Regional or Local Number: PP-2010-5539

Notice is hereby given that pursuant to the provisions of section 74 of the Species at Risk Act permit no. PP-2010-5539 is issued.

Purpose:
Scientific research for the conservation of the species

Description:
Systematic surveys were initiated in 2001 for the presence of Lake Erie Water Snake and Eastern Foxsnake on Middle Island, part of Point Pelee National Park. This involves searching for, capturing and measuring snakes; determining identity of previously implanted passive integrated transponders (PIT tags) for identification or implanting a PIT tag in new snakes; and releasing the snake. This ongoing study provides information on population demography and size.

Start Date: 2010-06-02   End Date: 2012-09-30

Issuing Authority: Parks Canada Agency

Authority Used:

  • Species at Risk Act
  • Canada National Parks Act

Location of Activity (province, territory or ocean):

  • Ontario

Affected Species:

Pre-Conditions:
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; No reasonable other alternative have been found. Generating population estimates for snakes can only be done accurately using mark-recapture, particularly in a habitat as complex as Middle Island with its rocky shores. Snakes must be individually marked so that accurate counts and estimates can be made. PIT tag implantation is done subcutaneously and is generally accepted in the snake research community as a very low impact, highly reliable method of permanently marking and identifying snakes. Length/weight measurements using scales and measuring tapes is non-invasive and is the only practical field method to obtain this information. 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; and PIT tags will only be implanted into healthy, adult snakes (not neonates). Implantation will only be done by experienced individuals and will follow current and professionally accepted methodologies as outlined in an Animal Utilization Protocol (OMNR 2001) and the guidelines outlined in Ontario’s Snake and Lizard Advisory Group’s Invasive Procedures Protocols for snakes. All snakes will be released to their capture location as quickly as possible. Sexing will be done by visual inspection whenever possible. Occasionally, visual appearance leads to ambiguous determination of sex, requiring the snake to be inspected with a blunt probe to determine sex. The need for this will be determined by the lead researcher and will only be conducted with sterile equipment and by experienced personnel. c) the activity will not jeopardize the survival or recovery of the species. Effects of PIT tagging are expected to be minimal given the short time the animal is held and the simplicity of the procedure. This low impact method of identification has been used extensively on many species of snake in Canada and the number of healthy animals recaptured suggests little effect of the marking procedure on animal survival or health. Surveying is a prescribed activity in the draft Recovery strategy for these species and will aid in recovery and conservation efforts.
