Torres Islands - Ecology

Ecology

Like the rest of the country, the islands are in the Vanuatu rain forests ecoregion. The coconut crab (Birgus latro) is one of its most famous species. However, since the opening of the airstrip at Linua these animals became the single most important cash crop in the Torres group. To date, the sale of Birgus has been directly governed by the fluctuating demand of the tourist market in faraway Port Vila and, to a lesser degree, the provincial township of Luganville. Predictably, the high demand for crab resulted in a gradual but incremental decline in the Birgus population across North Vanuatu, and led to a visible depletion of this creature's numbers in the Torres group. Consequently, various concerned individuals and groups successfully pressured the local provincial government of SanMa (the province in which Luganville is located) to declare a temporary ban on the sale, purchase or consumption of crab in that province. This ban first took effect in the first semestre of 2004 and is intended to be lifted sometime in early 2008. In the meantime, exports of crab from the Banks and Torres Islands (i.e. TorBa Province) to Port Vila is regulated through a relatively inefficient scheme of "open" and "closed" seasons and intra-regional quotas.
