Habitat Protection and Restoration

Loss of natural habitat is the most significant contributing factor to the reduction of native fish and wildlife species in the Greater Toronto Area.

Habitat ProtectionAs the largest landowner in the Toronto region, the TRCA has the ability to improve or create habitat by modifying the landscape.

A wide range of plant species is essential to create a productive ecosystem. Using a diversity of species heightens the survival rate of planted species and the effectiveness of the project. Different species are planted in patches and clumps across the landscape in order to maximize the amount of cover available to wildlife. This planting scheme also helps to mimic natural succession and allows plants to colonize an area faster through seed and rhizome dispersal.

TernraftsAlong with plants, other structural elements such as rocks, decaying trees, brush, soils and substrate are essential to many species. These abiotic features are an essential part of all natural environments, providing fauna with winter shelter, cover from predators and spawning areas. Adding a diversity of structures to a project site involves reintroducing many natural structural habitat features such as brush piles, logs and rock piles as well as artificial structural habitat such as birdhouses and nesting platforms.

The TRCA has many new exciting initiatives that will help increase the amount of fish and wildlife habitat available within the Toronto Areas of Concern (AOC). These projects include the Toronto Waterfront Naturalization Initiative, wetland creation, Habitat for Wildlife and several new weir mitigation projects.
