Estimate Spatial Population Indices from Ecological Abundance Data

Compute relative or absolute population trends across space and time using predictions from models fitted to ecological population abundance data, as described in Knape (2025) . The package supports models fitted by 'mgcv' or 'brms', and draws from posterior predictive distributions.

spotr

An R-package for estimating population indices from models fitted to monitoring data. The package works with models fitted by mgcv or brms and computes aggregated indices of relative population change across space and time.
