The Center for Biological Diversity and other environmental groups are threatening to sue the U.S. Fish and Wildlife Service and Interior Department to force action on over 400 proposed listings under the Endangered Species Act. Public Lands Council Executive Director Ethan Lane says these groups are hampering species recovery by putting in arbitrary listing decision deadlines.

He says the environmental groups are pushing their agenda across the country. They started in the West and are now moving to the Midwest.

Lane says his group is in favor of listing endangered species, but it must be done properly based on research and sound science.

Lane says the current Endangered Species Act is broken. Over the nearly 40 years since it was passed, the Act has a recovery rate of less than two-percent with over 2,000 domestic species listed.
