Brief description
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 the Taroom Shire site in Queensland, Australia.
Pre-European benchmark-analogue vegetation: the site was originally a brigalow, Acacia harpophylla, mixed community associated with several overstorey species, including Eucalyptus coolabah, E. cambageana, Casuarina cristata, a range of understorey species, grassy woodlands and open forests.
Brief chronology of changes in land use and management:
- 1860: Area used for sheep grazing by shepherds
- 1870: Permanent fences established
- 1875: Start of continuous or set stocking with sheep
- 1880: Incursion of prickly pear started
- 1935: Prickly pear had been destroyed
- 1929-1932: Land clearance through ringbarking
- 1929-1932: Gradual increase in cattle numbers decline in sheep
- 1940-1955: Manual clearing of brigalow with axes issues with regrowth
- 1960-62: Brigalow pulled mechanically and soil ploughed
- 1962: Soil ploughed and sown to buffel grass pasture
- 1962-65: Continuous grazing with cattle on buffel grass pasture
- 1966-75: Soil ploughed and sown to wheat annually – cattle graze stubble
- 1976: Soil ploughed and sown to buffel grass pasture
- 1976-2000: Continuous grazing with cattle on buffel grass pasture
- 2001-10: Soil ploughed and sown to wheat annually – cattle graze stubble.
Lineage
Information is compiled by year from published and unpublished sources.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.
Data Creation
Step 1. Select a representative site in terms of soil and landscape, and pre-European vegetation community.
Step 2: Locate that site using google earth and record its co-ordinates in the VAST-2 Chronology Datasheet
Step 3: Review relevant literature for the site and region, compiling information on land use history and associated land management practices. Simultaneously record for same year effect and impact of those practices on vegetation condition.
Step 4: Identify a group of specialists with ecological knowledge about the site who can revive, validate and identify gaps in the chronology and the accuracy of the data.
Step 5: Translate the observations from step 4 into 22 separately accessed vegetation condition indicators.
Step 6: Circulate the results of scoring of the 22 indicators and their aggregates including the graphs to the specialists identified in the step 4.
Step 7: Send results to Richard Thackway for incorporation into the ACEAS portal.
