Australian Wildlife Services has been working with ACT Parks and Wildlife Services and TAMS to develop some maps of the new proposed Molonglo River Reserve for inclusion in the MRR Plan of Management. The reserve covers the lower Molonglo River past Scrivener Dam almost all the way to the confluence with the Murrumbidgee River. The Plan of Management is currently in draft and will be made public for consultation later in the year.MRR

Estimating Kangaroo Populations – Maxent and GIS Modelling

Red Distr dynamic landcoverThere are extensive kangaroo population surveys undertaken in Australia throughout the kangaroo harvesting commercial zones. Population estimates from these areas are used to set yearly harvesting quotas to ensure a sustainable kangaroo population and industry. However, there are extensive areas outside of the commercial zone with kangaroos that are not included in these population estimates. There hasn’t been a national population estimate of kangaroo numbers in Australia since 1987 (Caughley et al 1987). Australian Wildlife Services is undertaking a project that will aim to utilise known population densities in the commercial zone to extrapolate to the un-surveyed areas for the red kangaroo, eastern grey kangaroo, western grey kangaroo. Extrapolation will be undertaken using ecologically based GIS modelling and Maximum Entropy Modeling (MAXENT – run through the Atlas of Living Australia’s Spatial Portal). Using climatic and physical environmental variables, Australian Wildlife Services is attempting to define why are kangaroos where they are and why some densities are greater than others. The aim is to produce a conservative population estimate of the three species in Australia.

Historical vegetation, waterways in Canberra region c1813

Canberra OdysseyAustralian Wildlife Services partnered with the Canberra Museum and Gallery (CMAG), the ACT Environment and Sustainable Development Directorate and ACT Surveyor-Generals Office to produce a series maps depicting how the vegetation and landscape of Canberra might have been like before European settlement based on observations by early explorers and surveyors.

The maps were part of the the 2113: A Canberra Odyssey exhibition open at CMAG between Sat 13 July – Sun 3 November 2013.

Title: “The state of vegetation, waterways and the general landscape in the Canberra region c1813 based on observations by early explorers and surveyors”.

The maps were developed in reference to Bill Gammage’s book “The Biggest Estate on Earth: How Aborigines Made Australia” with his interpretation of the Canberra Landscape under Aboriginal land management at the time of the first explorers as well as detailed surveyor maps produced by Robert Hoddle in 1832.

Buffel Grass Surveys, Angas Downs

Buffel grass presence / absence surveys began in June 2012 on Angas Downs IPA. The survey can be redone next year to show how buffel is expanding or not. It will be interesting to see how quickly it takes to increase from a few plants to a dense patch. If a fast increase in plant density is shown, controlling single plants may be beneficial. The rangers drive the tracks and roads and enter into Cybertracker where they see single plants, a few plants or dense patches. The survey will be finished in July 2012.

AWS has full GIS capability in house using ArcGIS (ArcMap, ArcInfo), Mapinfo, Manifold. We interface these programs with Google Earth for easy customer viewing and use. Our mapping and GIS work ranges from digitizing hand drawn maps, complex spatial model development and producing spatial wildlife density estimates. AWS also works with Cadastral and Topographic digital databases, Landsat and SPOT imagery and can provide vegetation and fire mapping services. And our GIS analyst is reasonably priced.
