Key Points

A study led by the University of Jyväskylä in Finland evaluated, for the first time, an ecological threshold for the amount of clearcutting in boreal forests. According to the results, maintaining populations of bird species specialized in old-growth forests requires either a forest rotation period of at least 90 years on average or that approximately one-fifth of the forest area be excluded from clearcut management. The study provides a concrete target for the ecologically sustainable use...

Lakes aren't just storing water—they're changing the carbon cycle

Lakes may look like picturesque stopping points along a river or stream, but they can have a big influence on what happens to carbon as it moves through a landscape. New research suggests that the more lake-rich a network of streams is, the more carbon is released into the atmosphere rather than carried downstream.
