Water note 22 - Herbicide use in wetlands

Guidance
Information about the risk of herbicide use in wetlands.
Last updated:

The majority of the wetlands and river systems of south-west WA have become degraded, suffering from the loss of native vegetation, weed infestation and erosion. Restoration of these systems has become an important focus for many community groups and government agencies.

Weed control is an extremely important part of the rehabilitation process, and is commonly the largest component of a project.

Herbicide is often used to efficiently control wetland weeds, however there is widespread community concern over the effects of these synthetic chemicals on native fauna and flora. The risks of herbicide use need to be balanced against the benefits to the wetland system.
