U.S. Secretary of the Interior Sally Jewell and others are updating efforts to protect the New England cottontail.
The small brown rabbit has been threatened by a loss of habitat throughout its range in Maine, New Hampshire, Massachusetts, Connecticut, Rhode Island and New York.
It's endangered in Maine and New Hampshire and the U.S. Fish and Wildlife Service has been studying whether to list it under the federal Endangered Species Act.
The cottontail does best in tangled, low-growing shrubs in younger forests. When forests mature and large trees take their place, the rabbit's habitat is destroyed. Habitats also have been lost to land development.
Friday's announcement at the Ambrose Farm in Dover is related to a coordinated effort by federal, state, nonprofit and private entities to protect the cottontail.
