Dataset AbstractBraun Blanquet surveys determining frequency, abundance, and density for seagrass and macroalgae made during visits to TS/Ph 7a, 8-11. Our long term research program focuses on the following central objective: Regional processes mediated by water flow control population and ecosystem level dynamics at any location within the coastal Everglades landscape. This phenomenon is best exemplified in the dynamics of an estuarine oligohaline zone where fresh water draining phosphorus-limited Everglades marshes mixes with water from the more nitrogen-limited coastal ocean.

MethodsSampling Description
The sites TS/Ph 7a, 8, 9, 10 and 11 were chosen as the main LTER sampling sites in Florida Bay, because they were sites where a lot of historical data were collected and they also are representative of the salinity gradient across Florida Bay. We are assessing frequency, abundance, and density at these sites because of the importance of the makeup of the ecological communities at those sites.
Method Step
Description
A rapid, visual assessment technique developed early in the 20th century by the plant sociologist Braun-Blanquet was used to assess frequency, abundance, and density of seagrass and macroalgae. This method is very quick, requiring only minutes at each sampling site; yet it is robust and highly repeatable, thereby minimizing among-observer differences. At each permanent seagrass monitoring site, a 50 m long transect was established at the beginning of the study period by driving steel rods into the substratum at both ends of the transect. At each mapping site, a 50 m transect was set up by extending a meter tape along the bottom in an up-current direction. Ten quadrats (0.25 m2) were placed along each transect at pre-determined random distances from one of the marker rods. A new set of random numbers was chosen before each visit to a site. Each quadrat was examined by divers using SCUBA. All seagrass species occurring in the quadrat were listed, and a score based on the cover of the species in that quadrat was assigned (0= Taxa absent from quadrat; 0.1= Taxa represented by a solitary shoot, less than 5% cover; 0.5= Taxa represented by a few (less than 5) shoots, less than 5% cover; 1= Taxa represented by many (greater than 5) shoots, less than 5% cover; 2= Taxa represented by many (greater than 5) shoots, 5 - 25% cover; 3= Taxa represented by many (greater than 5) shoots, 25 - 50% cover; 4= Taxa represented by many (greater than 5) shoots, 50 - 75% cover; 5= Taxa represented by many (greater than 5) shoots, 75 - 100% cover). Cover, as defined for this purpose, is the fraction of the total quadrat area that is obscured by a particular species when viewed from directly above.
