<br>The aim of this project is to compile land use and management practices and their observed and measured impacts and effects on vegetation condition. The results provide land managers and researchers with a tool for reporting and monitoring spatial and temporal transformations of Australia’s native vegetated landscapes due to changes in land use and management practices. Following are the details about Mulligans Flat Nature Reserve. </br><br> Pre-European benchmark-analogue vegetation: the site was originally woodlands on the deeper soils of the lower slopes and flats (<em>Eucalyptus blakelyi</em> and <em>Eucalyptus melliodora</em>) (McIntyre et al. 2010). </br><br> Brief chronology of changes in land use and management:<ul style="list-style-type: disc;"> <li>1819: Area managed by indigenous Ngunnawal people</li> <li>1826: Sheep grazing with shepherds commenced</li> <li>1860: Fences constructed - continuous stocking with sheep commenced</li> <li>1920: Fallen timber collected for firewood started</li> <li>1994: Mulligans Flat Nature Reserve established</li> <li>1995: Continuous stocking with sheep grazing ceased</li> <li>1995: Collection of firewood ceased</li> <li>1996: Kangaroo population begins to rapidly increase</li> <li>2006: Predator proof fence completed</li> <li>2008: Commenced annual removal of pest species of plants and animals</li> <li>2010: Commenced annual kangaroo cull.</li></ul></br>
