Coral atolls are natural laboratories within which to examine ecological processes (Sachet, 1967; Lee, 1984). They are often isolated, in some cases little disturbed, and have a geologically recent history of terrestrial plant colonisation. Reef islands around the rim of most atolls are Holocene in age. They are composed of biogenic skeletal sediments and have developed since reef growth caught up with sea level which stabilized after post-glacial sea-level rise. Plant colonisation of most of these islands must have occurred over a period of no more than 6000 years.
In a typical High Island coral reef complex of French Polynesia (transect of Tiahura, Hoorea Island, Society Archipelago!, 73 species of decapod Reptantia and stomatopod crustaceans were collected. Over 9 stations localised along the transect, 3 different units of hard coral substrate of simi1ar volume (about 17 litres each), were sampled at each station. The results are discussed from two aspects : the first shows that at least 50 carcinologic species occur within the cavitary biotopes ; 16 species (mainly Xanthid crabs), represent more than 90% of all collected individuals.
Tongatapu, like Tahiti, was visited by many early
European navigators and was one of the first of the South
Pacific islands to be charted in any detail. Though it was
discovered (and named Amsterdam Island) by Tasman in
January 1643 (Sharp 1968, 152-158), the first comments on
the sand cays of the surrounding reefs were made by Cook
during his second voyage, with the Resolution and Adventure,
in October 1773. On this occasion Cook spent less than a
week at Tongatapu, anchored in the northwest, and commented
During the period February 13 to 20, 1973, a visit was made to Canton Island for the purpose of conducting a preliminary survey of marine turtle nesting populations. Although previous investigators have described the sea birds (Buddle, 1938; Murphy G., 1954), insects (Van Zwaluwenburg, 1943, 1955), and vegetation (Hatheway, 1955), very little is known about the marine environment of Canton or the other seven atolls (Enderbury, Birnie, Phoenix, Sydney, Hull, Gardner and McKean) which comprise the Phoenix group.
Recent studies have shown that many coral reefs are capable of
yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala,
1981; Munro, 1987). There are, however, no estimates for the
productivity and yield of fishes associated with coral reefs in
French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

Coral reefs are vital ecosystems, providing a source of income, food arid coastal protection for millions of people; arid recent studies have shown that coral reef goods and services provide an annual net benefit of US$30 billion to economies worldwide
France has an important role and extensive responsibilities in protecting the world's oceans. It is the world's third
largest maritime power with an Exclusive Economic Zone (EEZ) covering 11 million km2, and has the fourth
largest area of coral reefs representing biodiversity hotspots.
According to a recent Nature Conservancy assessment, only 1% of marine areas (as against 12 % of all land
areas) are officially protected today, despite government commitments under the UN Convention on Biological
Microbenthos and macrobenthos were quantitatively studied at 62 stations distributed regularly over the Uvea Atoll lagoon (850 km2). Sampling was performed using both SCUBA and a 0.1 m2 Smith Mclntyre grab. Mean estimates of ATP, chlorophyll a and phaeopigments were 297.3ng/cm2, 77.01 mg/m2 and 35.28 mg/m2
respectively. The mean macrobenthic biomass was 4.14 gAFDW/m2 of which the macrophytobenthos accounts for 39%. The benthic biomass decreased from the coast to the deepest parts of the lagoon. Macrophytes were most abundant in the coastal area
Species which have been assessed for extinction
risk are on average moving closer to extinction.
Amphibians face the greatest risk and
coral species are deteriorating most rapidly in
status. Nearly a quarter of plant species are estimated
to be threatened with extinction.

More than 20 cetacean species are known to exist in the
Pacific Islands Region, which encompasses the U.S. Exclusive
Economic Zone, or EEZ (waters out to 370 km from shore) around
the entire Hawaiian Archipelago. Johnston Atoll. Kingman Reef and Palmyra Atoll. Baker and Howland Islands. Jarvis Island. American Samoa. Wake Island, Guam, and the Commonwealth of the
Northern Mariana Islands, totaling some 5.8 million km2 of ocean.
Many of the species present are poorly studied throughout their
Fishers have changed their methods from wading in the shallows to the use of sail and paddle canoes, and dinghies with outboard motors. This has resulted in greater coverage of the area where sea cucumbers live, more regular fishing, access to remote areas and the capacity to transport greater catches. Loss of much larger numbers of sea cucumbers from many areas as a result of this increased fishing pressure reduces the chances of adults remaining at densities high enough for effective reproduction.
Cheloniid turtles are characterised by a complicated life history: their eggs are laid on warm beaches; hatchling sex is determined temperature dependent sex determination during
embryonic development; lack of parental care; hatchlings are imprinted to the natal area; hatchlings disperse to feed on plankton in the pelagic environments followed by inshore
recruitment to feed on benthic organisms; immature turtles have slow growth and delayed maturation; adults migrate to breed in their respective natal area; they lay multiple clutches in

Biodiversity tends to be at a maximum in the
equatorial region in the west of the Pacific Islands
area, and decreases markedly towards the east. For
example, the number of naturally occurring species of
animals and plants is much greater in the Solomon
Islands than in Tahiti. This is also true of the marine
environment, where fish and invertebrate species,
including corals, are far more numerous in the west
of the sub-region than in the east.

The Tokelau Islands consist of three atolls (Atafu, Nukunonu and Fakaofo) approximately 500 km north of Western Samoa. Their numerous islets are formed mainly of coral sand and rubble with no standing freshwater. Sixty-one plant species have been recorded, 13 of these being introduced and 10 being adventives. There are three vegetation zones, the beach, the beach-crest, and the interior coconut/fern zone with the physiognomy of a humid tropical forest. Marine invertebrates have not been studied.
Conservation biology involves protection and management of biodiversity (Metfe and Carroll 1994). This integrated discipline requires both an understanding of an ecosystem and its associated threats, as well as an understanding of the management of the system as a resource. In order to
develop management techniques that can limit resource degradation, we need a clear understanding of the role of threats to the resources. The focus of this dissertation is assessing threats to resources, using coral reefs as a model
system.
The Pacific islands have an extremely rich maritime heritage. The islands themselves were first populated by what are arguably the greatest mariners in human history. In pie-European times the Pacific islandersnavigated wooden canoes held together with coconut fibre across thousands of miles of open ocean, with
nothing but the stars and their intimate knowledge of the sea to aid navigation. Today, this seafaring tradition is continued, with several island countries, such as Kiribati and Tuvalu, being suppliers of seamento the regional and global shipping fleet.
Most of the marine protected areas (MPAs) around the world, estimated to number about 5000, have been established both on an ad hoc basis and through systematic planning processes. The
Some presentations refer to the term Marine Managed Area (MMA) instead of Marine Protected Area (MPA) in order to cover more management options. The workshop proposed and adopted a rough typology of MM As that will be useful to communicate with the key decision makers (land use planners, coastal zone planners and managers, regional planners, protected area planners and managers, community leaders, sectorial planners in fisheries and environment...)
