Baseline biological survey of To'atuga reef : Samoa
Available Online

Lovell, Edward R.

2004
To’atuga Reef is located between 6.5-7.4 km (3.5-4.0 nautical miles) north or seaward of Apia Harbour (middle) on the north coast of Upolo Island, Samoa. It is an elongate ridge of reef extending in a NW–SE axis, with a broad reef top which ranges between 15-22m descending on a slope of 300 450 with vertical sections to a sand and rubble bottom at 35-40m. The reef top is characterised by a low topographic relief with the undulating contours of small ridges and depressions. This report provides a baseline description of the major habitat types and dominant fauna present on the reef. A basic inventory and description of the To’atuga marine environment is undertaken. Transects were used to detail the occurrence primarily of fish, coral, algae, mobile invertebrates and physical substrate types. Preliminary species inventories were compiled for hard coral and fish, with records of other benthos. General features of the habitat such as the surge environment, current, depth, bathymetric profile, community type and dynamics are described. Bathymetric assessment was aided by the profiling of the reef by South Pacific Applied Geoscience Commission (SOPAC) which provided a framework for site position and general reef assessment. Impacts of storms, coral bleaching, disease and the human impacts of recreational diving, fishing and anchoring are discussed and management recommendations made.

Merremia peltata, disturbance ecology, tropical cyclones and Samoa. The biology and ecology of Merremia peltata are not well understood. While some regard the species as an exotic invader of Pacific Island ecosystems (Meyer. 2000). others identify the plant as a native species likely to be harmful to native ecosystems (Whistler, 1995a. 2002) or as either native or ancient Polynesian introduction behaving invasively (Space and Flynn.(2002). In Samoa, this species occurs up to an elevation of around 300 meters (Whistler 1995a). and thus only affects lowland ecosystems. This species increases its distribution and abundance in two ways, either vegetatively. by sprawling into neighboring areas and rooting from its nodes or by seeds, although early research in the Solomons observed a low seed viability rate, and creeping may thus be its primary means of reproduction (Bacon. 1982). M. peltata has apparently been in the Pacific for hundreds of years (Whistler, pers. com.) but has only become invasive in the years following tropical cyclones Ofa (1990) and Val (1991) according to comments from local government officials. Disturbance thus appears to be an ecological contributing factor to this invasion.
