Mulligans Flat Nature Reserve, ACT. VAST-2: Tracking the Transformation of Australia's Vegetated Landscapes 

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.

Pre-European benchmark-analogue vegetation: the site was originally woodlands on the deeper soils of the lower slopes and flats (Eucalyptus blakelyi and Eucalyptus melliodora) (McIntyre et al. 2010).

Brief chronology of changes in land use and management:

• 1819: Area managed by indigenous Ngunnawal people
• 1826: Sheep grazing with shepherds commenced
• 1860: Fences constructed - continuous stocking with sheep commenced
• 1920: Fallen timber collected for firewood started
• 1994: Mulligans Flat Nature Reserve established
• 1995: Continuous stocking with sheep grazing ceased
• 1995: Collection of firewood ceased
• 1996: Kangaroo population begins to rapidly increase
• 2006: Predator proof fence completed
• 2008: Commenced annual removal of pest species of plants and animals
• 2010: Commenced annual kangaroo cull.

 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. This work was funded by ACEAS, a facility of Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project. 

Data not provided. 

Information is compiled by year from published and unpublished sources. It includes qualitative and quantitative observations. It represents a structured narrative. Once compiled this narrative is translated into 22 indicators of vegetation condition which are grouped into three condition components: vegetation structure, species composition and regenerative capacity.

The pdf is a compilation of historical land use management of the site using 12 core attributes which describes the transformation of a native vegetation community relative to its reference state.

The spreadsheet provides the scores on the effects of the land management practices on the 22 indicators. Each indicator is scored from 0 to 1 for each year of the historical record; where 1 represents the reference state for each vegetation and environmental indicator, and 0 is where that vegetation indicator and/or ecological function is absent. The spreadsheet is used to sum and weight the indicators into the respective components of vegetation condition i.e. regenerative capacity, species composition and vegetation structure. The weighted transformation scores are then added to produce a single transformation index of vegetation condition for each year of the historical record. The results could be graphed and annotated to show the response of the plant community under different land use and management regimes.
