Our 2014 telemetry pilot study year
was a success!
Last fall we successfully tracked 8 adult
toads and found 6 hibernacula (hibernating locations). We
monitored the hibernating sites through the winter and in the spring we were
lucky to have one of our toads lead us to a new (previously unknown to us)
breeding site in the Sahtlam area.
First toad fitted with a transmitter on Oct 21, 2014 and released later that same night. |
Transmitter belt |
We fitted each toad with a small belt that has a little radio transmitter and released the animals where we first found them.

Using a hand held radio receiver, we went out on a weekly basis to locate each individual to follow their movement patterns and identify winter hibernation sites.

Toad 1 bedded down in leaf litter in late October. |
At each radio-location a visual of the toad was obtained if the animal was at or near the surface. On occasion the toad was handled to check belt fit and to monitor skin condition. For the majority of the radio-locations, only a photograph was taken to minimize stress for the animal.

Four toads were visually observed after emergence from hibernation starting in early January which coincided with average daily temperatures at or above 6 degrees.
Telemetry 2015
The Western
Toad winter hibernation radio telemetry project is starting up again this
September and will be running until approximately March 2016. We will be looking for adult toads starting
in early to mid-September and would like to have 15 toads on the air. We will then track and monitor these toads on
a regular basis to try and identify where they choose to spend the winter
months.
Public Meeting
We are
planning a project update talk and training
session on Tuesday September 22nd from 7 pm to 8:30 pm at the Sahtlam Fire Hall. We are
also hoping to get some media coverage this fall to help raise the awareness of
this project. One of the biggest
challenges that we face is access to private property as we follow toads
throughout the landscape. We would
greatly appreciate the support and cooperation of land owners regarding access
if a toad moves onto their property, as we do not want to trespass and we respect
peoples’ privacy. If you live in the
Sahtlam area, please talk to your neighbours and encourage them to join us at
the public meeting this September to learn more about our project.
