The potential detrimental impact of the New Zealand flatworm to Scottish islands

Boag, B.

Neilson, R.

The New Zealand ?atworm, Arthurdendyus triangulatus, is an alien invasive species in The British Isles and the Faroes. It was probably ?rst introduced after WWII and is an obligate predator of our native earthworms. It was initially considered a curiosity until observations in the 1990s in Northern Ireland found it could signi?cantly reduce earthworm numbers. In 1992, it was scheduled under the Countryside and Wildlife Act 1981 then transferred to the Wildlife and Natural Environment (Scotland) Act in 2011 which makes it an o?ence to knowingly distribute the ?atworm. A retrospective survey in Scotland showed that it was detected in botanic gardens, nurseries and garden centres in the 1960s but then spread to domestic gardens then ?nally to farms in the 1990s. Although the geographical distribution of A. triangulatus was initially con?ned to mainland Scotland it was subsequently found established on 30 Scottish Islands. Most of the islands are to the north and west of Scotland and have cool damp climates which are favoured by the New Zealand ?atworm. These islands also generally have relatively poor soils that support grassland farming systems. Evidence from both Northern Ireland and Scotland suggests anecic species of earthworm which occur predominantly in grassland, which help drainage and are a source of food for both animals and birds are at particular risk from the ?atworm. The detrimental impact of the ?atworm on soil processes and wildlife has yet to be quantitatively evaluated but unlike many other invasive species there is currently no known means of control. The precautionary principle must be therefore applied wherever possible and every opportunity taken to stop its further spread.

This island nation contains many marine eco-systems, from globally significant coral reefs to mangroves, seagrass areas, seamounts and deep-sea trenches supporting at least 769 fish species, including sharks and rays, as well as whales, dolphins and sea turtles.

Alien versus native species as drivers of recent extinctions.

Bellard, C

Blackburn, T M

Ricciardi, A

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.

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. Meanwhile, the diversity of species being tackled has increased, as has the range of countries now actively carrying out island restoration work. Inspired by pioneers from New Zealand and Australia, principally, today the movement has spread to islands in all oceans and off all continents. This expansion has been informed by, and has in turn produced, growing experience in all aspects of this field, from non-target impacts to ecological responses to factors affecting eradication success. A major aim of publishing these Proceedings is to inform people who are, or will in the future be, planning new projects to free islands of invasive species. Regardless of its location or the target species involved, each successive operation builds on the experience of those who have gone before, and the papers in this volume represent an invaluable wealth of such experience.
