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.Number of Tree Seeds 1998Tree seed production indicator: number of tree seeds per plot (sum of all four subplots within each cluster-plot), by species, at Bear Brook Watershed, Maine, in 1998.VMC.1352.2764mySQL/femc/data/archive/project/bear-brook-watershed-maine/dataset/number-tree-seeds-19981998-07-011998-08-31A&Y-TotalA&Y-TotalNo description for this attributeintno dataA-1A-1No description for this attributeintno dataA-2A-2No description for this attributeintno dataA-3A-3No description for this attributeintno dataA-4A-4No description for this attributeintno dataA-5A-5No description for this attributeintno dataE-1E-1No description for this attributeintno dataE-10E-10No description for this attributeintno dataE-2E-2No description for this attributeintno dataE-3E-3No description for this attributeintno dataE-4E-4No description for this attributeintno dataE-5E-5No description for this attributeintno dataE-6E-6No description for this attributeintno dataE-7E-7No description for this attributeintno dataE-8E-8No description for this attributeintno dataE-9E-9No description for this attributeintno dataE-TotalE-TotalNo description for this attributeintno dataFHM_CodeFHM_CodeNo description for this attributeintno dataSpeciesSpeciesNo description for this attributeintAcer pensylvanicumITIS #28754, striped maple (Acer pensylvanicum)Acer rubrumITIS #28728, red maple (Acer rubrum)Acer saccharumITIS #28731, sugar maple (Acer saccharum)Betula alleghaniensisITIS #19481, yellow birch (Betula alleghaniensis)Fagus grandifoliaITIS #19462, American beech (Fagus grandifolia)Picea rubensITIS #18034, red spruce (Picea rubens)UnknownITIS #823, (Radiocystis )Acer pensylvanicumITIS #28754, striped maple (Acer pensylvanicum)Acer rubrumITIS #28728, red maple (Acer rubrum)Acer saccharumITIS #28731, sugar maple (Acer saccharum)Betula alleghaniensisITIS #19481, yellow birch (Betula alleghaniensis)Fagus grandifoliaITIS #19462, American beech (Fagus grandifolia)Picea rubensITIS #18034, red spruce (Picea rubens)W-1W-1No description for this attributeintno dataW-10W-10No description for this attributeintno dataW-2W-2No description for this attributeintno dataW-3W-3No description for this attributeintno dataW-4W-4No description for this attributeintno dataW-5W-5No description for this attributeintno dataW-6W-6No description for this attributeintno dataW-7W-7No description for this attributeintno dataW-8W-8No description for this attributeintno dataW-9W-9No description for this attributeintno dataW-TotalW-TotalNo description for this attributeintno dataY-1Y-1No description for this attributeintno dataY-2Y-2No description for this attributeintno dataY-3Y-3No description for this attributeintno dataY-4Y-4No description for this attributeintno dataY-5Y-5No description for this attributeintno data
