- NATURAL RESOURCE MANAGEMENT VISION FOR THE NORTHERN AGRICULTURAL REGION OF WESTERN AUSTRALIA
Menu
These data show the proportion of land in the Northern Agricultural Region that is allocated to protected areas (DBCA-SLIP; provided by NACC NRM), agriculture (DPIRD Client-Property-Event Database, property statistics by CAR; provided by DPIRD) and other land uses (total area of the NAR [ha] – area of nature reserves – area of agricultural land). These data will be updated annually by checking with DBCA for information about changes to the conservation estate in the region.
These data show the total number of threatened species and threatened ecological communities. Lists of all threatened plant and animal species and threatened ecological communities in the NAR, and information on their conservation status and distribution, were generated for the region as described in the species lists provided on the Biodiversity Page. These data will be updated every five years by reviewing the species lists in consultation with DBCA. Note that a plant or animal’s status as threatened or priority species is evaluated on an ongoing basis and may change through time. Graduating from a priority species, where there is insufficient knowledge about the conservation status of the plant or animal, to a threatened species can be a good thing in that the species can then receive more targeted management.
These data were obtained from the Australian Threatened Species Index 2020 (to 2017) for terrestrial birds, which uses data provided by Birdlife Australia. These data were collected in Western Australia but calculated by averaging the number of Carnaby’s Black-Cockatoos counted at known roost sites in the region during the annual Great Cocky Count. More recent data were obtained from Birdlife Australia’s Great Cocky Count Report 2019. Data presented here are for roost sites located within the NAR.
These data were obtained from the Australian Threatened Species Index 2020 for terrestrial birds, which uses data provided by the National Malleefowl Recovery Team. These data were collected in Western Australia but not specifically in the Northern Agricultural Region. Trajectories were calculated by averaging the number of active Malleefowl mounds along a series of fixed-route transects surveyed between 1995 and 2017.
These data were obtained from the Australian Threatened Species Index 2020 for marine birds, which uses data provided by the Dr Chris Surman of Halfmoon Biosciences. These data were collected on the Houtman Abrolhos Islands. Trajectories were calculated by averaging the number of active Lesser Noddy nests located along a series of fixed-route transects surveyed between 1989 and 2014. The surveys are ongoing but results have not been published since 2014.
Curlew Sandpiper Calidris ferruginea, Great Knot Calidris tenuirostris, and Red Knot Calidris canutus, Red-necked Stint Calidris ruficollis, Grey Plover Pluvialis squatarola and Greater Sand Plover Charadrius leschenaultii. These data were obtained from the Australian Threatened Species Index 2020 for shorebirds, which uses data provided by Birdlife Australia. All of the species in the shorebird Index occur in Northern Agricultural Region but none of the data shown were collected in the NAR. Trajectory presented is adapted from the Threatened Species Index visualiser tool and aggregates data for all the shorebird species and the figure shows the average trajectory over time (blue) and the 95% confidence interval (grey).
These data were obtained from the Australian Threatened Species Index 2020 for marine mammals, which uses data provided by the South Australian Government. Trajectories were calculated by averaging the number of Australian Sealion pups counted at standardised sites between 1989 and 2017.
These data were obtained from the Australian Threatened Species Index 2020 for medium-sized mammals, which uses data provided by the Department of Biodiversity, Conservation and Attractions. These data were collected in Western Australia but not specifically in the Northern Agricultural Region. Trajectories were calculated by averaging the number of Chuditch caught in cage traps along road transects at standardised sites surveyed between 1996 and 2017.
These data were obtained from the Australian Threatened Species Index 2020 for plants, which uses data provided by the Department of Biodiversity, Conservation and Attractions. These data were collected in the Northern Agricultural Region. Trajectories were calculated by averaging the number of plants counted at standardised sites surveyed between 2012 and 2017.
