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 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.
This review was in preparation for Tonga's 4th national report to the CBD (Convention on Biological Diversity)

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 feasibility study was based on information gathered remotely, consultation with Tongan government agencies, community representatives and researchers familiar with the island. The authors did not visit Late and thus the recommendations presented herein do not reflect direct knowledge of the island.
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?

This dataset hosts 31 individual environmental indicator assessments that are in the **State of Environment and Conservation in the Pacific Islands : 2020 Regional report.**
Regional indicators are used to understand the current status of conservation in the region and to establish a process for periodic reviews of the status of biodiversity and implementation of environmental management measures in the Pacific islands region.
Each Pacific regional indicator is assessed with regard to:
“Vemööre” is a term in the Kwenyï language spoken by people from the Isle of Pines in New Caledonia. It is used to highlight a collective commitment and responsibility to implement the principles of life, to preserve balance, to build alliances, and to respect the word between people and between the spirits of our environment.
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.
