A

It should be noted that this data is now somwhat dated! Grid weed coverage species from States with 4 classes (present{2}, low{1}, med{2}, high{3}) plus no data.

relative density rating derived by multiplying the percent of the total number of species in each density class by the density weight (in {} ) and summing them.

Polygons ->250m grid; resampled (mean) to 5km cell.

Data: Weeds of National Significance ( NLWR / Thorn and Lynch, 2000, The determination of weeds of national significance, 1:12.5m and 1:50m)

Data are available as:

  • continental maps at 5km (0.05 deg) cell resolution for the ILZ;
  • spatial averages over CRES defined catchments (CRES, 2000) in the ILZ;
  • spatial averages over the AWRC river basins in the ILZ.
