Pacific Island Ecosystems at Risk project (PIER) reports
"Report to the Government of Niue on Invasive Plant Species of Environmental Concern"
The Government of Niue 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 and American Samoa. The survey was carried out from 15-19 May 2000. 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 Niue, could be a threat there; and (4) make appropriate recommendations.

Invasive plant species on Kosrae, Federated States of Micronesia
This is a continuation of the survey of islands in Micronesia 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 the island of Kosrae, Federated States of Micronesia, from 24 to 28 March 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 Kosrae, could be a threat there. (report by James C Space, Barbara Waterhouse, Julie S. Denslow, Duane Nelson and Erick E. Waguk)
"Invasive Plant Species on Rota, Commonwealth of the Northern Mariana 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 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. (report by James C. Space, Barbara Waterhouse, Julie S. Denslow and Duane Nelson)
"Invasive plant species in Chuuk, Federated States of Micronesia"
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. (report by James C Space, Barbara Waterhouse, Julie S. Denslow, Duane Nelson and
and Thomas R. Mazawa)
"Observations on invasive plant species in Micronesia"
This report is based on 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 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. (report by James C. Space & Marjorie Falanruw)
"Observations on invasive plant species in American Samoa"
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. (report by James C. Space & Tim Flynn)
