BBWM was established to identify atmospheric deposition impacts on surface waters and to quantify the major processes controlling surface water acidification under increased sulfur (S) and nitrogen (N) atmospheric deposition.Baseline Data for Long-term Forest Vegetation Monitoring at Bear Brook Watershed in MaineFernandezDr. IvanEckhoffJ.D.WiersmaG.B.regenerationacid rainnitrogenwatershedsvegetationforest inventoryNumber of Live Saplings1997-07-011997-08-31Forest mensuration indicator: number of live saplings per plot (sum of all four subplots within each cluster-plot), by species, at Bear Brook Watershed, Maine, in 1997.Z1352_2761_WGK27WVMC.1352.2761mySQLEckhoff and Wiersma (2002) Number of Live Saplings.
