Measurement AquaticPlantDistrib Whole lake aquatic plant distribution index values based on local qualitative density estimates. Values: 1 – plant species rare, only observed in one or a few places; 2 – plant species common, although not dominant; 3 – plant species in scattered, sometimes dense patches, co-dominant with other plants; 4 – plant species dominates in thick, nearly monospecific patches; 5 – plant species growing very densely at the exclusion of other species, a pattern usually restricted to invasive non-native species; and 9 - plant species present but not assigned an index value.
