This is because Wetland 2 was mostly <br />dominated by large monocultures of non-native species including reed canary grass and narrow-leafed <br />cattail (Typha angustifolia). Within Relevé 4, where there was a higher species richness and diversity index <br />score (more equal cover of species), all index scores were substantially higher than those in the other <br />Relevés. Overall, the total comprehensive FQI scores and individual Relevé FQI scores are low, indicating <br />Wetland 2 is has a low-quality plant community and species assemblage.
