Figure 3: Abundance between 1993 and 2012 for eight EAAF migratory shorebird taxa found in four non-breeding population nodes.

Abundance estimates are posterior means for each node from Bayesian N-mixture models of counts across Australia and New Zealand, including the majority of internationally important sites. Lines show posterior mean abundance estimates for each year, with red lines indicating credibly declining populations and grey shading denoting the 95% CRI. Map insets indicate the location of the four population nodes: (1) northwestern Australia; (2) Queensland; (3) southeastern Australia and (4) New Zealand. Lesser sand plover and the menzbieri subspecies of bar-tailed godwit were not included in analyses because they occurred on only one node.
