Total number of individuals and morphospecies (shown in brackets) of surface dwelling invertebrates caught in pitfall traps (n = 3) at each 11 of the 13 sampling point.

Main Orders are presented individually while less abundant orders (Isopoda, Dermaptera, Hemiptera, Diplopoda,Mantodea and Opilionidae) were pooled and presented in a single group called Others. The values for the reference points were averaged to give an overall reference value. No data was obtained for Ref 3 sampling point due to the loss of all pitfall traps due to animal trampling.
