NESP A12: Northern Australia threatened species

Of the ~80 EPBC-listed Threatened and Migratory marine species known to occur in the North Marine Bioregion, 16 were identified as priority species through consultation with research end-users and experts. The priority group consisted of three sawfishes, two river sharks, Dugong, two inshore dolphins, six shorebirds and two turtles. Dwarf and then Green Sawfish had the most data gaps, indicating that these were the most poorly-known of the selected priority species in the North Marine Bioregion, and as such are a priority for research. These were followed (in order of data gaps) by the other river sharks and sawfishes, inshore dolphins, Hawksbill Turtle, Dugong, Olive Ridley Turtle, and shorebirds. Research assessing the relevance and impact of pressures was identified as a gap for all species. New data identified during the project can fill data gaps for all 16 species, and the analysis of these datasets can improve the accuracy of distribution maps, but new data collection is still required for all sharks and sawfishes, Hawksbill Turtle, and inshore dolphins to improve data coverage for distribution modelling and mapping.Phase 1 of the project involved a gap analysis with identified numerous new datasets, both published and unpublished, that are currently not incorporated into SPRAT profiles and distributions (see Table 5). This provided an opportunity to begin compiling and analysing this information to fill current data gaps, as well as identify targeted research needs for the future.Phase 2 of the project built on collaboration with data custodians to develop data sharing agreements for use of these datasets to construct spatial models to refine and update species distributions.Downloadable data and materials are a linked to in the 'online resources' section of this record.

在已知分布于北海洋生物区（North Marine Bioregion）的约80种被列入《环境保护与生物多样性保护法案》（Environment Protection and Biodiversity Conservation Act，EPBC）的受威胁与洄游海洋物种中，经与研究终端用户及专家磋商后，确定其中16种为优先保护物种。该优先物种组包含3种锯鳐、2种河鲨、儒艮（Dugong）、2种近岸海豚、6种滨鸟以及2种海龟。矮锯鳐与绿锯鳐存在最为严重的数据缺口，表明二者是北海洋生物区所选优先物种中认知程度最低的类群，因此成为研究的重点方向。按数据缺口严重程度排序，其余河鲨与锯鳐、近岸海豚、玳瑁海龟（Hawksbill Turtle）、儒艮、榄蠵龟（Olive Ridley Turtle）以及滨鸟依次位列其后。评估各类生存压力的相关性与影响的研究，被认定为所有优先物种均存在的研究缺口。本项目中发掘的新数据可填补全部16种优先物种的数据缺口，对这些数据集的分析也能提升物种分布地图的精度，但所有鲨类、锯鳐、玳瑁海龟以及近岸海豚仍需开展新的数据采集工作，以优化物种分布建模与制图所需的数据覆盖范围。本项目第一阶段开展了数据缺口分析，发掘了大量已发表与未发表的新数据集，而这些数据集目前尚未被纳入SPRAT档案与物种分布数据中（详见表5）。这为我们着手整理与分析此类信息以填补现有数据缺口，以及明确未来的针对性研究需求提供了契机。本项目第二阶段以与数据保管方的合作为基础，制定了数据集共享协议，以便利用这些数据集构建空间模型，从而优化并更新物种分布信息。可下载的数据与资料已在本记录的“在线资源”板块中提供链接。物种分布的GIS在线地图可通过以下WMS（Web Map Service）端点获取：https://geoserver.imas.utas.edu.au/geoserver/SDM/wms?request=GetCapabilities&service=WMS
