Endangered Species Law & Policy

Recently, the California Assembly passed Assembly Bill 1889, the “Room to Roam Act.” If enacted without changes, the Room to Roam Act would amend Section 65302 of the Government Code to add certain “fish, wildlife, and habitat connectivity” considerations to the provisions governing general plans for land use in Californian cities and counties.

The bill’s passage in the Assembly is a significant development in efforts to reform California’s land use and wildlife conservation policies, as the bill would require local land use decisions to factor in wildlife movement ...

For the magnificent ramshorn (Planorbella magnifica), a fresh-water snail species native to southeastern North Carolina, efforts to secure protection under the federal Endangered Species Act have progressed at a snail’s pace. Today, twelve years after environmentalists originally petitioned the U.S. Fish and Wildlife Service (Service) to list the species, the Service proposed to list the magnificent ramshorn as endangered, and to designate two ponds spanning 739 acres as critical habitat for the species. The proposed rule was prompted by a lawsuit filed by the Center of ...

On June 16, 2022, a vote by the California Fish and Game Commission (Commission) on whether the Western Joshua tree (Yucca brevifolia) should be listed as threatened under the California Endangered Species Act (CESA) resulted in a 2-2 tie. Pursuant to the Commission’s rules, the Western Joshua tree will remain a “candidate” under CESA and the issue will be taken up again at a subsequent Commission meeting. The Commission will take up the Western Joshua tree’s listing status at the agency’s October 12-13, 2022 meeting and will re-open the comment period on the species’ ...

Recently, I authored a post for DeltaCurrents, the Center for California Water Resources Policy and Management's blog. The focus of the piece is on science and humility. It is a topic of broad importance in society though I focus on it in the resource management context, and, specifically, as it pertains to California's Bay-Delta.

For the past three decades, the federal and California governments and diverse stakeholders have looked to scientists to explain the causes of the long-term population declines in fish species native to California’s Bay-Delta in an effort to chart a ...

I recently recorded a podcast as part of the Environmental Law Institute’s (ELI) People Places Planet Podcast series “Engage the Experts.” In our recent discussion entitled “Wind Power & Wildlife,“ I speak with Joy Page, Director of the Renewable Energy and Wildlife team at the Defenders of Wildlife about what it means to work on “wind and wildlife” issues and how that differs given our respective roles. We hope you find the conversation interesting and insightful.

On November 12, 2014, the U.S. Fish & Wildlife Service (Service) listed as threatened and designated over 1.4 million acres of critical habitat for Gunnison sage-grouse (Centrocercus minimus), the smaller cousin of the greater sage-grouse (Centrocercus urophasianus).  The Gunnison sage-grouse’s (Gunnison) current range is limited to southwestern Colorado and southeastern Utah.

The regulations came as a blow to the State of Colorado, landowners, and others who have devoted considerable resources to the conservation of the Gunnison Basin population’s sagebrush ...
