Double-crested Cormorant (Nannopterum auritum) nesting colony and environmental data in Biscayne National Park, Florida, USA (2009-2024)

Double-crested Cormorant (DCCO) nesting data were collected from colonies in Biscayne National Park (BISC) by the South Florida/Caribbean Inventory and Monitoring Network as part of the Colonial Nesting Birds vital sign monitoring program. Nesting data collected from 2010 to 2023 are included in this dataset. Salinity, chlorophyll, and ammonia data were acquired from sites monitored in the Surface Water Quality Monitoring Program managed by the Miami-Dade County Division of Environmental Management’s Department of Regulatory and Economic Resources (RER-DERM). Seagrass data were acquired from sites monitored by RER-DERM as a part of the Biscayne Bay Benthic Habitat Monitoring Program. Mangrove fish and epifauna data were acquired from the U.S. National Oceanic and Atmospheric Administration's (NOAA) Integrated Biscayne Bay Ecological Assessment and Monitoring Project (IBBEAM). Environmental data (salinity, chlorophyll, ammonia, seagrass, mangrove fish, and epifauna) were manipulated in order to examine the relationship between DCCO nesting trends and the BISC ecosystem. This data package is completed. Code included is pertinent to the methods described in "Assessment of ecosystem health in Biscayne National Park, Florida according to Double-crested Cormorant (Nannopterum auritum) nesting trends" by Taylor et al. 2025, currently submitted to and under review by Ecological Indicators.
