Does Botanical Diversity in Sewage Treatment Reed-Bed Sites Enhance Invertebrate Biodiversity?

Figure 6

PCA* of Biomass against all other Site-Specific Variables. From the PCA of Biomass of invertebrates across all reed-bed across all reed-bed sites, only bare substrate was found to be positively correlated, whilst age, area, soil depth, and plant species richness were found to be negatively correlated. All other variables measured did not affect species richness.
