•INTRODUCTIONThe University of Guam Marine Laboratory was asked by the U. S.Army Corps of Engineers to perform a survey of the biota of theproposed dock and harbor site at Colonia, Yap. The proposed site, onthe north side of Colonia Peninsula, includes approximately 200,000square feet of intertidal schistose rock and SUbtidal reef area,which extends from the present shoreline out to the edge of theexisting channel to the north (Figure l). The whole of the biota inthis area will be removed or covered by the dredging and fillingoperation required for the construction of the dock. In order toassess the significance of this disruption of the environment, theMarine Laboratory survey team wa s requested to make a reconnaissanceof the proposed dock site and to prepare a report which would includethe following information:PERSONNEL1. A description of the qualitative conditions of the marineenvjronment at the project site;2. Discussion of the dominant coral, fish, algal, and invertebratespecies found at the project site;3. Discussion of the abundance and distribution of corals,fishes. algae, and invertebrates at the project site;4. Discussion of the probable adverse effects of the projectson the marine resources found at the project site;5. Recommendations for avoidjng or mitigating adverse environmentalimpacts attributed to the project.Steven S.
