Methods

Tree and shrub species rooted in the 10 m x 10 m plot will be listed, with a note on whether they are represented (see Appendix II) as canopy dominants (C), subdominants (S), intermediate (I), suppressed (U), shrub layer, saplings or seedlings (Figure 12). A species may be represented in more than one of these categories. Ten cells, each 40 cm x 40 cm, are selected at random using a different randomisation for each 10 m x 10 m plot; the cells are marked, for relocation, in their NE and SW corners. The diameter at breast height (dbh, measured with a tape to the nearest 0.1 cm at a height 1.3 m above the ground) and height (measured to the nearest 0.5 m using a hypsometer or poles) of up to ten trees or shrubs of >5 cm dbh will be recorded*; the individuals chosen are those nearest to the centre points of the ten randomly selected cells. If the plant is multiple-stemmed, the dbh and height of the tallest live stem are measured and the number of stems is counted and recorded. The distance, at a height of 1.3 m, between the approximate centre of the chosen stem and the centre of its associated random cell will be recorded. The measured stems should be marked with paint at 1.3 m, numbered and re-measured on subsequent occasions. If a stem dies between surveys, a replacement stem is selected from the same randomly selected cell using the procedure outlined above. Seedlings will be counted by species in the ten selected 40 cm x 40 cm cells. Seedlings can be individually marked if monitoring of survival is of interest and recording repeated annually if necessary.
