Rapport technique du projet PROTEGE relatif à l’enquête auprès des chasseurs sur les chèvres ensauvagées à Maré

SPREP Publications, Biodiversity Conservation, BRB

Available Online

ANCB

Dans le cadre du projet PROTEGE une enquête a été réalisée à Maré par l’Agence néo-Calédonienne de la Biodiversité (ANCB) auprès des chasseurs de chèvres ensauvagées. Les objectifs sont d’évaluer les pratiques et l’effort de chasse, le niveau de prélèvements, la capacité et la volonté de diversifier les techniques de chasse et à augmenter l’effort de chasse, au regard des dégâts constatés. Les chèvres ensauvagées (ou férales, Capra hircus) contribuent à la raréfaction de nombreuses espèces végétales natives et à la dispersion et au développement de plusieurs plantes introduites envahissantes. Aux Îles Loyauté des troupeaux de chèvres sont présents sur une grande partie des corniches littorales de Lifou et de Maré, où la chasse de la chèvre ensauvagée répond principalement à un besoin pour les dons et coutumes, et pour l’autoconsommation. Une pré-enquête a été réalisée par l’animateur PROTEGE (également agent de l’ANCB), afin de recenser les chasseurs de chèvres férales sur Maré et de prendre leurs contacts pour la réalisation de l’enquête. Dans un deuxième temps, l’ensemble des chasseurs de chèvres ensauvagées identifiés ont été contactés afin de répondre à l’enquête.

Invasive alien species surveys, Aleipata Islands, Samoa : September-December 2015

Samoa is part of the Polynesia-Micronesia Biodiversity Hotspot, one of 34 regions of the world where extraordinary levels of biodiversity and endemism are coupled with extremely high levels of threat (Mittermeier et al. 2004). The four Aleipata islands (Photo 1), holding a high percentage of representative and threatened species of Samoa, certainly represent a key site in the Polynesia-Micronesia biodiversity hotspot. In a 1986 review of 226 islands in the South Pacific region, these islands together rated 30th in importance for biological diversity (Vanderwoude et al. 2006). They were also more recently included in the list of the 7 Key Biodiversity Areas of Samoa (Conservation International et al. 2010).

Bird surveys of Late and Fonualei Islands, Vava'u, Kingdom of Tonga : September 2013 - Report to Ministry of Lands, Environment, Climate Change and Natural Resources (MLECCNR)

The survey team were able to spend 3 days on Fonualei Island and two days on Late with support from a Vavau based fishing boat and checked several areas not visited during the previous 2003 and 2004 scientific surveys. We identified that the Polynesian megapode (malau) Megapodius pritchardii continues to survive in good numbers on Fonualei, locating good numbers in a new area suggesting the total population may be close to 1000. We did not located malau on Late and concluded that there is very little chance that they survive on this island. Both islands are important refuges for Tongan bird species with Fonualei Island of greater significance for malau, and seabirds which nest there in their thousands, and Late Island having a greater variety of landbirds including the endemic Samoan whistler Pachycephala jacquinoti.

Inventory of alien birds and mammals in the Wallis and Futuna archipelago

Available Online

Theuerkauf, Jorn...[et al.]

In November 2007 and November 2008, we conducted a bird and mammal survey on Wallis and Futuna. We found two non-native bird species on Wallis: the Common Myna (Acridotheres tristis) and the Chestnut-breasted Munia (Lonchura castaneothorax), and one on Futuna: the Jungle Myna (Acridotheres fuscus). We also recorded Black Rats (Rattus rattus) on Futuna, a recent introduction to this island. The introduction of 3 bird species and Black Rats in the last decade denotes a lack of preventive measures and demonstrates that the issue of invasive species has not received sufficient priority

Observations on invasive plant species in Micronesia

As requested by the Pacific Islands Committee, Council of Western State Foresters, we conducted a survey of selected Micronesian islands for invasive plant species. The objectives were three-fold: (1) To identify species on the islands that are presently causing problems: (2) to identify species that, even though they are not presently a major problem, could spread to other islands where they are not present, potentially causing problems: and (3) to look for invasive species known to cause problems in ecosystems similar to the islands visited. This report is based 011 perceptions gained from a three- week trip from July 19 to August 6, 1998, to the islands of Saipan and Tinian (Commonwealth of the Northern Marianas Islands): Peleliu, Babelthaup and Koror (Republic of Palau); Pohnpei and Yap (Federated States of Micronesia) and Guam.

Distribution, relative abundance, and habitat relationships of landbirds in the Vava'u group, Kingdom of Tonga / by David W. Steadman and Freifield, Holly B.

We assessed the distribution, relative abundance, and habitat preferences of the 12 indigenous, resident species of landbirds that survive in the Vavau Group, Kingdom of Tonga. We surveyed 16 islands, 10 of which are previously unmentioned in ornithological literature. The islands vary in land area (0.02-96 kn?), habitat composition, elevation (20- 215 m), and distance (O-lo.1 km) from the largest island of Uta Vavdu. We conducted point counts along transects on 14 of the islands, and placed each count location into one of five habitat categories. Of the 11 species of landbirds that are widespread and at least locally common, 7 (Purple-capped Fruit-Dove Ptilinopus porphyraceus, Pacific Pigeon Ducula pacijca, Common Barn-Owl Tyto alba, White-rumped Swiftlet Collocalia spodiopygia, Collared Kingfisher Halcyon chloris, Polynesian Tiiller Lalage maculosa, Polynesian Starling Aplonis tabuensis) certainly or probably occur on each of the 16 islands. One species (West Polynesian Ground-Dove Gallicolumba stairii) is extremely rare (one small population on one island). Three species that we did not record (Many-colored Fruit-Dove Ptilinopus perousii, Blue-crowned Lorikeet Vini australis, Fiji Shrikebill Clytorhynchus vitiensis) probably have been extirpated from Vavau. The species richness and relative abundance of landbirds on islands in Vavau are affected more by deforestation and other human activities than by island area, elevation, or isolation.

Observation on invasive plant species in American Samoa / by James C. Space and Tim Flynn

Space, J.C. and Flynn, T.

This is a continuation of the survey of islands in Micronesia and American Samoa for invasive plant species requested by the Pacific Islands Committee, Council of Western State Foresters. A survey of selected Micronesian islands was conducted in 1998 and was discussed in a previous report2. This report is based on perceptions gained from a trip to American Samoa from 16 to 23 July 1999, including the islands of Tutuila, Ofu, Olosega and Ta'u. The objectives were three-fold: (1) To identify plant species on the islands that are presently causing problems to natural and semi-natural ecosystems; (2) to identify species that, even though they are not presently a major problem, could spread more widely or spread to other islands where they are not present, potentially causing problems; and (3) to confirm the absence of species that are a problem elsewhere and, if introduced to American Samoa, could be a threat there.
