Tokelau Invasive Species Strategy and Action Plan (TISSAP) 2020 -2027

Island and Ocean Ecosystems, BRB

Available Online

Government of Tokelau

The TISSAP addresses existing IS in Tokelau, via prioritization and guidance. It addresses the potential invasion pathways of additional IS to Tokelau through foreign and domestic vessels that could provide opportunities for other weeds, rats, mongoose, invertebrates and diseases that could have catastrophic impacts on biodiversity, economic growth, community and heath

Island and Ocean Ecosystems, BRB

We are a central Pacific nation comprising three atolls lying to the north of Samoa and south of the Phoenix Islands of Kiribati, and centred on latitude 9o S. The areas of the atolls are roughly similar – Atafu c.350 ha, Nukunonu c.500 ha and Fakaofo c.400 ha – and each gaining only a few meters elevation. All three islands are classic atolls being at the summit of ancient, raised seamounts projecting upward about 5000 m from the seabed, and with large open lagoons which have shallow passages to the sea in many places. The climate is moderated by the ocean currents and easterly trade winds that blow steadily throughout the year and the wet season occurs in November-April. Cyclones and storm surges sometimes inundate much of the land as occurred at Fakaofo in the early 2000s.

Secretariat of the Pacific Regional Environment Programme.

In 2014, with support from the French Government, Wallis and Futuna informed SPREP of its intention to identify nationally significant wetlands for future designation as wetlands of international importance (Ramsar Sites) under the Convention on Wetlands (Ramsar, Iran, 1971).

Implementation plan 2017-2022. Government of Tokelau.

The Implementation Plan, is the companion document to the Living with Change: An integrated national strategy for enhancing the resilience of Tokelau to climate change and related hazards, 2017-2030 (LivC). It provides an overview of how implementation of LivC will occur during the first five years.

The status of weed biological control in Vanuatu

Available Online

Bule, Sylverio

Day, Michael D.

Biological control of weeds in Vanuatu began in 1935, with the introduction of the tinged Teleonemia scrupulosa to control Lantana camara. To date, nine biological control agents have been intentionally introduced to control eight weed species. Seven of these agents have established on their respective hosts while an eighth, Zygogramma bicolorata, an agent for Parthenium hysterophorus has only recently been released and establishment is unlikely.

Potential impact of climate change on the distribution of six invasive alien plants in Nepal.

Shrestha Uttam Babu

The biological invasions have been increasing at multiple spatial scales and the management of invasive alien species is becoming more challenging due to confounding effects of climate change on the distribution of those species. Identification of climatically suitable areas for invasive alien species and their range under future climate change scenarios areessentialfor long-term management planningofthesespecies. Using occurrence data of six of the most problematic invasive alien plants (IAPs) of Nepal (Ageratum houstonianum Mill., Chromolaenaodorata (L.) R.M. King & H. Rob., Hyptis suaveolens (L.) Poit., Lantana camara L., Mikania micrantha Kunth, and Parthenium hysterophorus L.), we have predicted their climatically suitable areas across the country under the current and two future climate change scenarios (RCP 4.5 scenarios for 2050 and 2070). We have developed an ensemble of eight different species distribution modelling approaches to predict the location of climatically suitable areas. Under the current climatic condition, P. hysterophorus had the highest suitable area (18% of the total countrys area) while it was the lowest for M. micrantha (12%). A predicted increase in the currently suitable areas ranges from 3% (M. micrantha) to 70% (A. houstonianum) with the mean value for all six species being 29% under the future climate change scenario for 2050. For four species (A. houstonianum, C. odorata, H.suaveolens and L. camara), additional areas at elevations higher than the current distribution will provide suitable habitat under the projected future climate. In conclusion, all six IAPs assessed are likely to invade additional areas in future due to climate change and these scenarios need to be considered while planning for IAPs management as well as climate change adaptation.

Report on results of rat control trials in the Tokelau Islands from 30 July to 20 September 1970 and recommendations for a comprehensive scheme of rat control

Available Online

Kazimierz Wodzicki

The visit to the Tokelau Islands described below is the third carried out in a study of ecology, rat control and related problems. The first visit in 1966/67 (Wodzicki 1968 A) was devoted primarily to the study of the ecology of the Polynesian rat (Rattus exulans) and the environment, including the animals and the vegetation, of Nukunonu atoll. The main objects of the second expedition in April-June 1968 (Wodzicki 1968 B) were the initiation of a long-term investigation of rat damage on all three atolls and the training of two men from each island as rat control operatives. The present visit was planned with the following tow main objectives in mind: 1. the study of the relationship of rat damage to various coconut varieties growing in the Tokelau Islands; and 2. the conduct of rat control trials with the view of preparing for the Administrator, Tokelau Islands (Mr. Richard B. Taylor) recommendations for a rat control scheme suitable for the Tokelau Islands. The preliminary analysis of data collected during the fifteen months long investigation of rat damage in 1968/69 on the three atolls suggested that palms belonging to some varieties may be more prone to rat damage then others (Wodzicki 1970). It seemed important that we learn more about the character of palms growing on the three atolls. With regard to rat control, trials with various kinds of poisons have been carried out since our first visit to the Tokelaus in 1966/67 (Wodzicki 1968 A). However, during our first two visits knowledge of rat ecology was not sufficiently advanced to allow for more sophisticated tests. Since the author's 1968 visit, the important work on rat control in the Gilbert and Ellice Islands by F.J. Smith (Smith 1969) has become available. This information and our knowledge of rat ecology, gradually acquired since the beginning of the Tokelau Islands rat project, now makes possible a programme that could become the basis of a practical rat control scheme for the three islands. As most of the previous work had been carried out on Nukunonu atoll only, it was felt that half of the time during the visit should be spent on Fakaofo and th remainder on Atafu. Following a brief descrption of these trials is the writer's recommendation of a rat control scheme submitted to the Administrator, Tokelau Islands. Finally, some other observations on plants, animals and related aspects are friefly reported and collections made for the Botany Division, D.S.I.R. and the Dominion Museum are briefly mentioned.
