The Department of Homeland Security has sued The Nature Conservancy to condemn land in a South Texas nature preserve for the border fence.
The conservancy's Lennox Foundation Southmost Preserve, which includes more than 1,000 acres along the Rio Grande near Brownsville, is home to a rare grove of native sabal palms, a South Texas native plant nursery for reforestation projects and habitat for the endangered ocelot and jaguarundi.
The government offered the conservancy $114,000 for a strip of land that would leave three-quarters of the preserve, including the property manager's home, in the no-man's land between the fence and Mexico, according to court records filed earlier this month.
The Nature Conservancy's preference is no fence and no compensation, but the offer failed to take into account the impact to the rest of preserve, Laura Huffman, The Nature Conservancy's state director, said Monday.

Colorado River may face fight of its life
Now the life vein of the Southwest faces another threat: Energy companies are sucking up the Colorado's water to support increased development of oil, natural gas and uranium deposits along the river's basin. The mining and drilling will likely send more toxins into the waterway, which provides drinking water for one out of 12 Americans and nourishes 15 percent of the nation's crops along its journey from Wyoming and Colorado to Mexico.
Coal Ash Spill Is Much Larger Than Initially Estimated
A coal ash spill that blanketed residential neighborhoods and contaminated nearby rivers in Roane County, Tenn., earlier this week is more than three times larger than initially estimated, the Tennessee Valley Authority said on Thursday.
Coal ash, a byproduct of burning coal, contains toxic heavy metals like arsenic, lead and selenium that can cause cancer and neurological problems.
Massive coal-ash spill causes river of sludge and controversy
What may be the nation's largest spill of coal ash lay thick and largely untouched over hundreds of acres of land and waterways Wednesday after a dam broke this week, as officials and environmentalists argued over its potential toxicity.
Federal studies long have shown coal ash to contain significant quantities of heavy metals such as arsenic, lead and selenium, which can cause cancer and neurological problems. But with no official word on the dangers of the sludge in Tennessee, displaced residents spent Christmas Eve worried about their health and their property and wondering what to do.
The spill reignited a debate over whether the federal government should regulate coal ash as a hazardous material. Similar ponds and mounds of ash exist at hundreds of coal plants nationwide.
Faster Climate Change in US Feared
The United States faces the possibility of much more rapid climate change by the end of the century than previous studies have suggested, according to a new report led by the U.S. Geological Survey.
Coalition sues over mining ruling
A coalition of environmental groups including Kentucky Waterways Alliance has sued the Interior Department and U.S. Environmental Protection Agency, seeking to overturn a new rule that will make it easier for mining companies to dump waste rock into streams.
The revisions, made final Dec. 12, will let mining companies disregard a 100-foot stream buffer zone if they are able to convince regulators that no other option was available and that they had taken steps to minimize harm to the environment.
"The notion that coal mining companies can dump their wastes in streams without degrading them is a fantasy that the Bush administration is now trying to write into law," said Judith Petersen, executive director of Kentucky Waterways Alliance.
More than 100 million Americans breathe sooty air
More than 100 million people living in 46 metro areas are breathing air that has gotten too full of soot on some days, and now those cities have to clean up their air, the Environmental Protection Agency said Monday.
The EPA added 15 cities to the sooty air list, mostly in states not usually thought of as pollution-prone, such as Alaska, Utah, Idaho and Wisconsin. That's probably because of the prevalence of wood stoves in western and northern regions, a top EPA official said. But environmentalists said the EPA was only doing half its job on soot-laden areas, letting some southern cities with long-term soot problems _ such as Houston _ off the hook.
