Think like a conservationist
A conservation lens
Wetland drainage, water withdrawal, invasive species, and pollution can remove habitat faster than fish can relocate.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
