Figure 2. The relationship between a) richness of survey native
macrophyte species and Elodea canadensis lake percentage of
occurrences at all the study lakes (Loughs). Kilturk Lough was
identified (blue star) as an outlier and subsequently excluded in the
second plot analysis. The relationship between richness of native
macrophyte species and E. canadensis abundance at each lake
sampling points in lake Group 1 (b); lake Group 2 (c) and
(d) lake Group 3 . Pearson correlation coefficients, LOESS line
trend and significance for ach analysis are indicated at each plot.
