As the last ice age came to an end and the planet warmed, the Earth's vegetation changed dramatically, reports a University of Arizona-led international research team.
The current warming from climate change may drive an equally dramatic change in vegetation within the next 100 to 150 years unless greenhouse-gas emissions are reduced, the team wrote.
"We found that ecosystems all over the globe experienced big changes," said Connor Nolan, a doctoral candidate in the UA Department of Geosciences. "About 70 percent of those sites experienced large changes in the species that were there and what the vegetation looked like."
NSSF reports and others detail economic impact of spending on hunting, target shooting and sportfishing in America.
NEWTOWN, Conn. — New economic reports reveal that more than 53 million Americans consider themselves sportsmen, spending more than $93.5 billion in 2016 on gear, licenses, travel, clothing, gas and more in connection with their hunting, target shooting and sportfishing activities.
Washington, D.C., August 16, 2018 — The U.S. Department of Agriculture (USDA) Forest Service (USFS)announced today a new strategyfor managing catastrophic wildfires and the impacts of invasive species, drought, and insect and disease epidemics.
Charred landscapes, torched buildings and the loss of property and life. These are the consequences of massive wildfires. Most Americans in the Eastern United States aren’t acquainted with this type of destruction. However, these scenes are all too familiar for those of us who live in the West.
Congress and the U.S. Forest Service have the opportunity now to stop catastrophic wildfires before they start. This is not some pie-in-the-sky hyperbole coming from Washington. It’s a realistic goal, achievable by using proven science to manage our country’s forests.
ARCATA, Calif. —The USDA Forest Service has released the Northwest Forest Plan science synthesis, a report that will serve as the scientific foundation for land management planning in northern California, western Oregon and western Washington.
One of the most significant findings of the Northwest Forest Plan science synthesis is that the plan has protected old-growth forests as habitat for important species. At the same time, the report found that restoration of fire and other active forest management activities at the landscape scales can promote ecological integrity and rebuild forest resilience to disturbance and stressors.
