TABLE 4: VALUES AND DESCRIPTORS FOR THE LOCATION (L) MODIFIER

            LOCATION DESCRIPTORS                                  MODIFIERS (L)
              Perfect suitability                                     1.0
              Could be better located but no problems                 0.9
              Minor problems, e.g. lifting paving                     0.8
              Species unsuited or causes problems                     0.7
              Species unsuited and causes problems                    0.6
              Species unsuited and causes major problems              0.5
              Species unsuitable                                      0.4


 Accordingly, in 1991 the method was modified by using the formula for a cone (1/3 or2h) to calculate
 tree volume and the use of the volume modifier (V) was discontinued. In the modified method, tree
 value can be determined using the formula:

          VALUE ($) -- TREE VOLUME x BASE VALUE x (E) x (FV) x (L)

 For consistency, when determining the base value under the modified method, the formula for a cone
 should be used. The modified method tends to give a lower value for smaller, short-lived or inferior
 quality specimens.
