Fig. 4.

Box plot showing the relationship between EQR_avg and total submerged macrophytes in LCB1 and LCB2 lakes. The horizontal line separates ‘good’ and ‘high’ status from ‘less than good’ status. Total submerged macrophyte abundance is calculated in classes ranging from 1 to 5. The macrophyte abundances can be interpreted as follows: submerged macrophyte abundance ≥1.5 – submerged macrophytes are present, at least in low-to-moderate amounts; ≥2.5 – lakes in a macrophyte-dominated state; and ≥3.5 – a high abundance of submerged macrophytes. Different letters indicate abundance classes that are statistically different (p ≤ 0.05).
