Title: Vegetation: Natural Temperate Grassland Community
Custodian: ACT Government, Department of Urban Services, Environment ACT
Jurisdiction: Australian Capital Territory
Abstract:
Natural grassland is a native ecological community that is dominated by native species of perennial grasses. There is also a diversity of native herbaceous plants (forbs) present. An important characteristic of the community is that it is naturally treeless, of has less than 10% projective foliage cover of trees, shrubs and sedges in its tallest stratum. In the ACT, natural temperate grassland occurs up to an altitude of 625 m asl. Native grassland communities in the south-east of the continent and Tasmania with a mean annual rainfall of 500 to 1000 mm are referred to as 'natural temperate grassland' of 'lowland native grassland'. In accordance with section 21 of the Nature Conservation Act 1980, Natural Temperate Grassland was declared an endangered ecological community on 15 April 1996.

Beginning date: 1992-01-01
Ending date: Current
Progress: Complete
Maintenance and update frequency: Not Known
Access constraints:
DIGITAL restricted - requests required in writing. NON DIGITAL Action Plan $5.00
Lineage:
Original boundaries were digitised from 1:25 000 maps, further refinement was include from digitised boundaries on 1:10 000 maps. Currently all boundaries are being GPS'ed (with differential) in the field, some of the boundaries have been included into this coverage but not all - new boundaries should be completed Dec 1999.
Positional accuracy:
Plus or minus unknown metres down to plus or minus 5 - 10 metres
Attribute accuracy:
Currently attributes only include Site no., Site name, and Site ID, new version will be linked to the Grassland database.
Logical Consistency:
This layer is not very consistent, boundaries are only approximate, for detailed information contact the custodian. Further work required
Completeness:
Complete - all known sites identified.
