Bushland Condition Monitoring

Assigning Weed Threat Ratings

 

All introduced species in the State florawere assigned a rating (1-5, using Table 1 above) for each of the new 12 weed habitat groups.

 

A rating of 1 was assigned to a species for a habitat group if it was considered unsuitable or unlikely for it. Species requiring permanent or seasonal inundation were assigned ratings only to groups 2, 10 and 11.

 

As funding was a small grant, weed ratings have been revised without exhaustive referencing of the literature, and have drawn on the unpublished observations of ecologists at NCS and  regional NRM officers in the weed consultation of 2012.

 

Two local publications were however, particularly useful:
