Update on the Fisher Den Box Project

Fisher_denbox
Can’t get enough fisher footage ? HCTF project leader Larry Davis has put together another video update on the artificial den box project with some fantastic video captured with some innovative use of a Go-Pro and a selfie-stick:   Larry writes: “Work at the start of this fiscal year focused on identifying any den boxes that were being used by fishers for reproductive purposes. We monitored all den boxes on a monthly basis by inspecting the inside of each box with a Go-Pro camera inserted through the door. In addition, hair-snaggers installed at the entrance of each box are examined and these were collected when any hair was present. Den boxes that were receiving attention by fishers also had motion detection cameras positioned to capture video of any fisher using the structure. DNA samples from the winter of 2016-17 and the 2017 denning period were submitted for analysis in July 2017. Results of the analysis indicate 26 fisher samples were obtained out of the 39 samples submitted. Other species in the samples included red squirrel (8), American marten, (4), and one black bear. Of the fisher samples, we had 9 different individuals leave DNA at the denboxes (7F and 2M)...

BC Fisher Habitat Website

Pacific_Fisher_cc_for_web
The BC Fisher Habitat Working Group has just launched a new website to assist BC forest licensees and their contractors to identify and retain important fisher habitat.  The site allows forest practitioners to download information and tools specific to their location and operational focus. The site includes: - spatial data that lets planning foresters identify habitats and retention targets for harvested areas - pictorial guides to help on-the-ground field crews identify trees and other habitats important to fishers, and - field guides to help operational staff retain fisher habitat in their day-to-day activities. The web site is also designed for use by trappers, First Nations, and other people who are interested in learning more about fisher conservation. Visit the BC Fisher Habitat Website The Habitat Conservation Trust Foundation is proud to be a major funder of this extension project.

HCTF Visits the Cariboo

HCTF Visits the Cariboo
As part of our evaluation program to ensure HCTF funds are benefiting fish and wildlife conservation, HCTF staff regularly visit project leaders to get an in-depth look at their projects – both on paper (financials) and on the ground. In late September HCTF staff biologist Kathryn Martell and financial officer Katelynn Sander travelled to Williams Lake to conduct evaluations on two projects. The first was the Fisher Artificial Reproductive Den Box Study  led by Larry Davis of Davis Environmental Ltd. Fishers are a threatened species in British Columbia and are also the largest obligate tree-cavity user in North America. They typically use cavities in large diameter trees both for resting in winter, and as reproductive dens. Suitable den trees are rare in the landscape and impacts in many areas of the province have further reduced the availability of this habitat feature. Larry’s project seeks to determine if fishers will use artificial (man-made) den boxes for reproductive dens, as a way to augment denning habitat in areas where natural den trees have been reduced. This year of the study continued the monitoring efforts on the 56 den boxes installed during this project. Larry has been successful in attracting fishers to 50%...

Meet the 2015 Fisher Den Box Kits

Meet the 2015 Fisher Den Box Kits
We received the following video update on the Fisher Artificial Den Box Study from biologist Larry Davis. Davis and his team are trying to determine if female fishers will use human-constructed den boxes to raise their young, as there are very few of the fisher's natural denning sites left in some areas of their range. "Fisher require large diameter trees with heart-rot cavities for reproduction," says Davis. "These trees are rare in managed landscapes."   2015 was the third year of this HCTF-funded project, and Larry and his team continued monitoring the 56 installed den boxes to see if they were being used by fishers. “We have been successful in attracting fishers to 50% of the den boxes, with many of the structures used for resting during winter," reveals Davis. "We identified 45 fisher samples using hair snaggers located at the entrance to the den boxes. Of these, 14 were identified as being unique females, with 8 of them using the structures more than once, and 4 of them detected at 2 different den boxes.” During the 2015 reproductive season, two fisher females used artificial den boxes to give birth to and raise their young. The video features footage of...

Fisher Den Box Study: Video Update

Fisher Den Box Study: Video Update
Last November, we posted about Larry Davis’s fisher inventory project in the Bridge River watershed. Larry is currently working on a follow-up project to determine if artificial den boxes would be used by female fishers to mitigate the loss of their natural denning habitat. Larry has just sent us the following video: it starts out by providing some background on the project, and then shares some of the amazing remote camera footage of fishers (and other curious creatures) checking out the artificial dens.      This project has just been approved for a third year of HCTF funding. For more information on the study, you can contact  Larry Davis  of Davis Environmental Ltd.
