Abstract
A spatial risk assessment of threats was undertaken for Hector’s dolphins (Cephalorhynchus hectori) and their closely-related sub-species MÄÂui dolphin (Cephalorhynchus hectori maui), to inform a revised Threat Management Plan (TMP) for the species. A Bayesian spatial risk model was developed using the spatially-explicit fisheries risk assessment (SEFRA) approach. Under this approach, encounters between animals and lethal threats such as fishing are estimated as a function of their overlap in space, and the probability of death per encounter is estimated from fisheries observer data or other observations of deaths.
