A federal judge has ordered the temporary closure of the Oceano Dunes State Vehicular Recreation Area in California to protect the endangered snowy plover shorebird. The ruling states that the California State Parks has failed to obtain the required incidental take permit under the Endangered Species Act, which would allow a limited number of the birds to be impacted by off-road vehicle use.

Why it matters

The Oceano Dunes is a popular off-road recreation area, but it is also home to the threatened snowy plover. This ruling aims to balance environmental protection with recreational access, as the plover population has grown significantly under State Parks' management, but a small number have still been harmed by vehicles. The decision highlights the ongoing tensions between conservation and off-road use in sensitive coastal habitats.

The details

U.S. District Court Judge Anne Hwang ruled that California State Parks cannot allow off-road vehicles on the Oceano Dunes without an incidental take permit from the U.S. Fish and Wildlife Service. This permit would outline a habitat conservation plan to mitigate impacts to the snowy plovers. State Parks has failed to obtain this permit over the past 20 years, despite the plover population growing from around 30 breeding adults in 2002 to over 200 in 2024 under their management.

  • The temporary closure of the Oceano Dunes to off-road vehicles will begin on Tuesday.
  • The U.S. Fish and Wildlife Service must approve a habitat conservation plan before State Parks can seek an incidental take permit to reopen the Oceano Dunes.

What’s next

The U.S. Fish and Wildlife Service will need to approve the habitat conservation plan before California State Parks can seek an incidental take permit, which will allow them to reopen the Oceano Dunes State Vehicular Recreation Area.

The takeaway

This ruling highlights the ongoing challenge of balancing environmental protection and recreational access in sensitive coastal areas. While the snowy plover population has grown under State Parks' management, a small number have still been impacted by off-road vehicles, prompting the temporary closure until a comprehensive habitat conservation plan can be approved.
