Ongoing forest soil monitoring is essential for understanding the impact of human activities. 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.

- dataset_eml_datatabletitle: Soil aggregate data by plot
- dataset_eml_datatablestartdate: 2012-04-29
- dataset_eml_datatableendate: 2024-01-30
- dataset_eml_datatabledescription: Data from 14 of the 18 sites on the fractionation of soil into three aggregate categories and the amount of protected carbon within each category. Also included are earthworm numbers, both total and by ecotype. A separate dataset will have earthworm counts by species. Each site had six subplots that were sampled in three increments: the Oi and Oe horizons, 0-10 cm below the Oe, and 10-20 cm below the Oe. Soil aggregate analysis was done on the mineral soil below the Oe, i.e. the Oa was not included.
