2017 Biosecurity and invasive species workshop to protect Tokelau

Apia, 1 December 2017

A successful workshop on biosecurity and invasive species for Tokelau was held in the last week of September, in the offices of the Tokelau National Public Service in Apia. Participants came from all three Tokelau atolls – Atafu, Nukunonu and Fakaofo – and from the Tokelau Apia Liaison Office. The course was led by Dr Monica Gruber of Victoria University in Wellington. She was supported in this by David Moverley, David Sakoda and Bradley Meyer of the Pacific Regional Environment Programme (SPREP) in Apia, and by Lesio Saurara of the Pacific Community (SPC) in Suva. Tokelau legal adviser Lise Suveinakama also chipped in.

Tokelau trainees use microscopes to identify invasive ants. Each village rep took a donated microscope home with them.
During the 5-day workshop, participants were trained in various aspects of biosecurity. The aim was to define a sustainable system for reducing biosecurity risks posed by bringing plant disease and invasive species into Tokelau. Staff of the Department of Economic Development, Natural Resources & Environment (EDNRE) had a particular role to play here. For example, they familiarised themselves with the Biosecurity Rules of Tokelau.
For EDNRE on-all three atolls, the recognition, monitoring and control of invasives such as fruit fly, coconut rhinoceros beetle, mealybugs and whitefly is important, as is the control of Pacific rats. Of particular concern in recent years was were the yellow crazy ant, for the control of which a special Pacific Invasive Ant Toolkit (PIAT) has been developed on the Internet, with the assistance of EDNRE staff and the village of Atafu.

On the vegetation side of things, management of weeds was highlighted as a priority. The Singapore daisy (or Wedelia) is a particularly persistent plant species that, although pretty, can get in the way of many things. Participants were shown how to use a weed sprayer to good effect, without causing further environmental problems. How to keep solar panels free from infestations was also an important review, given that the villages on the atolls derive almost all their electric power from solar energy.

The week-long workshop was funded by the New Zealand Ministry of Foreign Affairs and Trade through the NZ Aid Programme Activity “Building resilience to biosecurity threats from invasive ants throughout the Pacific”, of which Tokelau is a partner.
