Integrated Population Model & Population Viability Analysis of the Cape Sable Seaside Sparrow (CSSS, Ammospiza maritima mirabilis)

This software release contains the R code to jointly run an integrated population model (IPM) and Bayesian population viability analysis (BPVA) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis). The CSSS is a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA. The IPM-BPVA synthesizes thirty years (1992-2021) of range-wide surveys, mark-resight, and nest monitoring data to estimate annual abundance, apparent survival, fecundity, and growth for six separately managed CSSS ‘subpopulations’ (A-F) and simultaneously project population size and demographic rates into the future under user-defined scenarios. A suite of hydrologic and fire metrics within occupied and potentially occupied areas for each subpopulation are calculated to evaluate the effects of hydroperiod on juvenile and adult survival, and the effects of water depth variability, amount of dry area, time since fire, and percent area burned on fecundity. This software release also contains the R code to calculate the hydrologic and fire metrics used in the IPM-BPVA.
