total ground cover from category A plants.                               a. adding the number of sampling points in the sampling plot assigned to each of subcategory A1, A2, A3, A4 and A5; and

                                                                                                                                                 b. dividing the sum for each subcategory by the total number of sampling points in the sampling plot assigned to category A plants.

(g)                                                                                                                                          Step 2

                                                                                                                                             Using the data obtained from the quadrat method, calculate the percentage of ground cover from category A plants that is that is provided by plants from each of subcategories A1, A2, A3, A4, and A5 for a sampling plot by:

                                                                                                                                                 a. for each quadrat—calculating the percentage of ground cover from category A plants that is provided by plants from subcategories A1, A2, A3, A4 and A5 in the sampling plot; and

                                                                                                                                                 b. for each subcategory—adding the percentage from each quadrat in the sampling plot and divide by the total number of quadrats in the sampling plot.

                                                                                                                                             Step 3

                                                                                                                                             Calculate the value (as a percentage) for ground cover from category A plants that is provided by plants from subcategories A1, A2, A3, A4 and A5 for the sampling plot using the means from steps 1 and 2 by:

                                                                                                                                                 a. for each subcategory—adding the percentage derived from Step 1 to the percentage derived from Step 2; and

                                                                                                                                                 b. dividing the result by 2.

(h)  native species richness index by life form (native tree, shrub, vine, grass and herbaceous vascular plant species other than grasses)'  Using the data obtained from the plot sampling method, calculate the native species richness index value as follows:

                                                                                                                                             Step 1

                                                                                                                                             For each permanent sampling plot, calculate the overall native species richness index reference value for the sampling plot by adding the relevant benchmark values for all the sub-indicators—numbers of species of trees, shrubs, vines, grasses and other herbaceous vascular plant other than grasses (herbs).

                                                                                                                                             For example: if the relevant benchmark values are 3 species of trees, 3 species of shrubs, 0 species of vines, 2 species of grasses and 2 species of other herbs, the overall compositional reference value is calculated as = 3 trees + 3 shrubs + 0 vines + 2 grasses + 2 herbs = 10.

                                                                                                                                             Step 2

                                                                                                                                             For each permanent sampling plot, calculate a native species richness contribution value for each sub-indicator covered by the native species richness index indicator by comparing the number of native species in each life form in the sampling plot with the relevant benchmark value of the corresponding sub-indicator.

                                                                                                                                             If the number of native species in a life form is less than or equal to 150% of the relevant benchmark value, the native species richness contribution value for that life form for the sampling plot is the number of native species recorded.

                                                                                                                                             If
