The methods used in this survey were the same as those used in the initial survey, with the following modifications. (For a description of the methods used originally, please access, Initial Survey - Methods.)

1. A 20 metre square was laid out in each of the four representative regions of the project site. The vegetation inside each of the squares was then sampled. The position of these squares did not exactly correspond to the position of the original 20m squares sampled in the initial survey, although they were within the same representative regions.

2. The height of trees in Squares 1 and 2 was measured directly using a klinometer (see Appendix A), instead of being estimated as in the original survey.

3. Ground vegetation inside the squares was sampled within 2m² quadrats (Plate 10). Ten random quadrats were sampled inside each of the 20m squares (See Appendix B for explanation of random location of quadrats). In the original survey, it was impossible to randomly locate quadrats in Squares 1,2 & 4 due to the impenetrable nature of the undergrowth (Plate 11). They were instead located to cover as much of the area of the square as possible. With the removal of the Rhododendron undergrowth, random location of all the quadrats became possible.
