  Using the data obtained from applying sections 5 to 8, calculate the indicator values of the ecosystem condition for the activity area in accordance with the following table:

     Indicator                                                                                                                               How to calculate the value of the indicator in a permanent sampling plot

                                                                                                                                                 b. 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)                                             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 non-native plants in the canopy layer in the sampling plot; and
