Adverse effects: when stream restoration improves habitat for invasive fish
in Research Briefs | Feb 2, 2010
Research Briefs | Feb 2, 2010 Stream restoration is a commonly used tool for improving the habitat of threatened native fish, particularly salmonids, which have suffered recent declines due to human disturbances. However, as a new study shows, restoration efforts can create their own problems for native fish by unintentionally improving the habitat of invasive species...
