Aquatic & Riparian Restoration

See slideshow of the 14 Lakes habitat enhancement project.

A variety of stream and riparian (streamside) projects are being implemented to restore and enhance fish habitat and to protect and improve water quality. These measures primarily aim to restore natural stream processes that serve to create and maintain conditions to support healthy fish populations.

Riparian forests are also important wildlife habitat, providing valuable forage, cover, and complex habitat structure. Stream restoration projects include large woody debris placement, revegetation of unstable banks, and stream crossing projects to pass peak flows and to ensure adequate fish passage. 

Riparian restoration treatments include conifer underplanting and release in deciduous dominated riparian stands; restoration thinning of dense, young conifer stands; and ecological thinning of mid-successional stands.
