This dataset includes all research conducted on moose health in New York State from 2021 to 2024. Files include detection histories of moose and other species from camera surveys conducted in the northern Adirondack Park, transect surveys conducted for deer pellet collection and analysis of parasite infection status, and step length measurements of GPS-collared moose. Other files and scripts are associated with 1) the analysis of moose health across the state and parasite infection status in moose, 2) an abundance-mediated interaction model examining direct and indirect interactions between moose, white-tailed deer, and their shared parasites, 3) scripts for the simulation of this moose population under various management and disease level scenarios, and 4) survival analysis of moose calves and adults from the monitoring of radio-collared individuals.
