Report to the Republic of Palau: 2008 update on Invasive Plant Species

LaRosa, Anne Marie

Lorence, David H.

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 This superseded a more cursory survey of the major species of environmental concern conducted in 19983.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.

Samoa - Invasives prioritization and management plannning workshop, Matautu-tai, 9-10 August 2007

Conservation International/MNRE/Government of Samoa

To determine the top 20 manageable invasive plants in Samoa and to then prioritises the work that needs to be done to manage them effectively. The workshop will aim: Complete and cross check the invasive species prioritization spreadsheet for invasive plants in Samoa. Conduct prioritization to identify the top 20 priority invasive plants for active management in Samoa. Prepare an outline plan of necessary actions to manage the priority invasive species in Samoa.

The non-native vascular plants of Henderson Island, South Central Ocean

Island and Ocean Ecosystems, BRB

Waldren Steve at al.

Henderson island, a World Heritage Site in the Pitcairn group, south-central Pacific Ocean, has often been thought to have a pristine vegetation. Our archaeological investigations and field observations in 1991-1992, supported by recent observations in 1997, suggest the occurrence of former areas of Polynesian cultivation near to the North and East Beaches, and indicate that about 17 non-native vascular plant taxa have occurred. The majority of these were deliberate Polynesian introductions, some taxa are known only as sub-fossils from Polynesian occupation sites; some of this sub-fossil material may represent imported plant parts such as timber or food wraps, rather than indicating in situ cultivation. These Polynesian introductions show little spread from their probable site of introduction and are mostly restricted to the vicinity of the northern beaches; some have become extinct on Henderson. The Pitcairn islanders have also introduced a small number of vascular plants, and one of these (Passiflora maliformis) is potentially invasive. Other taxa have been accidentally introduced, at least one by a recent scientific expedition in 1991. The intact nature of much of the native vegetation may have restricted the opportunities for more widespread colonization; care is needed to ensure that this situation persists.

Report to the Republic of Palau on Invasive plant species of Environmental concern

Space, James C

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 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.

Observations on invasive plant species in Micronesia

Spaces, James C

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.

Space, James C. et al.

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.

Invasive plant species in Chuuk, Kosrae, Federated States of Micronesia

Space James C. et al.

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.
