Invasive Alien Species in Quebec: Document and Report with Sentinelle

Photograph an observation, record its location without spreading the species and submit a useful Sentinelle report.

Observe without moving it. Do not collect, transport, release or destroy an unknown species to obtain a better photo. Some species are regulated, dangerous or easily spread by a small fragment, seed, mud or water.

Create a useful observation

Take several clear photos: the whole organism, identifying details and surrounding habitat. Record the date, coordinates or precise location, approximate number, habitat and how it was observed. Do not publish someone else's private address.

Check without forcing identification

Compare the observation with official Sentinelle fact sheets. When several species look alike, submit the photos and state your uncertainty. A well-documented observation is more useful than a guessed name.

Limit spread

After an outing, remove mud, plants and organisms from boots, tools, boats, trailers and gear. Drain water only where permitted and follow rules for the waterbody. Never release an aquarium animal, plant or live bait into nature.

Report

Use the free Sentinelle tool to submit the observation. For an immediate danger, significant mortality, infrastructure impact or an issue on municipal land, also contact the authority responsible for the site.
