These data are summaries and comparisons of the EverForecast outputs from May 2021. EverForecast is a near-term hydrologic forecasting application that provides daily water depth forecasts across the freshwater Everglades (Pearlstine et al. 2020); water depth forecasts are then used to run species models. Here, we examine the EverForecast outputs of five species models: (1) American alligator production probability (i.e., habitat suitability index (HSI)), (2) Florida apple snail (native) population model (EverSnail), (3) Cape Sable Seaside Sparrow probability of presence model (EverSparrow), (4) small fish density model, and (5) wading bird probability of presence model (EverWaders). These species model outputs are summarized on a biweekly (14 day) time step for each EverForecast region into three hydrologic categories relative to the full forecast: (1) low depth, (2) medium depth, (3) high depth. The outputs show tradeoffs among species when selecting hydrologic conditions to prioritize the ecological conditions for one species over others.
