A nonprofit group has donated more than 3,000 acres of desert land to the Mojave National Preserve.
The Mojave Desert Land Trust announced Wednesday that it had handed over ecologically and historically significant land to the park. The 110 parcels already are surrounded by the national preserve. They include juniper and yucca stands and a century-old homestead site.
The trust has an ongoing program to buy up private land that survived within the boundaries of the Mojave National Preserve, Joshua Tree National Park and Death Valley National Park.
"Development of this private land can degrade neighboring park resources, impact public access and cause management problems for park staff," a trust statement said.
Over the past decade, the trust has conveyed about 23,000 acres of land to the National Park Service.
