  • Dataset Abstract
    This dataset provides cover, canopy height, and species richness estimates for seagrass communities throughout Shark Bay, as well as ancilliary physical data. These data will be used to determine spatial patterns of seagrass loss and recovery, as well as recovery rates and succisional changes in community composition, if present.

  • Methods
    Sampling Description
    Percent cover data, estimated using a mean of three 60cm x 60 cm quadrats. Once the first quadrat is placed and measured, the quadrat is flipped end over end 3 times and a second reading is taken. This is repeated a third time. The quadrats are flipped towards the bow of the vessel.
