Analysis of 60‐year records of daily streamflow in the Andrews Forest revealed that the conversion of old‐growth forest to Douglas‐fir plantations had a major effect on summer streamflow.
A new study indicates average breakdown rates of leaf litter in streams and rivers may increase 5-21% with a 1 to 4 degree Celsius rise in water temperature — half as much as the 10-45% increase predicted by metabolic theory. Mean annual water temperature for some streams and rivers is currently rising at an annual rate of about 0.01 to 0.1 degrees Celsius due to changes in climate and land use.
New research from the Andrews Forest suggests that old-growth forests may provide a buffer against rising air temperature. Press release: http://bit.ly/1U7sBkd
Researcher Alba Argerich and colleagues suggest that forested watersheds may not store quite as much carbon as previously thought. Small, headwater streams, such as those found in the Andrews Forest, import a higher than expected amount of carbon. The paper, "Comprehensive multi-year carbon budget of a temperate headwater stream," was published in Biogeosciences.
The amount of carbon stored in tree trunks, branches, leaves and other biomass — what scientists call “aboveground live carbon” — is determined more by timber harvesting than by any other environmental factor in the forests of the Pacific Northwest, according to a report published by researchers at Oregon State University.
