Point Intercept and Surface Observation GPS (SOG): A Comparison of Survey Methods - Lake Gaston, NC/VA

摘要

Plant biomass data are critical to many aquatic plant assessment efforts, particularly those involving adaptive management of aquatic plant problems, integrated plant management approaches, or ecosystem restoration. Unfortunately, current methods for aquatic plant biomass sampling have depended upon expensive, labor-intensive SCUBA techniques or utilization of large, heavy dredging equipment. While these methods are accepted by the scientific community and resource managers, their high costs preclude their use on many projects. As a result, quantitative data are often lacking or inadequate. Research is currently being conducted to explore and develop new sampling methods that could be employed to provide scientifically acceptable plant community assessment data in a cost-effective manner.
