Cutting Trees for the Early Birds

“U.S. Forest Service scientists recently published the results of one of the longest studies conducted on the effects of multiple forest harvest methods on early successional bird species. Published online in Forest Ecology and Management, the articleby Forest Service Southern Research Station research wildlife biologist Roger Perry and retired scientist Ron Thill presents findings from an 18-year study in pine-dominated stands on federal lands in Arkansas and Oklahoma.”

The New Normal

“No one is sure how much of Earth is covered by novel ecosystems, but Erle Ellis, a map specialist at the University of Maryland, has taken a stab at quantifying it. Defining novel ecosystems as “lands without agricultural or urban use embedded within agricultural and urban regions,” Ellis estimates that at least 35 percent of the globe is covered with them. Their share of the planet will probably expand, and many ecologists think that these novel ecosystems are worthy of study and, in some cases, protection.”
