The goal of the study is to examine the important reef process of herbivory in
Dry Tortugas National Park.  We will be surveying sites both inside and outside
of the newly established no-take Research Natural Area so that changes in
trophic structure and herbivory rates resulting from protection from all
fishing can be evaluated over time.
Information to be Derived
Percent cover and biomass of macrophytes, abundance and size of herbivorous
fishes, density of herbivorous sea urchins, estimates of grazing intensity,
rugosity of the substratum, percent live coral cover, and percent cover by
other invertebrates.
We will collect data via SCUBA at randomly selected sites within the two most
abundant habitat types, low relief hard bottom, and patch reef, as well as some
areas of special concern to the DTNP Division of Resources.
Platforms used; MV Fort Jefferson and small vessel MV Halimeda
