► dataset_eml_abstractheader
Long-term monitoring of forest soils is necessary to understand the effects of continued environmental change, including climate change, atmospheric deposition of metals, and recovery from acidic precipitation. A monitoring program was initiated in 2002 at five protected forest sites in Vermont, three in Mt. Mansfield State Forest and two in the Lye Brook Wilderness Area. Every 5 years at each site, ten soil pits are dug and sampled from subplots in a 50 × 50-m plot.
