Abstract
 Geostatistical models were used to estimate cockle abundance for 12 sites in the 2019–20 northern bivalve survey. Estimates often had greater precision than the sampling-based estimator, and fine-scale predictions reproduced sampling observations. Nevertheless, results were sensitive to model settings and site configuration. Spatio-temporal models accounting for earlier surveys also improved precision in population estimates, except for sites where cockle beds shifted between years.
