Method

Monitoring is conducted at 25 fixed sites twice annually (late May to early October) during the growing season. At each fixed site, a square meter quadrat is haphazardly thrown within the vicinity of submerged aquatic vegetation (SAV). Data from four quadrats is collected per site. This data includes species present, Braun-Blanquet for SAV and algae composition (by species and overall). Within each quadrat, blade length for 4 random representations for each species is conducted. Site are assessed using a modified 6-point Braun-Blanquet scale (0-5): 0 - No SAV, 1 - < 5%, 2 - 5 to 25%, 3 - 25 to 50%, 4 - 50 to 75%, 5 - 75 to 100%. Other qualitative data found within a quadrat are recorded including epiphyte density, sediment type, and presence of fish, crab, etc.
