Recovery of Marine Mammal predators causes unexpected conservation challenges

In the paper, published in the journal Conservation Letters, scientists explored the effects of these recovering predator populations on their home ecosystems, outlining three major unintended conflicts that have resulted. In the Pacific Northwest the comeback of California sea lions and killer whales, as well as Pacific harbor seals (Phoca vitulina), all protected under the MMPA, has increased the animals’ competition with humans for fish. Furthermore, all three predators feed on the ESA-protected Chinook salmon (Oncorhynchus tshawytscha), whose populations are declining. And competition for fish among the predators could adversely affect them all. Read the rest here 10:40
