Habitat

Monitoring of physical habitat conditions along and within the San Joaquin River provides information on potential needs and limitations for fisheries.

Habitat
Maintaining quality habitat is paramount to a healthy river ecosystem, both in and out of the water. Below is a video illustrating efforts to improve shoreline riparian habitat through invasive species removal. The effort is the result of a partnership between the California Conservation Corps and the San Joaquin River Parkway & Conservation Trust.
