We’re just ten minutes into a walk next to the Ruisseau de la Brasserie when a hip-wader-clad Daniel Toussaint emerges from the bushes, proudly holding his hand out. Toussaint, a biologist with Ressources naturelles du Quebec, is carrying a crayfish about eight centimetres long, found under a rock in the stream. Once identified, it would be recorded as one of dozens, or even hundreds (numbers are still being tallied), of species counted that day in and around just one tiny offshoot of the Ottawa River.
Last week, Toussaint and other experts guided volunteers and the curious public on walks along the stream in what is known as a “bioblitz,” a 24-hour quest to document as much of the life as possible in a given area. A bioblitz helps give scientists an idea of what lives where, but it also gives the public a chance to see just how much life exists within walking distance of home.
The Ottawa Riverkeeper organized the bioblitz at the Ruisseau de la Brasserie, but organizations across the country hold similar events. Regular bioblitzes happen in Vancouver and Whistler, and the Canadian Wildlife Service is in the process of developing a protocol to make it easier for groups to organize their own local bioblitzes.

This past summer an ambitious wildlife under/overpass system broke ground in B.C. on a deadly stretch of highway just west of the Alberta border. Here’s how it happened.
