Dugongs (Dugong dugon) are listed as vulnerable on the IUCN Red List of Threatened species and as other specially protected fauna in WA under Schedule 7 of the Wildlife Conservation (Specially Protect... moreed Fauna) Notice 2015). Gaps in our knowledge in Western Australia include having a good understanding of the species’ distribution, abundance and high use areas across the northwest.
This 3-year project (2014-2017) integrated Indigenous knowledge and scientific observations from field surveys to better understand the distribution, abundance and movements of dugong in the Kimberley region. The data collected also provides a baseline for future monitoring and management.
This medata record relates to raw and processed aerial survey data of marine fauna collected between 21st September 2015 and 8th October 2015 in Kimberley coastal waters to the 20m bathymetry line, comprising dugongs (Dugong dugon), Australian snubfin dolphins (Orcaella heinsohni), other dolphins (bottlenose, spinners, false killer whales), humpback whales (Megaptera novaeangliae) and large, mostly green turtles (Chelonia mydas).
The WA Department of Biodiversity Conservation and Attractions (DBCA, ex-DPaW) and CSIRO provided additional resources to extend the North Kimberley dugong aerial survey boundary westwards (Broome to just past Port Hedland) to cover the South Kimberley-Pilbara coastal regions, to close the last remaining knowledge gap of the dugong distribution and abundance in Australia. This additional survey was completed in May 2017.
Data from a trial movement study undertaken between 1-18th August 2016 also forms part of this metadata record. Five dugongs were tagged with Telonics manatee/dugong tags. GPS and ARGOS satellite detection locations and dive data were downloaded weekly from the ARGOS web site.less

Herbivory is a key ecological process that sustains food webs, and can regulate the biomass of primary producers in an ecosystem. It has long been hypothesized that rates of herbivory are greatest in ... morethe tropics, although strong evidence to support this is limited. The aim of this project was to identify the key species of herbivores, to identify the grazing rates of key herbivores, and in conjunction with project WAMSI 2 KMRP Project 2.2.4 (benthic primary productivity) provide estimates of the proportion of production that is consumed by herbivores. The research on herbivory was focused on the islands and coast of the Bardi Jawi Indigenous Protected Area in the Kimberley (Western Australia), encompassing Jalan (Tallon Island) and Iwany (Sunday Island). Focus of the herbivory study was on one type of habitat (seagrass meadows), and the diet of two species of herbivores (golden-lined rabbitfish and green turtle). Four surveys were conducted between October 2014 and April 2016. At these locations the following measurements or collections were made (not all measurements were made during each survey): (1) Rates of herbivory (three surveys). These data are presented in the report for WAMSI KMRP 2.2.4, here the focus is on assessing rates of herbivory as a proportion of primary production; (2) Collections of golden-lined rabbitfish (Siganus lineatus); and (3) Blood samples from green turtles (Chelonia mydas). Ten green turtles were tagged with satellite tags: 4 in April 2015, and 6 in April 2016. This data record only pertains to data held by CSIRO. For access to all other data generated by collaborative research partners of the KMRP 1.1.2 project refer to the additional metadata field.less
