NYDensiPOPd Web Interactive Version 2: Software to investigate the population scale impacts of lead in New York State from 1990-2018

Other Titles


We assessed the population scale impacts of lead (Pb) toxicosis in bald eagles (Haliaeetus leucocephalus) in New York State, USA from 1990-2018 under high- and low-density scenarios. The NYDensiPOPd V2 repeats the comparison of Pb and non-Pb in DensiPOPd (, but with a geographic area specific to New York State. The comparisons include the early (low-density; 1990-2006) and later (high-density; 2002-2018) windows of population recovery. The summarized time series data appear in this packet. The raw data may be obtained by contacting the Wildlife Health Unit at the New York State Department of Environmental Conservation [ or (518) 478-2203].
