Abstract
    Seagrass protection and restoration targets are established because seagrass is used as a barometer of the Indian River Lagoon's health. Criteria for targets are that they must be scientifically defensible; ecologically achievable; objective, i.e., based on actual data, such as historical distribution; simple; and bounded by natural variability. Three levels of quantitative seagrass coverage targets are set: ( 1) potential = to a depth of 1.7 m, based on "healthy" areas of the lagoon; (2) historical = maximum extent of where seagrass has been mapped, largely based on 1943; and (3) critical minimum = maximum extent of where seagrass has been mapped in at least half of non-1943 mappings. These quantitative targets will be used to set water quality and polltant loading targets. Qualitative targets include seagrass and animal density, diversity, and productivity.
