Global Tree Seed Bank Programme
Conserving some of the world’s rarest, endangered and useful tree and shrub species as well as conducting vital tree conservation research in order to retain a significant resource for humanity.
Trees are invaluable resources, providing essential materials such as timber, fuel, food and medicines. In the landscape, they perform vital services such as water catchment, erosion and pollution control, and climate regulation. Yet, trees are under increasing threat from deforestation, over exploitation, climate change, pests and diseases. As global threats increase, we need to intensify our conservation activities in order to safeguard important species and essential resources.
Funded over a series of phases, the programme started in 2014, with the establishment of the Global Tree Seed Bank based at the Millennium Seed Bank (MSB), where the seeds of around 11,000 tree and shrub species were already conserved. From 2015 the MSB worked with partner organisations in 35 countries across the world with the aim to conserve over 3,000 of the rarest, most threatened and useful trees. In addition, research carried out at Kew and by our partners started to fill vital gaps in our knowledge of science underpinning effective tree conservation.
Following the success of the Global Tree Seed Bank Programme from 2015-2019, funding for a new phase was awarded by the Garfield Weston Foundation, to begin in January 2020 for three years. In this new phase, five of the projects represent established partnerships from the programme, allowing us to build on activities and achievements in Mexico; Madagascar; Bhutan; Thailand; and Indonesia. In addition, three new projects have been developed in Mozambique, South Africa, and Pakistan with existing Kew partners in countries with large numbers of threatened tree species, not yet banked.
Complementing the new seed collecting activity, are research projects and species conservation assessments to be carried out by in-country projects and at Kew. Based at the MSB and within the Comparative Seed Biology team, a new research project will soon begin ‘IMproving the PREservation of difficult-to-store Tree Seeds’ – IMPRETS. This research will improve our understanding of tree seed form and function and the application of low temperature science to the preservation of tree seeds.
The new programme also has a substantial training and capacity building element to strengthen partner organisations’ long-term capacity to carry out seed conservation work. This includes continuation of the MSBs Seed Conservation Techniques course and providing online training resources to a wider conservation community.
Countries and Territories Contributing to the Global Tree Seed Bank Programme
So far the Programme has received seeds from: North America (Canada, Mexico and USA); South America (Colombia); the Caribbean (The Bahamas, British Virgin Islands, Dominican Republic, Montserrat, Puerto Rico, St Lucia and the Turks and Caicos Islands); Africa (Cameroon, Guinea, Nigeria, Sierra Leone and Madagascar); Europe (Austria, Belgium, Cyprus, Finland, Italy, Poland, and Spain) and the Caucasus (Azerbaijan, Armenia and Georgia); Asia (Bhutan, Indonesia, Japan, Taiwan, and Thailand); Australia and the Pacific (Hawaii, Fiji, New Zealand and Papua New Guinea). With so many regions involved, there are over 50 participating partners.
The main objectives of the programme are to:
1. Collect, bank and conserve up to 5000 of the world’s rarest, most endangered and most useful tree and shrub species
Improve knowledge of the seed biology, germination, and propagation of key species
2. Address key knowledge gaps in tree conservation with research in major areas of tree conservation:
Development of generic protocols for banking recalcitrant (desiccation sensitive) seeds;
Analysing the functional seed traits of palms, in order to improve collection strategy and storage protocols;
Improve our knowledge of palm species relationships and evolution, with particular focus on the Indo-Pacific tribe Areceae;
Compiling DNA sequence data for all genera of South East Asian trees to explore links between conservation and evolution;
In the new phase of the programme:
Improve our understanding of tree seed form and function and the application of low temperature science to the preservation of tree seeds.
3. Invest in training, essential infrastructure, equipment and data sharing to increase our partner organisations’ long-term capacity to carry out seed conservation work.
This is a large programme involving 38 countries and with over 50 partners and collaborators. More information on partners can be found in the individual project webpages.
By December 2019:
Seeds from 3863 tree and shrub species from 35 countries have been conserved
In the Comparative Plant and Fungal Biology Department at Kew, four research fellowship projects have been completed and research published, or in process of submission.
More than 340 people have been trained in Seed Conservation Techniques either in country or at the MSB.
15 Blue Drum kits (mini seed banks) have been sent to partners in Africa, Asia, the Caribbean and the Pacific
A new seed bank was established in the National Botanical Garden of Santo Domingo, Dominican Republic (Feb 2017). Two small national seed banks were also set up in 2017 at the IRAD-National Herbarium of Cameroon and at UGAN-C-National Herbarium of Guinea. In Azerbaijan, during the project a permanent and purpose-built Seed Bank Department was established, based at the Institute of Botany.
Research projects have been completed by partners in Colombia, the Dominican Republic, Georgia, Italy, Japan, Mexico and New Zealand.
A critical checklist of the woody flora of Tuscany has been published and the project contributed to field work for a tree guide for Georgia (not yet published).
