Figure 1. Location of the 27 wetlands (black dots) containing the 41 monitoring quadrats in the Lake Muir-Unicup catchment (light grey 
line). Nature Reserves occurring in the catchment are also shown. 
Differences were further examined using two 
dimensional non-metric multidimensional scaling 
ordination (MDS in Primer v5.2.8) of the complete dataset 
and computing the distance quadrats moved in 
ordination space over the five year period. 
At several of the wetlands in the Lake Muir-Unicup 
catchment, regular measurements are taken of water 
depth and water chemistry as part of the Department of 
Conservation and Land Management's long term 
wetland monitoring project begun in 1978 (Lane & 
Munro 1981). 
Results 
The five broad wetland types sampled were closely 
correlated with geomorphological position and floristic 
composition (N Gibson, unpublished data). Of these the 
Baumea articulata basin wetlands were very species poor 
and the flats and riparian zones dominated by Baumea 
juncea were less floristically variable than other wetland 
types (Fig. 2a). 
The sample statistic from the ANOSIM analysis was - 
0.02 which was not significant (P = 0.97) indicating that
