To see if there were significant differences in the relative importance of the six
weeds over the two seasons or between maps , correlation coefficients were
calculated for cover values . The correlation coefficient will be close to 1 . 0 where

186 The cover data are important in four ways ; for assessing variation between
years , variation between maps , the relative and absolute importance of the
different species and the overall levels of total weed cover . The two to four - fold

The relative importance of the root - feeding invertebrates observed during this
study is shown in Table 3 . The most important herbivores were worms . Less
important were slugs , Collembola and Enchytraeidae . Least important
