The federal government has decided to continue endangered species protection for two species of plants located on the Hanford Nuclear Reservation.
The U.S. Fish and Wildlife Service on Thursday decided to affirm its April decision to list the two plants as threatened.
The plants are the Umtanum desert buckwheat and the White Bluffs bladderpod. The agency also affirmed the designation of critical habitat for the Umtanum desert buckwheat, but only on federally owned lands.
Portions of the sprawling Hanford site were used to make plutonium for nuclear weapons, but much of the site remains in a natural state.
