In conjunction with geostatistical techniques, including universal kriging, aerial survey information was used to develop a spatially-explict model of dugong relative density and distribution calculated at a grid size of 2km × 2km. Marine Biology Derived from model dugong relative density distribution Aircraft Models N/A Per request by the data provider, point observations are not included. Please contact the data provider if you wish to obtain them. Due to the lack of point observations, some features on the Dataset Detail are not available.<br/> The model outputs (dugong density and conservation values) are downloadable. Switch to [Download] tab and click "Get this data as ESRI shapefile." They are in fact rasters. Refer to the reference for more detail.

The dugongs range is large, complex and dynamic and extends over multiple jurisdictions. Models of dugong relative density and distribution in Australian waters were developed to inform government agencies and other interested parties on the suitability of various managment regimes, including the design of area closures. notPlanned Alana Grech James Cook University Primary contact alana.grech@jcu.edu.au NA NA NA Alana Grech owner NA zd_481 2025-07-31T14:17:59-04:00 dataset Grech, A. 2008.
