Thresholds
|
Criteria that are broadly applicable
|
1a. The minimum patch size is 0.5 hectare;
AND
1b. The canopy layer contains Grey Box (E. microcarpa) as the dominant or co-dominant tree species;
AND
1c. The vegetative cover7 of non-grass weed8 species in the ground layer is less than 30% at any time of the year.
|
Additional criteria that apply to smaller woodland patches
(0.5 to <2 ha in area) with tree crown cover >10%
|
2a. At least 50% of the vegetative cover in the ground layer comprises perennial native species at any time of the year;
AND
2b. 8 or more perennial native species (6 or more in the Flinders Lofty Block Bioregion of South Australia) are present in the mid and ground layers at any time of the year.
|
Additional criteria that apply to larger woodland patches with a well developed canopy (2 ha or more in area)
|
3a. At least 8 trees/ha are hollow bearing or have a diameter at breast height of 60 cm or more10;
AND
3b. at least 10% of the vegetative ground cover comprises perennial native grasses at any time of the year;
|
OR
|
4a. At least 20 trees/ha have a diameter at breast height of 12 cm or more;
AND
4b. at least 50% of the vegetative cover in the ground layer comprises perennial native species.
|
Additional criteria that apply to patches where the canopy is less developed or absent (derived grassland)
(≥0.5 ha in area)
|
5a. Woodland density does not meet criteria 3a or 4a, or is a derived grassland with clear evidence that the site formerly was a woodland with a tree canopy dominated or co-dominated by E. microcarpa;
AND
5b. At least 50% of the vegetative cover in the ground layer is made up of perennial native species at any time of the year;
AND
5c. 12 or more native species are present in the ground layer at any time of the year.
