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).

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.

The Kingdom of Tonga 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 and Niue. The survey was carried out from 5-20 July 2001. The islands of Tongatapu. ‘Eua, Vava'u, Ha'ano, Lifiika, Foa and ‘Uilia were surveyed. The latter four islands are in the Ha'apai group of islands. The survey of Ha'ano was not as thorough as we would have liked because stormy weather forced us to return to Lifnka. The objectives, as with previous surveys, were to: (1) identify plant species that are presently causing problems to natural and semi-natural ecosystems; (2) identify species that, even though they are not presently a major problem, could spread more widely or are known to be problem species elsewhere: (3) confirm the absence of species that are a problem elsewhere and if introduced to Tonga, could be a threat there: and (4) make appropriate recommendations.

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.

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.

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 objectives of the survey were to: (1) identify plant species presently causing problems to natural and semi-natural ecosystems; (2) identify species that, even though they are not presently a major problem, could spread more widely or are known to be problem species elsewhere; (3) confirm the absence of species that are a problem elsewhere and, if introduced to Samoa, could be a threat there; and (4) make appropriate recommendations.
