine-targeted survey areas this season. Wolverines were detected at Union Gap and Chiwawa, and a gray wolf was detected at Chiwaukum. A new wolverine detection occurred at Chiwawa with two wolverine detection events which were determined to be the same individual. The high rates of wolverine detections at Union Gap spanned over two days in March, five days in April, and one day in September. Unfortunately, genetic samples that were collected from Union Gap were unable to determine whether these were wolverines with existing DNA profiles or new individuals. However, based on unique chest blaze patterns, at least two distinct individuals were observed (Appendix VI). Genetic samples obtained in the field during the 2016 monitoring season and processed in the lab did not return results of gender or individual ID. This problem is associated with the small sample size of cells related to non-invasive genetic sampling (hair samples compared to blood or tissue) and the degradation of genetic samples from the elements. In areas with high detection rates of target species, like the wolverine, we will be advising volunteers to visit the site more frequently and retrieve the samples as soon as they can, and, if they are wet, to put them in desiccant
