One of the things about working with nature is that you never can predict what is going to happen. Science is a tool we use to help guide our decisions, but when it comes down to it nature is going to do its own thing.
Our latest experience with this has been the 2017 Toadlet migration. Before we installed the toad tunnel, we spent many years researching the best location where it could help the most toads cross the road safely. For the first two years it worked well, they migrated along the directional fencing we installed with the help of volunteers, to either the tunnel or the culvert under Elk View Road. This year we were super prepared for the pending migration, everything was meticulously installed while the weather warmed up and the toad tadpoles morphed into little tiny toadlets. However, instead of following their usual route out of the wetland, across the hay field, they decided to go in the opposite direction this year! So now there are streams of migrating toadlets, crossing Elk View Road out of the other end of the wetland and too far south from our fencing and tunnel to benefit from its safe passage. Only the occasional toadlets are migrating the other direction and can benefit from the use of the tunnel.
Therefore, it is especially important this year that people follow the voluntary detour. The toadlets are so tiny it is impossible to see them when driving, many people don’t even notice them when walking. There is no way to avoid killing toadlets driving on Elk View Road between Ryder Lake and Huston Roads, however there is a simple detour that only adds 300m to the drive. The only way can help the toadlets this year is by taking the detour.
We will endeavour to continue to post updates on our YouTube channel if you want to follow there migration progress this year.
Hopefully next year they will continue with their usual migration route. In the meantime, the FVC staff will review the results from this year’s data collected and see if we can come up with an alternate safe crossing if the toadlets repeat this pattern again in the future.
