Funded participation in International conferences/workshops


JNCC is able to support the OTs and CDs with funding to attend international conferences and workshops.


South Atlantic regional hub


JNCC is coordinating its work in the South Atlantic  through a regional hub, based in the Falkland Islands. For more information contact the (please put OT in the subject line).


Other areas of support and advice

JNCC also provides support and advice to Overseas Territories in a number of other areas at the request of the UKOT governments. These areas include economic valuation, climate change, invasives species, accessing funding, and multilateral environmental agreements.


Blue Turtle Award

JNCC runs an annual Blue Turtle Award. People are encouraged to nominate Overseas Territories and Crown Dependencies groups or individuals who are 'making a difference'.


Trevor Glass was nominated for the 2010 Blue Turtle Award for determination, dedication and resourcefulness in achieving conservation goals on Tristan.

Training and Research Programme Steering Group


Tristan da Cunha isa member of the Training and Research Programme Steering Group which drives the direction of the OT Training and Research Programme.


Research Priorities 2011


JNCC asks the OTs and CDs for information about their top 3 research priorities each year (via members of the OT and CD Training and Research Programme Steering Group. These priorities are used to inform a number of funding decisions including the JNCC Research Contributions.




JNCC is  able to support the OTs and CDs with funding to attend environmental training courses.


In 2014 JNCC contributed to funding Norman Glass from the Tristan Government to undertake Geographical Information Systems (GIS) training in the UK.




Support to the Conservation Department



Research on the Endangered Wilkins' Bunting and restoration of woodland on Nightingale Island


In 2012 JNC made a contribution to support the work of the Conservation Department on Tristan da Cunha on the above mentioned project. More details to follow.


Invasive planning and management on Tristan and Nightingale.

in 2011, JNCC made a contribution to invasive planning and management on Tristan da Cunha and Nightingale Island.


Agreement on the Conservation of Albatrosses and Petrels

JNCC has worked with the Tristan da Cunha Government on the development of a plan for the implementation of the Agreement on the Conservation of Albatrosses and Petrels (ACAP). Tristan da Cunha ACAP plan


Invasive species project

In 2010, for the International Year of Biodiversity, the UK Department for Environment, Food and Rural Affairs (DEFRA), has funded a series of invasive species projects across the UK Overseas Territories. This has been coordinated by the Joint Nature Conservation Committee. Project activities on Tristan da Cunha were:
  • Continued control of loganberry at Sandy Point, restoration of the site (re-planting apple trees) and completion of field hut at site for ongoing work there.
  • Contribution towards the petrol costs of running the vessel which is used to access sites on Tristan da Cunha (and Nightingale and Inaccessible Islands) for ongoing work on invasive alien species.
  • Provision of training in the UK for one of the Tristan Conservation Department’s officers. Training will include invasive alien species work, monitoring, baseline data collection, and other activities associated with work on invasive alien species and climate change.
  • Continued control of priority invasive alien plant species on Tristan da Cunha and Nightingale Island. It must be noted that access to Nightingale Island is dependent on weather and sea conditions.
  • Continued work to assess the viability of using rodent bait around burrowing petrel colonies to increase the breeding success of burrow nesting seabirds at Tristan da Cunha.
  • Purchase and deploy rodent traps to strengthen contingency biosecurity plans for Nightingale and Inaccessible Islands (currently rodent-free).
  • Survey of established rodent bait stations on Inaccessible Island as part of the biosecurity surveillance plan for the island.

Non-native marine algae identification


JNCC has also funded a project which identifies non-native marine algae. This project looked at: making good collections with sequencing in mind; preparing for sequencing and inclusion in iBOL project; sending for sequencing; getting some interpretation done on the results; some 'conventional' taxonomy done on a few critical specimens.

Monitoring Seabird Populations

In 2008 the UK Department for Environment, Food and Rural Affairs provided JNCC with funding for work in the UK Overseas Territories. From this funding, JNCC made a small contribution to the Tristan Da Cunha Conservation Department for work on monitoring seabird populations.  Report  (PDF, 12 kb) on the project and images provided by Trevor Glass, Head of Tristan da Cunha Conservation Department.
