48  Determining material competition—grouped adjacent trees
          (1) The occurrence of material competition from grouped adjacent trees must be determined in accordance with this section.
Note: Material competition from grouped adjacent trees for a narrow or wide linear planting could occur where there is:
                         (a) a single occurrence of grouped adjacent trees;

                         (b) multiple occurrences of grouped adjacent trees; or

                         (c) either (a) or (b) in combination with individual adjacent trees.

            If only individual adjacent trees are present in the adjoining area, the project proponent must determine if material competition is determined in accordance with section 47.

          (2) The net length of impact of grouped adjacent trees is estimated in accordance with subsections (3) to (8).
          (3) The distance between the outermost stems of each occurrence of grouped adjacent trees must be measured along the long axis of the planting.
          (4) The length of impact of each clump must be determined by adding 30 metres to the distance determined in subsection (3).
          (5) The length of impact of each occurrence of an individual adjacent tree is taken to be 30 metres.
          (6) The gross length of impact of the adjacent trees is determined by adding together the distances specified in subsections (4) and (5) for all grouped and individual adjacent trees.
          (7) If the planting is a narrow linear planting where:
           1.     there are adjacent trees on opposite sides of a narrow linear planting; and
           2.     the length of impact of these adjacent trees overlaps;

       then:
           1.     the distance of the overlap along the long axis of the planting must be measured; and
           2.     the distance determined in paragraph (c) must be halved to give the overlap adjustment; and
           3.     the overlap adjustment calculated in paragraph (d) must be subtracted from the gross length of impact determined in subsection (6).
          (8) The net length of impact must:
           1.     for a narrow linear planting—be the length determined in accordance with subsection (6) and, if relevant, subsection (7); or
           2.     for a wide linear planting—be the length determined in accordance with subsection (6).
          (9) If the net length of impact of adjacent trees is:
           1.     for a narrow linear planting—more than 20% of the length of the long axis of the planting; or
           2.     for a wide linear planting—more than 20% of twice the length of the long axis of the planting;

       then the adjacent trees are taken to cause material competition for the planting.
Note: Adjacent trees are taken to impact the entire width of a narrow linear planting, but only taken to impact one half of the width of a wide linear planting. Consequently, in paragraph (9)(b) the length of the long axis of the planting is doubled before calculating the
