Table 2. Condition

Table 2. Condition classes, equivalent IWC wetland vegetation assessment scores and categories, and descriptions for the condition classes. Condition class Condition class description IWC wetland vegetation assessment score/category 1 Severely modified 2 Substantially modified 3 Moderately modified 4 Slightly modified 5 Largely unmodified Indigenous ground-layer flora absent, except for at most a very minor component of the most resilient species, and largely replaced by introduced species EVC degraded, with only a minor component of relatively resilient species of the original understorey/ground flora persisting Structure of the vegetation substantially altered Serious environmental weeds typically prevalent within at least part of the wetland site or significant ecological invasions are advanced Vegetation disturbed, but still readily identifiable as a particular EVC Extinction-prone species mostly displaced, but a substantial component of the indigenous understorey/ground flora persisting (at least as a range of species at low levels, or if only a few species, then at higher cover) Serious environmental weeds often present or otherwise significant plant invasions occurring (native or introduced) Some floral diversity losses within the vegetation presumed, but at most minor Weed invasions relatively minor System apparently remaining ecologically stable No major identifiable impacts on vegetation condition (structure or floristics) Vegetation apparently still relatively intact and ecologically stable (temporal and spatial variation remaining within the spectrum of possibilities anticipated for unmodified examples of the relevant system) Floral diversity losses minimal if any Serious environmental weeds absent 0–5 Very poor >5–9 Poor >9–14.5 Moderate >14.5–18.5 Good >18.5–20 Excellent 14

Floral diversity losses presumed minimal, if any No Presumed floral diversity losses at most minor No Floral diversity losses substantial, but a range of species persist at low cover or a few species persist at high cover No At least minor component of relatively resilient ground-layer species persisting No Yes Yes Yes Weeds negligible, serious environmental weeds absent No Serious environmental weeds at most very minor No If serious environmental weeds established, not dominant No Yes Yes Yes Yes Vegetation structure largely intact No Alteration of vegetation structure at most minor No Vegetation structure modified, but key components of at least one stratum conspicuous No Vegetation structure substantially altered, but key species of at least one strata persisting No Yes Yes Yes No indication of modified ecological processes No Indications of modified ecological processes at most minor No Indications of modified ecological processes at most moderate No Yes Yes Yes Yes Condition Class 5 Condition Class 4 Condition Class 3 Condition Class 2 Condition Class 1 Figure 4.
