Weed Threat Ratings Update 4

Assigning BCM communities to Weed Habitat Groups

Previously, Weed Threat Region could be assigned after field data collection, at the point of data entry, purely based on location. The revised procedure will require the decision to be made by the field officer on the basis of the

rainfall,
soil type
understorey type criteria described above,

and recorded on the datasheet. As a guide, in the following table, each BCM community has been assigned to a weed habitat group. Where a BCM community could potentially occur in more than one of the new weed habitat groups, it was assigned to the one where the BCM community most frequently occurs.

The complete list of 1773 weed species and their ratings across the 12 new Weed Habitat Groups can be found here. Or you can browse a list on the next page here.
