With funding from the Northern States Research Cooperative, we established 18 plots in Vermont's managed forests. Most are located in federal, state and town forests, parks and management areas. The initial primary focus was on soil carbon, which serves as a major reservoir for carbon storage in forests. Initial soil sampling was done in 2008/2009, along with measurement of aboveground biomass. In 2012/2013 we resampled to determine earthworm numbers and species, and also performed a detailed land-use history of each site. In addition, four sites were resampled to assess the impact of partial harvesting on carbon in the forest floor. We hope that these plots will continue to provide a good baseline for future work.Long-term Managed Forest Soil Monitoring for Carbon and NutrientsJuilleratJulietteWilmotSandraBurtNancyCogbillCharlieVillarsThomasRossDonaldBrynnDavidAlvesCarolineKnowlesMeghan BriggsJeff ThortonLisa GörresJoseftimber harvestlong term monitoringsoil carbonforest managementvermontearthwormsVegetation-live tree basal area 2008-20092008-05-01Basal area (square meters per hectare) of all live trees greater than 5 cm diameter at a height of 137 cm (also known as 'diameter at breast height'). The plots were modeled on the USDA Forest Service Forest Inventory and Analysis Program. Vegetation subplots were 7.32 m in diameter; one was located at the center of the plot and three were located 36.6 m from the center of the plot, every 120 degrees (at an azimuth of 0, 120 and 240 degrees from the center).
