(1) For each survey plot, calculate the value of each indicator or sub-indicator for ecosystem condition in the survey plot in accordance with the following table.
| Indicator or sub-indicator | How to calculate the value of the indicator or sub-indicator in a survey plot | |
|---|---|---|
| (a) | canopy height of native vegetation (in metres) | Calculate the value of this indicator as the average height of the measured trees |
| (b) | crown cover from native plants in the canopy layer (as a percentage) | Using the data obtained from the point intercept method, calculate the value of this indicator by:a. adding the number of sample points that fall beneath crowns on native plants in the canopy layer in the survey plot; andb. multiplying the result by two to derive the percentage crown cover |
| (c) | crown cover from native plants in the mid-storey layer (as a percentage) | Using the data obtained from the point intercept method, calculate the value of this indicator by:a. adding the number of sample points that fall beneath crowns on native plants in the mid-storey layer in the survey plot; andb. multiplying the result by two to derive the percentage crown cover |
| (d) | crown cover from plants in the canopy layer provided by non-native plants (as a percentage) | The benchmark value of this indicator is 0% |
| (e) | crown cover from plants in the mid-storey layer provided by non-native plants (as a percentage); | The benchmark value of this indicator is 0% |
| (f) | ground cover from sub-category A1, A2 and A3 plants as a proportion of total ground cover from category A plants | The benchmark value of this indicator is 100% |
| (g) | ground cover from sub-category A4 and A5 plants as a proportion of total ground cover from category A plants. | The benchmark value of this indicator is 0% |
| (h) | sub-indicators for native species richness index—number of native species of each of the following life forms:a. tree;b. shrub;c. vine;d. grass;e. herbaceous vascular plant species other than grasses | Using the data obtained from the point intercept method, the quadrat method and the plot survey method, for each survey plot tally the number of native species by life form to create a separate value for each sub-indicator |
