Notice of permit
Regional or Local Number: SARA-QR-2017-0388
Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. SARA-QR-2017-0388 is issued.
Scientific research for the conservation of the species
This permit authorizes to collect (via cutting) and possess small pieces of butternut branches found in the dead part of the tree’s crown for the purpose of laboratory analysis. Up to five branch samples per tree, with a maximum length of 30cm, is allowed. Approximately 20 butternut trees will be sampled.

Location of Activity (province, territory or ocean):
(a) All reasonable alternatives to the activity that would reduce the impact on the species have been considered and the best solution has been adopted. All alternatives were considered, including doing nothing, performing visual surveys to identify signs of the presence of the canker, or taking samples for laboratory testing. Not doing the project would not allow for the identification of phenotypes resistant to butternut canker and may reduce the chances of recovery of the species. As some individuals who are located near trees affected by the disease, do not show symptoms of canker, visual classification is not a recommended approach. The sampling of branches, in the dead crown of the butternut tree, for laboratory analysis is therefore the most reliable solution to identify the presence of the disease. (b) All feasible measures will be taken to minimize the impact of the activity on the species or its critical habitat or the residences of its individuals. The work will be done by qualified staff of the National Battlefields Commission. The activity will be realized in collaboration with Mr. Pierre DesRochers, forest pathologist at the Canadian Forest Service, recognized for his work on butternut canker. Laboratory work will be carried out by experienced staff on canker identification. The tools will be disinfected with 70% alcohol after each cut. Sampling methods will be non-invasive (hand pruning shears, ladder, nacelle or climber without crampons). The disposal of the samples will not increase the spread of the disease. (c) The activity will not jeopardize the survival or recovery of the species. The proposed activities will have a low impact on approximately 20 butternut individuals. Tree sampling in the dead parts of the tree crown will not jeopardize the survival or recovery of the species. The main threats to this species are the butternut canker, large scale deforestation, and land conversion.
