APPROPRIATE USE OF THIS DATASET: The NBA 2018 coast Threat Assessment and Protection Level layer has been created for national purposes and the boundaries of some ecosystem types are mapped at a coarse scale. Therefore, the map may act as a guide to the marine ecosystems in a region but is not appropriate for any work requiring fine scale investigations. Much of the map still requires field verification.

In the National Biodiversity Assessment 2018 (Skowno et al. 2019), we sought to address the limitations described in National Biodiversity Assessment 2011 (Driver et al. 2012. Substantial efforts have been made to align the realms at the land-sea interface in order to better represent coastal ecosystem types, and to better assess headline indicators for ecosystem types that have cross-realm linkages and dependencies.
