The U.S. Fish and Wildlife Service is proposing protecting 13 Big Island plants, a picture-wing fly and a shrimp as endangered species.

The agency said Wednesday invasive plants, agriculture, urban development and feral animals like pigs, sheep and goats are threatening the plants and animals by destroying their habitat.

It’s accepting comments on the proposal through Dec. 17.

More than 400 species around Hawaii are already listed as endangered or threatened.

The agency says its proposal is part of a court-approved work plan to resolve a series of lawsuits over the agency’s listing of species.

The agency says the agreement aims to reduce work driven by lawsuits.
