American Samoa invasive species and action plan.
BRB

2017
American Samoa invasive species strategy and action plan for the only US territory in the South Pacific being such is faced with unique threats with its location from a national perspective and has a need for both nation al and regional collaborations. The ecological integrity of American Samoa is of utmost importance in the face of invasive species. The cultural identity of American Samoans is also closely tied to the ecological integrity of its natural environment. And given its a highly limited economy, any impact by invasive species on its natural ecosystems that provide goods and services will be almost immediate. The establishment of an invasive species plan, with its clearly articulated priority actions, goals and objectives will provide a guidance to deal with the threats of invasive species. The implementation of the plan will: (1) increase awareness of their threats; (2) inspire cooperation to prevent and minimize their impacts and implement appropriate approaches; and (3) improve decision making through the process of data and information sharing from the best available science. Priorities are: Implement urgent and necessary actions; Enhance capacities for informed decisions; Advance preventive and rapid-response protocols and measures.

Merremia peltata is a species with uncertain status in the island nations of the Pacific region. It has been designated introduced and invasive in some countries whereas it is considered native in others. Recent increase in its abundance across some island landscapes have led to calls for its designation as an invasive species of environmental concern with biological control being suggested as a control strategy. Climate change will add to the complications of managing this species since changes in climate will influence its range limits. In this study, we develop a process-oriented niche model of M. peltata using CLIMEX to investigate the impacts of climate change on its potential distribution. Information on the climatic requirements of M. peltata and its current geographic distribution were used to calibrate the model. The results indicate that under current climate, 273,132 km2 of the land area in the region is climatically unsuitable or marginal for M. peltata whereas 664,524 km2 is suitable to highly suitable. Under current climate, areas of climatic suitability for M. peltata were identified on the archipelagos of Fiji, Papua New Guinea, Solomon Islands and Vanuatu. By the end of the century, some archipelagos like Fiji, Hawaii, New Caledonia and Vanuatu will probably become more suitable while PNG and Solomon Islands become less suitable for M. peltata. The results can be used to inform biosecurity planning, management and conservation strategies on islands.
