Endangered species, Jefferson Salamander, return to summer breeding grounds

The City of Richmond Hill is home to one of the few known populations of Jefferson Salamanders in York Region. York Region is working in partnership with Toronto Region Conservation Authority to help ensure their survival.

During this time of year, Jefferson Salamanders, an endangered species, cross Stouffville Road after leaving their winter habitat to travel to their summer breeding grounds.

When Jefferson Salamanders make the crossing, there will be intermittent road closures to ensure safe passage. The closures will only occur during rain events when most salamanders complete their migration.

Travellers can expect intermittent closures of Stouffville Road, between Bayview Avenue and Leslie Street, from Monday, March 24, 2025 to Friday, May 2, 2025, during the hours of 9 p.m. to 5 a.m.

Signs will be posted to guide motorists and local access will be maintained.

This section of Stouffville Road is in the Oak Ridges Moraine Natural Core Area. The Jefferson Salamanders natural habitat requires many of the features found in some areas of the Oak Ridges Moraine and the Niagara Escarpment, including undisturbed natural forests, rocky outcrops, wetlands and ponds. Salamanders are a good indicator of healthy forests and ecosystems in this community.

Recognizing the environmental significance of the area and the species, York Region is constructing a wildlife passage, anticipated to begin in summer 2025.
