Requirements include

Threats include:

loss of habitat through drainage, infilling or land clearing.
toxic chemicals, which are readily absorbed through amphibian skin and may affect food availability.
loss of native riparian vegetation.
changes in hydrology (water levels and flows) that dry out habitats or wash away egg masses.
introduced predators including dogs, cats, bullfrogs and non-native fishes.

Ensure the use of oil/grease separators, sediment traps, and/or treatment wetlands to treat runoff from paved areas before it enters habitats.
Prevent dumping of toxic materials into storm or sanitary sewers through public education and a by-law.
Ban insecticide and herbicide use for cosmetic purposes on private lands within jurisdiction (municipalities only).
Keep high-risk industries away from sensitive habitats using zoning controls on land use and/or large setbacks from sensitive habitats.

Restore native riparian vegetation and large woody debris on local government lands.
Restrict tree cutting and land clearing in riparian areas using a by-law or development permit area restrictions.
Establish adequate setbacks from habitats through a zoning by-law, development permit areas, and/or the land subdivision process.
Require conservation covenants on riparian areas during the rezoning, subdivision, and development permitting processes

Limit impermeable area in new developments through a zoning by-law.
Use density bonuses to encourage higher density, clustered development and reduce the development footprint.
Require on-site infiltration of rainwater in new developments.
Reduce water use through pricing and lawn watering restrictions.
Reduce reliance on ecologically sensitive sources of municipal water.
Restrict tree cutting on steep slopes.

Enact animal control by-laws to prevent domestic pets from entering species at risk habitats.
Educate the public on the threat posed to species at risk by non-native species.

Restore aquatic and riparian habitats on local government lands.
Create or restore aquatic habitats during drainage maintenance works.
Provide safe aquatic and terrestrial passage routes under roadways.
Install signage or temporarily close roads at known crossing points during critical dispersal periods.
