Details of this species in Fajou Is. Status: Alien Invasiveness: Invasive Occurrence: Established Source: Lorvelec, O., et al.. 2004 Arrival Date: Introduction: Species Notes for this Location:
Management Notes for this Location: In March 2001, an attempt was made to eradicate the Javanese mangoose (Herpestes javanicus), the ship rat (Rattus rattus) and the house mouse (Mus musculus) from Fajou island in Guadeloupe. A follow up in December 2001 and January 2002 showed that the ship rat eradication had failed. There was a second attempt at eradicating the ship rats in March 2002, but it seems that it also failed. However it confirmed the success of the mongoose operation using traps alone. The success of the March 2001 house mouse operation using trapping and poisoning (Bromadiolone concentration 50 ppm, hand broadcast ) could not be properly evaluated (Lorvelec, O., et al.. 2004). Location Notes: Fajou island consists of 104 ha of mangrove on peat and 11 ha of dry vegetation on sandy soil. It is part of a natural reserve managed by the Guadeloupe National Park. Impacts: Predation: The mongose eradication, and the sharp decline in the ship rat population, ended the destruction of hawksbill turtle nests (see Eretmochelys imbricata in IUCN Red List of Threatened Species), and led to a re-colinisation of the dryer parts of the island by the clapper rail (Rallus longirostris), which had been strictly confined to the mangroves. The abundance indicies of the clapper rail and the terresrial crab Cardisoma guanhumi increased. More data is required to test the actual relationship between these increases and the reduction in alien mammal populations (Lorvelec, O., et al. 2004). Last Modified: 1/08/2006 3:54:19 p.m.
