In June/July 2002 an eradication programme to remove Pacific rats from Maninita Island in the Vava'u group of the Kingdom of Tonga was initiated. The techniques used were similar to those
used in successful rat eradications in New Zealand, in that Pestoff 20R pellets and a network of bait stations were used.
Conditions on the island were not what was expected, the forest having been adversely affected by cyclone Waka and subsequent defoliation by caterpillars, resulting in an open forest canopy. Rats were found to be present on the island in high numbers and were breeding.
Work is based around country visits by the network coordinator to support PILN teams to identify and take strategic action to manage their priority invasive species. The network is functioning by sharing awareness of successful activities being earned out by the teams, providing the mechanism for other teams to do the same, and actively encouraging them to do so.
Capacity building is linked to on-going invasive species projects and achieved through workshops and exchanges.

Williamson and Sabath (1982) have demonstrated a significant relationship between modern population size and environment by examining atoll area and rainfall in the Marshall Islands. The present work seeks to extend that argument into prehistory by examining the relationship of ancient habitation sites and size of aroid pit agricultural systems to atoll land area and rainfall regime along the 1,500-3,500 mm precipitation gradient in the Marshall Islands.
This document is a review of the status, trends and threats to Tonga’s unique biodiversity since the inception of its own NBSAP in 2006. The review also covers the status of the implementation of objectives and action plans, sectors and cross sector collaboration.

One of the recommendations emerging from the COP-8 (Decision XIII/8 [6]) promoted a series of regional and/or sub-regional workshops on capacity building for NBSAPs. These will
be held with the aim to discuss national experiences in implementing NBSAPs, the integration of biodiversity concerns into relevant sectors, obstacles, and ways and means
for overcoming these obstacles. It was recommended that these workshops be held (subject to the availability of funding) prior to COP-9, to provide an opportunity to directly support
Natural capital our ecosystems, biodiversity, and natural resources underpins economies, societies and individual well-being. The values of its myriad benefits are, however, often overlooked or poorly understood. They are rarely taken fully into account through economic signals in markets, or in day to day decisions by business and citizens, nor indeed reflected adequately in the accounts of society.

Avariety of factors can affect the biodiversity of tropicalmammal communities,
but their relative importance and directionality remain uncertain. Previous
global investigations of mammal functional diversity have relied on range
maps instead of observational data to determine community composition. We
test the effects of species pools, habitat heterogeneity, primary productivity
and human disturbance on the functional diversity (dispersion and richness)
of mammal communities using the largest standardized tropical forest camera
This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or
extrapolations based on experiments and observed trends. The term biodiversity is used in a broad
sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions
of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis
pays particular attention to the interactions between biodiversity and ecosystem services and to
The research agreement signed on 19th December 2005 by the Institute of Research for Development (IRD), the University Paul Sabatier (Toulouse III) and Nantes University, the Pharmacochemical laboratories of Natural Substances and Pharmacophores Redox (UMR 1165) and the Centre of Maritime and Ocean Law (EA 1165, CDMO) led to the international research program Coral Reef Initiatives for the Pacific (CRISP).
Late is an isolated and uninhabited island located about 55 km WSW of the island of Vava’u, in the Kingdom of Tonga. The biological integrity of Late is threatened by invasive Pacific rats that were historically introduced to the island. This report assesses the feasibility of restoring Late through the removal of invasive rats, and describes options, recommendations, and challenges to realizing a successful project.
This is about conservation in Tonga.
The Tonga State of the Environment 2018 report has been developed to answer three key questions related
to the environment of Tonga, and is based on seven thematic areas:
• What is the current condition of the Tongan environment?
• What are the risks the Tongan environment faces and what measures have been put forward to minimise them? This could provide lessons for Tonga.
• Where is the environment of Tonga headed based on the assessed thematic areas?
The World Database on Protected Areas (WDPA) is the most comprehensive global database of marine and terrestrial protected areas, updated on a monthly basis, and is one of the key global biodiversity data sets being widely used by scientists, businesses, governments, International secretariats and others to inform planning, policy decisions and management.
This dataset contains preliminary impact assessments of the Hunga-Tonga-Hunga-Ha'apai volcanic eruption and induced tsunami in January 2022.
The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down. The eruption was likely the biggest recorded anywhere on the planet in more than 30 years, according to experts.
