Invasive species in the Pacific: a technical review and draft regional strategy
Referred to simply as "the SPREP report" by many who know it, this document was published by the (External)
South Pacific Regional Environment Programme (SPREP)
in June 2000 with funding assistance from the Government of Australia.
Its foreword states:
"The publication contains a series of technical reviews of land and freshwater invasive species, non-technical summary of the same together with an account of legislation about invasive species, and the pathways by which these species gain access to countries. Also included is a draft regional strategy for invasive species."

Turning the tide: the eradication of invasive species
(Veitch & Clout [eds.]/IUCN-SSC-ISSG 2002)
"The papers and abstracts published in this book are the outcome of the International Conference on Eradication of Island Invasives held at the University of Auckland, 19 to 23 February 2001.
This conference sought to focus on the subject of: 'Eradication of invasive species from islands; methods used and the results achieved.'"

Phenology, reproductive potential, seed dispersal and predation, and seedling establishment of three invasive plant species in a Hawaiian rain forest.
(Medeiros, A.C. 2004. Ph.D. dissertation, Department of Zoology, University of Hawaii at Manoa, Honolulu.)
[New!]
After rain forest of Haleakala National Park was fenced in the late 1980s, native vegetation responded vigorously yet three problematic plant invaders (
Clidemia hirta
,
Hedychium gardnerianum
, and
Psidium cattleianum
) continued to spread unabated and became of great concern to Park managers. This contribution provides a quantitative assessment of crucial life history junctures (quantitative phenology, reproductive potential, seed dispersal, seed predation, seedling establishment) to assist Haleakala NP and other managers of Hawaiian rain forests. It also provides detailed information for potentially identifying key characteristics in prevention, rapid response, and prioritization of incoming invasive species.

Kahului Airport Pest Risk Assessment ("KARA report")
(HDOA 2002)
"By conducting seven, three- to four-week inspection blitzes between September 2000 and July 2001,the Plant Quarantine Branch of the Hawaii Department of Agriculture performed a risk assessment on the movement of alien species from the continental United States and foreign areas to the Island of Maui through Kahului Airport. The Kahului Airport Pest Risk Assessment (KARA) involved intensive inspections of checked and carry-on-baggage by inspectors and detector dog teams; inspections of aircraft cabins and cargo holds of mainland flights; and 100% inspections of agricultural products shipped by air cargo."

Filling the gaps in the fight against invasive species
This study was prepared in response to Hawaii State Senate Concurrent Resolution No. 45, H.D. 1 (2001), which directed the Legislative Reference Bureau to conduct a study on policy recommendations and funding options for a comprehensive alien invasive species protection and control program for the State of Hawaii.
The introduction to the report says, in part:
"The Legislature recognized the environmental and economic threat posed by invasive species and was well aware of the efforts to address this problem by federal, state, county and concerned private organizations. The Legislature, however, was also aware of state invasive species programs that were 'piecemeal [and lacked] adequate rigor, comprehensiveness, and political will ....' To resolve this administrative problem, the Legislature adopted Senate Concurrent Resolution No. 45 in an attempt to provide policy recommendations and funding options to develop a comprehensive invasive species protection and control program for the State of Hawaii.

GAO Invasive Species Report
In October 2002, the United States General Accounting Office (GAO) produced a "Report to Executive Agency Officials" entitled
(External)
Invasive Species:
Clearer Focus and Greater Commitment Needed to Effectively Manage the Problem."
An overview of the document's contents is presented here as a compilation of edited excerpts from the introductory text of the document:
Harmful invasive species--nonnative plants and animals that are spreading throughout the United States--have caused billions of dollars in damage to natural areas, businesses, and consumers. In 2001, the federal government issued a National Invasive Species Management Plan to focus attention on invasive species and coordinate a national control effort involving the 20 or so federal agencies that are responsible for managing them. This report discusses the economic impacts of invasive species, implementation of the management plan, and coordination of U.S. and Canadian efforts to control invasive species.
Existing literature on the economic impacts of invasive species is of limited usefulness to decision makers, although it indicates that the effects of invasive species are significant. Most economic estimates do not consider all of the relevant effects of nonnative species or the future risks that they pose. New initiatives may prompt more comprehensive analysis that could help decision makers make better resource allocations.
While the National Invasive Species Management Plan calls for many actions that are likely to contribute to preventing and controlling invasive species in the United States, it does not clearly articulate specific long-term goals toward which the government should strive. In addition, the federal government has made little progress in implementing the actions called for by the plan.
GAO recommends that the National Invasive Species Council (1) incorporate data on the economic impacts of invasive species in developing the federal government's budget; (2) add performance-oriented goals and objectives to its updated plan; (3) give high priority to an oversight strategy for measuring progress against results-oriented goals; and (4) examine whether the council is being hampered in its implementation of the plan by the lack of specific legislation.
Agencies generally agreed with GAO's recommendations.

Guilty Until Proven Innocent: Preventing Nonnative Species Invasions
This article from "Conservation in Practice" (Winter 2001 Vol. 2, No. 1) discusses using what's been called the "precautionary principle"--whereby species are considered "guilty" of being potentially invasive until proven "innocent" (non-invasive)--to prevent non-native species invasions.

Prioritizing Weeds: The Alien Plant Ranking System
This article from "Conservation in Practice" (Winter 2001 Vol. 2, No. 1) discusses an alien plant ranking system (APRS), an automated web-based resource that can help managers work through tough decisions about prioritizing the management of alien plants.
APRS helps identify those species that have the most serious impact-those on site of limited distribution or off site with a high potential to invade, as well as those that appear innocuous (usually the majority). APRS also helps managers assess the feasibility of controlling the most threatening species.

The Workshop on Databases for Nonindigenous Plants brought together a unique group interested in documenting, tracking, and monitoring the spread of nonindigenous plants. The workshop focused on developing a clearer picture of how databases are being or could be used to document the range and spread of nonindigenous plant populations across the nation. Additionally, it highlighted the importance of needed interagency tools for exchanging information and how information exchange might improve the ability to better document and track these species. By providing a forum to present and discuss databases, an initial step was taken in improving recognition and communication among data managers. The workshop also resulted in a survey and inventory of databases to be used as a resource for administrators and data managers.

Weed Risk Assessment and Prevention in Hawaii: Status and Practicalities
Few efforts at weed risk assessment in Hawaii have been undertaken; several of those efforts are described here,
and their degrees of success discussed. A number of federal, state, private, and multi-agency organizations have
interests in the negative effects of alien species invasions in Hawaii, and may benefit from better weed risk
assessment protocols. Weed risk assessment is discussed with respect to its applicability in Hawaii. Economic,
political, and other practical aspects of alien species problems are addressed. Finally, issues are addressed
which are deemed necessary to progress in the battle against problems caused by invasive alien species in
Hawaii.

Using pathway analysis to inform prevention strategies for alien reptiles and amphibians
PDF icon
[New!]
"Alien reptiles and amphibians are deserving of greater attention that has hitherto been bestowed upon them by managers and researchers. Eradication or control of established taxa will generally be infeasible, leaving prevention of introductions as the primary management tool for controlling herpetological
invasions....
Because of variation in pathway importance, information on how taxonomic, temporal, and geographic variables co-vary with economic and social data may allow for predictive assessment of pathway risk for accidental introductions. In contrast, some predictive assessment of taxon risk was achieved using variables that measure climate-matching between native and introduced ranges, phylogenetic risk, and prior history of successful taxon establishment."

"Report to the Government of Niue on Invasive Plant Species of Environmental Concern"
PDF icon
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
PDF icon
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.

"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.

"Invasive plant species in Chuuk, Federated States of Micronesia"
PDF icon
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.

"Observations on invasive plant species in Micronesia"
PDF icon
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.

"Observations on invasive plant species in American Samoa"
PDF icon
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.
