Context
Regional economic development trend
• Stable for FKL & ASI, variable for STH & TDC
• Population: Low, <8,500 people across all 4 territories
Environmental trends
• Highly impacted by invasive species (~934 species) and climatic change
Challenges faced
• Remote areas which are difficult and expensive to access
• Often lack of understanding about the region from outside organisations
and bodies

Biological importance of the region
• Four highly diverse island ecosystems
spanning the South Atlantic ocean
• Range from cool-temperate to warm-tropical
systems

Biological importance of the region
St Helena marine inshore ecosystem – Local
community reliant on it for:
• Food: ~62,000kg/year consumed
• Tourism: developing for whale sharks and
humpback whales
• Fisheries export: 2011/12 = 643,000kg exported;
2013/14 = 0kg exported

Falkland Islands – Squid species
• 2 species, Illex argentinus and Loligo gahi (left)
• Licenses sold to harvest these species
generate £10-30 million per annum

Existing biodiversity
• Total of 780 species to date = >50%
of all UK OT endemics

Existing biodiversity
• Value of natural environment recognised across the region
• Almost all economies reliant on environmental resources
• Majority of territories terrestrial areas have some protection
 52% (excluding FKL)
• Lack of marine environment baseline data and funding 
generally low levels of protection and management

Threats and pressures on biodiversity
Some common threats between all regional territories:
- Climate change
- Invasive Alien Species (~934 sp.)
- Illegal fishing
- Biosecurity
- Resource management
Some threats being tackled are territory specific:
- Falkland Islands developing offshore oil and gas industry
- St Helena’s new airport development
However, there are NO long
term financial management
plans in place to deal with
these threats

• House mice feed on the endemic Tristan Albatross [CR]
• Identified by the RSPB as the top priority for action
Ascension Island:

Local governments are invested
in environmental work BUT
majority of staff externally funded
Only 50% of the territories have

Current investments in conservation
St Helena: Securing St Helena’s rare cloud forest flora & invertebrates
• Relevance: <1km2 supports 119 endemic plant and
invertebrate species that aren’t found anywhere else on the
island
• Problem: Risk to be completely lost in the next 5 years
• Aim/solution: Restore keystone endemic tree
species and create seed collections
• Investment: >£630,000
external funds currently
invested in multiple
ongoing projects

Critical areas for action & investment needs
Invasive species control & Biosecurity
© Phil Lambdon

•
Invasive species: New Zealand flax (STH), the
European earwig (FKL) and rodents (ALL)
•
Highly sensitive and vulnerable endemic species:
He Cabbage tree (STH), Cobb’s wren (FKL),
Tristan Albatross (TDC)
•
Without adequate investment could result in
widespread loss of species
Climate change impact assessments
• Climate change impacts relatively unknown for
most the region
• Island systems highly susceptible to effects,
like sea level rise
• Lack of current funding throughout the region

Priorities & investment niches
BASELINE DATA COLLECTION
Need to know what you have before you can protect it
Invasive species eradication
Inevitable loss of species in the next 5 years if no action is taken
Understanding impacts of a
changing climate
Currently few studies, unknown how the majority of endemics will
respond
South Atlantic Hub
Priorities & investment niches
Surveying of habitats, especially marine
environment, to better inform action and
management plans
Eradication/control of invasive plants and
small mammals crucial on all islands
Appropriate and enforced biosecurity
measures
Terrestrial habitat restoration
