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.Average Number of Tree Seeds 1997–99Tree seed production indicator: average number of tree seeds collected, by species, for two years (1997–99) and normalized tree seed data from the plots at Bear Brook Watershed in Maine.VMC.1352.2766mySQL/femc/data/archive/project/bear-brook-watershed-maine/dataset/average-number-tree-seeds-1997991997-07-011999-08-31A&Y_(97-98)A&Y_(97-98)No description for this attributedecimalno dataEast_Bear_(97-98)East_Bear_(97-98)No description for this attributedecimalno dataMeasurementMeasurementNo description for this attributetextSpeciesSpeciesNo description for this attributetextAcer 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)West_Bear*_(97-98)West_Bear*_(97-98)No description for this attributedecimalno data
