Report on the invasive species in the Caribbean, by IUCN, documenting the environmental crises and how to manage impacts on the natural island biodiversity and carrying out successful eradication.

In 2002, The Republic of Palau requested assistance from the US Department of Agriculture, Forest Service, Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of environmental concern. A comprehensive survey of the entire country was conducted and a report of the findings was submitted to the Government of Palau in 20032. This superseded a more cursory survey of the major species of environmental concern conducted in 19983. The present survey was requested as a follow-up to the 2002 survey.

The Republic of Palau requested assistance from the US Department of Agriculture, Forest Service, Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of environmental concern. A less comprehensive survey was conducted as part of a general survey of the major Micronesian islands in 19982. Similar surveys have been conducted in American Samoa, the Cook Islands, Niue, Samoa and Tonga. The survey was carried out in December 2002 and January 2003. The entire team surveyed the islands of Koror, Ngerkebesang, Malakal, Babeldaob, Angaur, Peleliu and the Rock Islands while Miles and Tiobech surveyed Sonsorol and Hatohobei States. Tiobech, Rengulbai and Terebkul Tellei surveyed Kayangel. Places of present and former habitation and those used by visitors were surveyed in the Rock Islands (Bablomekang, Betikel, Bkul a Chesemiich, Dwight Beach, Ngchelobel, Ngchus, Ngeanges (Neco), Ngercheu (Carp Resort), Ngerchong, Ngeremdiu, Ngermeyaus, Ngidech and Ulong).

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.

The Republic of Kiribati requested assistance from the US Department of Agriculture, Forest Service, Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of environmental concern. Similar surveys have been conducted in American Samoa, the Commonwealth of the Northern Mariana Islands, the Cook Islands, the Federated States of Micronesia, Niue, Palau, Samoa and Tonga. The survey was carried out in August and September 2003. We were requested to survey the islands of Tarawa, Abemama, Bern and Butaritari; however, difficulties with plane connections did not permit us to visit Bern and Maiana was substituted instead.

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 other Micronesian islands was conducted in 1998 and was discussed in a previous report2. This report summarizes a survey of the island of Rota. Commonwealth of the Northern Mariana Islands, on 5 April 2000. The objectives, as with the previous survey. were three-fold: (1) To identify plant species on the island 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 Rota, could be a threat there.

The Government of the Cook Islands requested assistance from the US Department of Agriculture, Forest Service, Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of environmental concern, similar to surveys previously conducted in Micronesia, American Samoa, Nine, Samoa and Tonga. The survey was carried out from 11 March through 1 April 2002. The islands of Rarotonga, Aitutaki, 'Atiu, Mangaia, Ma'uke and Miti'aro were surveyed. Species reported by the Cook Islands Natural Heritage Project were used for the other islands (Manuae, Manihiki, Nassau, Palmerston, Penrhyn, Pukapuka, Rakahanga, Suwarrow and Takutea) as well as for some of the uncommon cultivated species on the surveyed islands.

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 other Micronesian islands was conducted in 1998 and was discussed in a previous report". This report is based on a survey of several islands of Chuuk, Federated States of Micronesia, from 30 March to 4 April 2000. The objectives, as with the previous survey, 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 Chuuk, could be a threat there. While Chuuk has little remaining natural forest, most of these species would be a problem in secondary forests and agroforestry systems, as well.
