Current and future hydrology and occupancy predictions for boreal toads (Anaxyrus boreas boreas) in the Southern Rocky Mountains

May 23, 2025

These data consist of three primary types of products for managers of boreal toads in the Southern Rocky Mountains: 1) Re-constructed hydroperiods for historical breeding sites from LANDSAT imagery from 1985-2022 (SMA_hydroperiod_reconstruction.csv). This dataset was developed using a Spectral Mixture Analysis (SMA). 2) Current (1985-2022) and future (2040-2069) predictions of probability of drying and surface area estimates for historical breeding sites (Current_hydrology_predictions.csv, Future_hydrology_predictions.csv). These datasets were developed using a Bayesian hurdle model with the surface water area estimate from the SMA as the response variable. 3) Current (1985-2020) and future (1955-1969) predictions of occupancy for boreal toads (Anaxyrus boreas boreas) and the amphibian chytrid fungus (Batrachochytrium dendrobatidis) at three spatial scales; breeding site (Current_future_occ_prob_ind_site.csv), mountain range (Current_future_occ_prob_mtn_range.csv) and Southern Rocky Mountain Region (Current_future_occ_prob_SRM.csv). These datasets were developed from a Bayesian dynamic state-space community model.
