This invasive grass that already has a grip on about 2 million acres in the West makes the rangeland it invades virtually worthless for grazing, harms many animals that contact it or try to eat it, increases wildfire risk, and creates monocultures that have very low biodiversity and crowd out numerous native plant and animal species.
The map and report on known greater sage grouse high-density breeding populations is a starting point that can be refined with the input of state fish and wildlife agencies. But you can use it right away as you cover various land use and environmental issues.Region:
Land owners signed up to protect 272,762 acres, which in one year adds about 12% of the total acreage covered during the 15-year history of the voluntary Wetlands Reserve Program. Funding for the 1,414 contracts totaled $592,562,106.
There were just 12 of these hypoxic areas in the 1960s. Now there are more than 300, or nearly half of the 647 waterways investigated by a consortium of federal agencies that released its report on Sept. 3, 2010.
Summaries of marine diversity in eight settings around the globe have been published, with another 17 scheduled to be added in coming weeks. One of the discoveries was that the Gulf of Mexico is the fifth most diverse marine setting in the world for known species.
Nearly 150 species of North American birds are in significant trouble, according to a report released May 11, 2010, by a consortium of US, Canadian, and Mexican government agencies, NGOs, universities, and individuals.
A new report by the US Geological Survey, Bureau of Reclamation, US Forest Service, other federal agencies, and university experts says the water-hogging reputation of the two species has little merit, but found that effects on wildlife are mixed.Region:
The exact ingredients of the chemical mixture being sprayed on and pumped into the spreading BP oil spill are secret, even though some are rated toxic and may endanger the health of Gulf residents and ecosystems.SEJ Publication Types:Topics on the Beat:Region:
Bat losses can have major impacts on ecosystems, as they routinely consume large quantities of insects and themselves provide food and nutrients for other plants and animals. There also are economic impacts as caves close to recreational use, in an effort to combat the spread of the disease.Region:
