Invasive Plants

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

As our global economy grows and the boundaries between nations shrink, we face new social, environmental, and economic challenges.

The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017. The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size, global reach and of course financial cost. In the space of a few decades, the size of islands treated for invasive species has increased by five orders of magnitude – from a few hectares to over 100,000 ha or 1,000 km2.

Invasive weeds are one of the most serious threats to biodiversity and sustainable development in the Pacific region. Biocontrol is likely to be the only feasible way of managing many widespread weeds, but is not always appropriate or successful. With so many weed species to tackle and inevitably limited resources, prioritising where to direct control efforts most effectively is of key importance. Landcare Research recently developed a framework for the Australian government that allows the best and worst weed targets for biocontrol to be identified.

Native plants and animals can rapidly become superabundant and dominate ecosystems, leading to claims that native species are no less likely than alien species to cause environmental damage.

This paper is a report on a collection of plants made during an 11-month stay in Samoa, from August to November 1929, and from June 1931 to January 1932, and on other Samoan collections of plants in Bernice.

Journal of Coastal Research, SI No. 21, pp. 111-144. Fort Lauderdale (Florida), ISSN 0749-0208. The effects of Hurrican Andrew upn the forests of south Florida as of early 1994 are summarized from studies conducted at sites located within the track of the storm as it passed across the peninsula. Updated information on the storm's track and eyewall configuration also is provided.
