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 Big Scrub, Tintenbar site.
Pre-European benchmark-analogue vegetation: The site was originally lowland subtropical rainforest on basalt-derived and alluvial soils below 250 m asl and further than 2 km from the coast.
Brief chronology of changes in land use and management:
- 1788: Indigenous land management - Goori people
- 1823-25: Explorers Oxley followed by Rous traversed the area
- 1842: Cedar getters ‘moved in’
- 1870: Portion or survey plan prepared for the Tintenbar property
- 1880: Camphor was planted as a shade tree in Lismore 1880s along streets
- 1885: Brush had been largely selected and slightly cleared
- 1900: Clearing done with brush hooks. Small trees were cut down with an axe and large trees were cut down using a cross-cut saw. Brush and fallen timber was burnt
- 1900: Basalt rock removed from paddocks and placed around borders as field stone fencing, Paddock cleared of floaters so it could be ploughed
- 1901: Aggressive pasture grasses established. Initially this was Paspalum
- 1901-1978: Dairying and pasture improvement - mainly Kikuyu and fertiliser added
- 1968: Observed incursions of camphor in creeks and gullies but not removed or controlled
- 1979: Changed from dairying to beef cattle production
- 1980-87: Cattle removed - destocked
- 1981-87: Observed incursions of weeds into the former dairy pasture including lantana, barna or elephant (Pennisetum purpureum) grass and tobacco bush and some camphor but not removed or controlled
- 1988: Commenced agisting cattle
- 1990-93: Agisted horses and cattle
- 1993: Ceased agisting cattle and horses
- 1994-2011: Dense stands of camphor left unchecked.
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Information is compiled by year from published and unpublished sources.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.
