  • Methods
    Sampling Description
    This study was conducted on Cross Bank, a shallow (< 30 cm deep), narrow (< 50 m wide) seagrass-covered car- bonate mud bank in east-central Florida Bay. Five sites, spaced 600 m from one another, were used for sampling, easch with a bird roost and control spaced 10m from each other. The roost consisted of PVC pipe with a 5 cm x 10cm x 10cm block of wood on top.The control consisted of a sharped PVC pipe to deter bird roosting.

    Method Step

    Description
    The species composition, leaf biomass and short shoot (SS) density of the seagrass bed aroundeach control and fertilization treatment stake was recorded at the five sites on Cross Bank. For each sampling, quadrats(10 cm x 10 cm) were placed within 50 cm of the marker stakes. The number of short shoots of each seagrass species were counted, and the seagrass leaf biomass within the quadratswas harvested. These leaves were separated by species, washed in 10% V/V HCl to remove epiphytes, and dried to a constant weight. Leaf biomass, commonly called standing crop in seagrass liter- ature, and short shoot (SS) density, were expressed on a m-2 basis. Number of sampling replicates is dependent on smapling year and collector.

    Instrumentation
    10cm2 PVC quadrats
