Lake Pontchartrain Ruppia and Vallisneria biomass, shoot density, canopy height, flowers, seeds at four locations (2000-2001)

Seasonal variation of density and biomass, duration and abundance of seed production, and length of growing season will be established. Dry grams of shoot to root ratio will be compared for each species (Vallisneria and Ruppia), total biomass (dry mass grams) and plant nutrient level.
