- Summary
- range of literature was reviewed and summary information compiled to support the development of a conservation prioritisation strategy for two migratory fish species (īnanga and shortjaw kōkopu) on the South Island’s West Coast. This strategy will support the development of migratory species recovery plans under the government-funded Bio18 programme being implemented by the Department of Conservation. Existing datasets were evaluated and a desktop assessment completed to provide an initial characterisation of conservation value and threat intensity at regional scale. Recommendations are provided for a progressive conservation prioritisation strategy using the best available data. Results of the desktop assessment are presented in this summary report and include a set of spatial data and maps prepared for the use of operational staff who will lead implementation of this project in the coming years. Findings of the desktop analyses included the characterisation of existing information on conservation value and the distribution of threats to the security of these species. Spatial disparities between species distribution models (SDMs) produced on different versions of the River Environment Classification were identified and are described. Model discrepancies may indicate the influences of differences in environmental predictor variables, areas of heightened uncertainty due to environmental conditions, or both.
