Mission blue butterfly habitat conservation
![](https://commons.wikimedia.org/wiki/Special:FilePath/Mission_blue_artist_rendering.jpg?width=300)
The U.S. Fish and Wildlife Service (USFWS) has a number of programs aimed at Mission blue butterfly habitat conservation, which include lands traditionally inhabited by the mission blue butterfly, an endangered species. A recovery plan, drawn up by the U.S. Fish and Wildlife Service in 1984, outlined the need to protect mission blue habitat and to repair habitat damaged by urbanization, off highway vehicle traffic, and invasion by exotic, non-native plants. An example of the type of work being done by governmental and citizen agencies can be found at the Marin Headlands in the Golden Gate National Recreation Area. In addition, regular wildfires have opened new habitat conservation opportunities as well as damaging existing ones.
