KEEPING CARBON STORED: FORESTS UPDATE

Ecologists Underestimating The Impacts Of Rainforest Logging says a new study, reports Rhett Butler at Mongabay. They fail to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues the published paper, based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests.
The number of birds in forests generally increases with logging intensity as gaps open up habitats for species that thrive in disturbed habitats and grasslands. But mammals, amphibians, butterflies, dung beetles, and ants decline as more trees are removed from a forest.
“We found that mammals and amphibians are the most sensitive groups to selective logging in terms of the rate of decline in species richness,” the authors write. Removing as few as 3-4 trees from about 2.5 acres can halve the species of mammals; removing 6-8 trees halves the species of amphibians.

Stunning High-Resolution Map Reveals Secrets Of Peru’s Forests reportsRhett Butler at Mongabay. Peru’s landmass has just been mapped like never before, revealing important insights about the country’s forests that illustrate the value healthy and productive ecosystems afford humanity.
The study found that vegetation in Peru stores nearly 7 billion metric tons of aboveground biomass, roughly equaling nearly twice the combined annual carbon emissions of the U.S. and China; it also documented ecosystem gradients that underpin the country’s rich biodiversity.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
