The Falkland Islands are an archipelago made up of two main islands, East and West Falkland and about 750 smaller offshore islands and islets. They are situated in the South Atlantic to the east of Argentina, between 51oS and 53oS latitudes and 57o30’W and 61o30’W longitudes and cover an area of 12,173 km2. The average annual rainfall in the capital of Stanley is low at 635 mm and the climate is cool temperate due to oceanic conditions with average monthly temperatures ranging from 2oC in July to 9oC in January.
The first recorded sighting of the Falkland Islands was by English Captain John Davis in 1592. In 1764 the French diplomat and explorer, Louis Antoin de Bougainville, established a settlement on East Falkland at Port Louis. The following year, unaware of the French Settlement, Commodore John Byron landed at Port Egmont on West Falkland and claimed the Islands for the British Crown. Subsequently, the Spanish Government forced both French and British interests off the islands and appointed a Governor at Port Louis. After the withdrawal of both British and Spanish forces, the Islands were claimed by the newly independent Buenos Aires Government who appointed Louis Vernet Commander of the Island in 1829. Vernet was evicted and the East Falkland settlement destroyed by the US Navy after he had seized three American sealing ships; most settlers were persuaded to leave and the Americans declared the Islands free of all Government. In 1833 the British Government formally re-occupied the Islands and established a capital at Stanley in 1845.
The ongoing dispute between Argentina and the UK over sovereignty of the Islands led to their invasion by Argentine forces in April 1982. After ten weeks of war the British forces retook the Islands and the Argentinian forces surrendered on 14 June 1982.
The 2012 census gives a population of 2,932, of whom about 75% live in Stanley. Historically the economy has been based on high quality wool production, but since the mid-1980s the main source of income has been from offshore fisheries licences supported by amounts from agriculture and tourism. Oil exploration has contributed significantly to the economy over the last 5 years and the development of an oil industry is now likely.
Biodiversity
The Kew database states that 417 plant species have been found growing wild in the Falklands, of which 175 are native, including 14 endemic species. There are at least 168 species and subspecies of moss, of which 43 have not been recorded outside the Falklands, and 127 known Liverworts, including three endemic species. There are 46 species of spider of which 16 are thought to be endemic and eight introduced from Europe; 250 species of insect have been recorded including many introductions. There are only two species of native freshwater fish – the native Zebra Trout Aplochiton zebra and the Falkland Minnow Galaxius maculates. The Falkland Islands are recognised as an endemic bird area with 61 resident species, including two endemics – the Falkland Flightless Steamer Duck Trachyeres brachydactyle and Cobb’s Wren Troglodytes cobbi . The only native land mammal, the Falkland Island Fox or Warrah Dusicyon australis was persecuted to extinction by early European settlers .
Policy/Strategy background
A Falkland Islands Biodiversity strategy was published by the Government has been published for the period 2008-18 (see www.epd.gov.fk/wp-content/uploads/BiodiversityStrategy09.pdf ). This is a daughter policy to the Falkland Islands Structure Plan 2001-16. In the section on Priority Biodiversity Threats, Threat 4 covers invasive species and their potential for high impact whilst Threat 13 covers new organisms and the need for biosecurity controls. There is an action plan covering these two threats which sets out four actions. These include the development of an integrated threat assessment framework (Action 16), management provision for biosecurity at the borders (Action 17), development of a research programme on the impacts of non-native species (Action 10e) and provisions for control/eradication of invasive species (Action 18).
A South Atlantic Invasive Species Strategy and Action Plan agreed by the Governments of Ascension Island, Saint Helena, Tristan da Cunha, the Falkland Islands and South Georgia and the Sandwich Islands was published in October 2010. This set out a number of strategic aims for the South Atlantic Overseas Territories in order to develop effective prevention and response measures for invasive species and thus reduce damage to their natural heritage, communities, livelihoods and options for future development. Key actions are grouped under five objectives: (A) Building awareness and support; (B) Co-ordination, co-operation and capacity-building; (C) Prevention; (D) Monitoring, early detection and rapid response; (E) Control, management and restoration.
An invasive plants strategy is being produced by botanists from Kew Gardens. A workshop was held in late 2012 to engage with those involved with invasive plants. The strategy has is due to be completed in mid-2013. Strategies for priority invasive plants are in place and are being implemented with varying success.

Feral grazing animals
In the Falkland Islands, up until the 1980s, livestock was put seasonally onto most ground, including offshore islands. However, today due to the low prices for wool and meat, small offshore islands and some farmland areas have been fenced and de-stocked. Most livestock in the Falkland Islands are actively and responsibly managed for agriculture, with currently approximately 500,000 sheep and 6,000 cattle island-wide. There are also a small number of goats, with two flocks on two small islands, two reindeer herds and 171 pigs.

Projects
A new two-year project (Defra CR 0492), being carried out by CABI and started in January 2011, is looking at the impact of invasive non-native species in the UK Overseas Territories in the South Atlantic and the potential for biological control. Details of this project can be found at www.cabi.org/?page=1017&pid=9748&site=170.
CABI: Understanding and addressing the impact of invasive non-native species in the UK Overseas Territories in the South Atlantic: A review of the potential for biocontrol
Defra is now funding a Darwin Initiative project (Ref: 18-017 – Developing knowledge to eradicate house mice from UK OT Islands) which aims to test the feasibility of eradicating house mice from Gough Island, undertake research on the Falkland Islands and South Georgia on the impact of mice, and to create the capacity to undertake mice eradication operations on all three UK OTs. More information and projects reports can be found at http://darwin.defra.gov.uk/project/18017/.
