        Caribbean pine is a keystone species (one that is essential for the diversity and organisation of an ecological community) in the species-rich pine forest ecosystem. It is the only pine native to the Bahamas and the Turks and Caicos Islands (TCI). Caribbean pine is the national tree of the TCI where, sadly, the majority of the trees has been killed in recent years by an introduced scale insect. The TCI is one of the UK Overseas Territories.

    General Description

    Caribbean pine is a keystone species (one that is essential for the diversity and organisation of an ecological community) in the species-rich pine forest ecosystem. It is the only pine native to the Bahamas and the Turks and Caicos Islands (TCI). Caribbean pine is the national tree of the TCI where, sadly, the majority of the trees has been killed in recent years by an introduced scale insect. The TCI is one of the UK Overseas Territories.

    Species Profile
    Geography and distribution

    There are three recognised varieties of Caribbean pine, each of which has a distinct geographical distribution:

    Pinus caribaea var. bahamensis only occurs in the Bahaman archipelago, where it is found in the Bahamas (islands of Abaco, Andros, Grand Bahama and New Providence) and the Turks and Caicos Islands (TCI) (islands of Middle Caicos, North Caicos and Pine Cay). Pinus caribaea var. caribaea is found in Cuba.Pinus caribaea var. hondurensisis native to Mexico, Belize, northern Guatemala, Honduras and Nicaragua. Caribbean pine in the Bahaman archipelago

    Pinus caribaea var. bahamensis usually grows in small pockets of soil on limestone and can reach up to 25 m in height. Caribbean pine is adapted to survive natural fires that are essential for maintenance of this forest type. In the absence of fire, the undergrowth becomes overgrown and not enough light penetrates for pine seedlings to germinate. Caribbean pine provides shade, shelter and food for many other plants and animals. The Bahama parrot ( Amazona leucocephala bahamensis ) lives in these pine forests on Abaco and feeds on pine seeds. It is the only ground-nesting parrot in the Western hemisphere and the only one in the world adapted to live in an environment with frequent natural fires.


    Pinus caribaea is a tree up to 45 m tall with a single, erect trunk. It has rough, scaly, grey-brown, fire-resistant bark that breaks into squarish plates. Needles (leaves) are light or dark green, usually 15–26 cm long, and bundled into fascicles (groups) of 2 or 3 (rarely up to 5) needles. Male and female cones (reproductive structures) occur on the same tree. Pollen-bearing cones (males) are cylindrical, 2–3 cm × 5–6 mm and pink or yellow, turning yellowish or reddish-brown. Seed cones are mostly in pairs or whorls and borne on long peduncles (stalks). Female cones take two years to mature and release winged seeds that are dispersed by the wind.

    Threats and conservation

    Pinus caribaea has been listed as of Least Concern (LC) at species level according to IUCN Red List criteria, but the varieties P. caribaea var. bahamensis and P. caribaea var. caribaea have been assessed as Vulnerable (VU). Large numbers of pine trees have been killed in the Turks and Caicos Islands (TCI) in recent years due to an infestation by an accidentally introduced exotic scale insect ( Toumeyella parvicornis ).

    In response to this threat, an  ex-situ  collection, a monitoring programme and an international pine recovery working group have been established through the TCI Caicos Pine Recovery Project. A Darwin Plus project awarded in 2014 ‘Caicos pine forests: mitigation for climate change and invasive species’, with additional funds from the John Ellermann Foundation, will ensure the continuity of the project in TCI.The project hopes to conserve the Caribbean pine for the future and increase knowledge on pine ecology and species interactions. Kew’s involvement in this international collaboration is led by Martin Hamilton, coordinator of Kew’s UKOTs programme.

    Other threats to Caribbean pine include hurricanes, clearing of vegetation for new building developments and uncontrolled fires started by people. Caribbean pine has been heavily exploited as a timber tree, particularly  P. caribaea  var.  hondurensis , leading to its localised decline in some areas.

    Pinus caribaea var.  bahamensis  occurs in protected areas including the Abaco National Park on Abaco, the Lucayan National Park and Rand Nature Centre on Grand Bahama, the Blue Hole National Park and the West Side National Park on Andros, and the Conch Bar Caves National Park on Middle Caicos.

    Kew’s work on Caribbean pine in the TCI and the Bahamas

    Dr. Michele Sanchez, a member of the UKOTs team at Kew, researched the biogeography and genetics of the Caribbean pine in the Turks and Caicos Islands (TCI) and the Bahamas during her Ph.D. at Birkbeck, University of London; with help and support from other Kew colleagues and local partners Department of Environment and Maritime Affairs (DEMA) in TCI and the Bahamas National Trust in the Bahamas.

    Michele has undertaken several field trips to Caribbean pine forests to collect samples for DNA study and data on the location and ecology of the forests and to record differences among pine trees.

    Maps produced showing the size and location of modern forests and tracking changes that have occurred since the 1960s have been shared with the Bahamas Forestry Department to aid planning and management of the pine forests in the region.

    The different patterns of pollen and seed dispersal detected indicate that pines in the Bahamas and TCI forests exchanged genes in the past, but as distance between forests increased they started differentiating genetically. Considering the genetic differences observed in nuclear DNA and also the political boundaries between countries it has been suggested that these forests are managed separately and exchange of pine trees between regions is avoided if possible.

    New research by Kew staff from the UKOTs team and Jodrell Laboratory is now being carried out in the TCI pine forests as part of the Darwin Plus project, with support and collaboration of local partner, DEMA. The research includes pine genetics, mycorrhizal fungi, water relations, pine population viability studies and chemical compounds in pines and their relations to pine health and susceptibility to pests. Protocols will be established to assist local partners in managing the pine forests for the future.

    Caribbean pine is an important timber tree (particularly Pinus caribaea var. hondurensis ) and has been widely planted as such. The wood is heavily resinous and used for building, boat decks, crates, plywood and pulp manufacture. Caribbean pine trees have been widely tapped for resin in Honduras, although this use is now less common.

    Intensive logging, pulpwood and turpentine extraction and charcoal production occurred in the Bahamas during the first half of the 20th century. Wood is still extracted today for construction and boat-building but not on a commercial scale.

    Millennium Seed Bank: Saving seeds

    The Millennium Seed Bank Partnership aims to save plant life worldwide, focusing on plants under threat and those of most use in the future. Seeds are dried, packaged and stored at a sub-zero temperature in our seed bank vault.

    There are 49 collections of Pinus caribaea seed held in Kew’s Millennium Seed Bank based at Wakehurst in West Sussex.

    See Kew’s Seed Information Database for further information on Pinus caribaea seeds


    Germination trials using Caribbean pine seeds collected by partners in the Turks and Caicos Islands (TCI) and sent to Kew are currently taking place in the Quarantine House at Kew.

    After being cleaned with hydrogen peroxide (to minimise problems with damping-off fungus, which has been a problem in TCI), pine seeds were sown in a mixture of sand, perlite and Kew mix number three (a coir-based medium) and kept in a growing chamber, where they were regularly monitored. The first seedlings appeared eight days after sowing. When large enough, seedlings were potted-up and moved out of the chamber. Information obtained from this trial has been reported and shared with partners and a cultivation protocol is being written at the moment by Marcella Corcoran from the UKOTs team.

    Currently, there are 90 pine saplings growing at the Quarantine House at Kew waiting to be displayed in the gardens, used for research and shared with other institutions.
