Pitkern Botanical Garden

Safeguarding native plants for future generations

Background

Pitcairn Island, the only inhabited island in the remote Pitcairn Islands group in the South Pacific, is home to a unique and fragile ecosystem. Despite its small size and isolation, Pitcairn supports a range of native and endemic plant species, many of which are found nowhere else in the world. The island’s rugged terrain, volcanic soils, and subtropical climate have shaped a distinct flora that reflects both its Pacific heritage and its evolutionary isolation. 

The native vegetation has been significantly impacted by historical land use, introduced species, and environmental change, making conservation efforts increasingly vital. Protecting Pitcairn’s native flora not only preserves biodiversity but also supports cultural identity, ecosystem resilience, and long-term sustainability for the island’s small community.

About

The Pitkern Botanic Garden (PBG) exists to value, safeguard, study, and celebrate the unique plant biodiversity of Pitcairn Islands. Protecting these rare species from invasive plants and animals is essential to preserve biodiversity and ecosystem health. Effective conservation requires targeted control of invasive species, habitat restoration, and ongoing monitoring. Equally important is ensuring that accurate data, scientific research, and local ecological knowledge are collected and shared. 

The living and preserved plant collections are central to our mission of conservation, education, and research. By developing education and community engagement, we can build long-term stewardship and inspire sustainable management. Together, these efforts safeguard the Pitcairn Islands’ native plants for future generations and maintain their irreplaceable ecological legacy.

The project aims to conserve native and endemic plant species through propagation, habitat restoration, and invasive species management, contributing to biodiversity protection. It will serve as a hub for environmental education, community engagement, and cultural preservation by showcasing plants of ecological and traditional significance. The project builds local capacity through hands-on training in horticulture and sustainable land management, while also supporting research and citizen science. As a nature-based solution, the garden will create a greener, more resilient landscape that benefits biodiversity, climate adaptation, and community well-being.

Budget

The project is seeking funding to develop the develop the garden. A provisional budget is set at between £50,000-250,000. 

Contributions towards International Targets

Global Biodiversity Framework Targets

The UN Convention on Biological Diversity (CBD) sets global goals to protect biodiversity through its targets, most recently updated as the Kunming-Montreal Global Biodiversity Framework in 2022. These targets aim to halt biodiversity loss by 2030 and include goals such as protecting 30% of land and sea areas, restoring 30% of degraded ecosystems, reducing pollution, and ensuring sustainable use of natural resources.

Sustainable Development Goals

The UN Sustainable Development Goals (SDGs) are a set of 17 global goals adopted by the United Nations in 2015 to end poverty, protect the planet, and ensure prosperity for all by 2030. They cover a wide range of issues, including health, education, gender equality, clean water, climate action, and biodiversity. Each goal has specific targets and indicators to measure progress, encouraging countries to work together toward a more sustainable and equitable future.

Partners

The project will be run by the Pitkairn community in collaboration with a number of partners including UKOTCF.
