Burn, grow, graze, and repeat. This is a formula that integrates fire and grazing strategies to restore grass to rangelands in the southern plains of the United States. Throughout the world, woody plants are showing an increased presence in grasslands and savannas, reducing the amount of grasses to sustain livestock and altering wildlife habitat and biodiversity. In the U.S. Great Plains, honey mesquite has encroached upon native grasslands to impact cattle grazing strategies and necessitate development of plant control efforts.

This was true regardless of the urban regions’ climate zone, population size, or rate of growth.
Invasive Plant Science and Management – A field test in Montana pitted dog against human in an effort to identify and eradicate spotted knapweed. This weed threatens the survival of native species and can bring about both economic and ecosystem damage. Finding plants in order to eradicate them before they can spread creates a challenge for human eyes, but not for dog noses.

The wipe material, designed for the U.S. Military, proves itself on the soiled beaches of Grand Isle, La.
It is a well-known fact that trees provide many benefits to city dwellers such as shade and clean air. But when it comes to Torontonians who appreciate trees versus others who plant them in their backyards to revitalize the city’s urban forests, it depends on which neighbourhood you live in, say Ryerson University researchers.
Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world’s oceans. But most of those have studied single, isolated sources of pollution and other influences. Now, a marine geochemist at the Woods Hole Oceanographic Institution (WHOI) has published a report in the latest issue of the journal Science that evaluates the total impact of such factors on the ocean and considers what the future might hold.
A research team led by the University of Illinois at Chicago has advised the Illinois Environmental Protection Agency to phase in green infrastructure requirements for better and cheaper control of stormwater in all new development and redevelopment.
Atmospheric research often focuses on clouds’ impact on weather and climate. Yet even low clouds are a long way off, with a base some 6,000 feet above earth.
