Interpretive Summary: While field survey techniques for terrestrial plants are well-documented and standardized, methods for survey of aquatic plant distribution and abundance are not standardized. This manuscript presents specific suggestions on how to survey the distribution and abundance of submersed, floating and emergent aquatic plants for research on aquatic plant management. For each technique, specific examples of previous publications are provided as examples on how these methods are used and statistically analyzed.

Technical Abstract: Proper survey methods are essential for objective, quantitative assessment of the distribution and abundance of aquatic plants as part of research and demonstration efforts. For research, the use of the appropriate method is an essential part of the scientific method, to ensure that the experimental data collected can be appropriately tested statistically to determine whether not the hypothesis may be rejected. Methods for the assessment of species distribution, community composition, biomass abundance and density for submersed, floating and emergent macrophytic vegetation are reviewed, with examples provided for each method for further consideration.
