CDFW working to improve negative effects of non-consumptive recreation on conservation

Editor’s Note: As we publish this article, California, the nation, and the whole world are gripped by the COVID-19 pandemic. To slow its spread and not overwhelm healthcare resources, distancing and stay-at-home orders have led to the delay of trout openers and other fishing events, and closure of parks, reserves and many other publicly accessible facilities. Stories are beginning to emerge of increased wildlife presence in park and reserve areas that are normally filled with people. We look forward to the end of the pandemic and its horrible devastation will be over very soon but we know it will be some time before we realize a return to “normal.” We hope to gain from this emergency more information on wildlife’s response to fewer visitors – data that may be able to help us improve our management of parks and reserves in a way that protects wildlife and their habitat while also providing reasonable recreation experiences. In the meantime, stay well, and stay home to save lives.
