Abstract: The rocky shores of the outer Kenai Peninsula are the home of three Sugpiaq native villages where the black chiton (Katharina tunicata) remains an important traditional subsistence food source. This benthic invertebrate is also a competitively dominant herbivore known to have dramatic impacts on the structure, dynamics, and diversity of the rocky intertidal. In collaboration with tribal members, this project will evaluate the relative roles of natural factors (predation, grazing, and natural variability) and anthropogenic impacts (Katharina harvest) in altering intertidal community structure. The project addresses the core GEM hypothesis of human versus natural impacts on the structure and productivity of coastal ecosystems. It will also provide two field seasons (2003 and 2004) of valuable baseline monitoring in the intertidal zone that could be continued in the future. Local tribes will be involved in both developing and carrying out research which will match the GEM commitment to community based science.
