Global Tree Seed Bank: Unlocked

Working with the Royal Botanic Gardens, Kew

Language:

The Global Tree Seed Bank Programme is securing some of our planet's most threatened, rare and useful tree species. Funded by the Garfield Weston Foundation and coordinated by the Royal Botanic Gardens, Kew (RGB, Kew), the programme aims to collect and store seeds of more than 5,000 of the world's tree species.  In Thailand, under the third phase of the project, FORRU-CMU worked in partnership with the Bangkok Forestry Herbarium (BKF) to collect and conserve seeds of 300 native species.

Together with BKF, we also produced conservation assessments and distribution maps of 225 of Thailand's endemic tree species for IUCN's Red List system, with support from RBG Kew’s Plant Assessment Unit (PAU). Full details of FORRU-CMU's contribution to this project can be read in the reports available via download panel.

Using the conservation assessments from this project, we are working with RBG Kew, BKF and NBT to co-author a paper on the status and conservation of Thailand's rare or threatened, endemic tree species, to support development of a nationwide system to collect their seeds and conserve them, by encouraging their inclusion in forest restoration plantings.RED LIST MEETING BKFThe working group that reviewed the red listing of Thailand's endemic tree species at the Bangkok Forest Herbarium, November 2023 during the third phase of the project

Collaboration between FORRU-CMU and RBG-Kews continues to yield impactful results as the project enters its 4th phase (2024-26) under the fresh name: "The Global Tree Seed Bank: Unlocked" .

During this phase, FORRU-CMU is involved with: i) assessing the genetic structure of framework species populations; ii) assessing the supply and demand for seeds of framework tree species for restoration projects in Thailand; iii) determining the thermotolerance of framework species seeds (to build climate-change resilience into seed selection procedures), iv) developing planting-stock propagation procedures for data-deficient species and v) assisting Mount Ciremai National Park authority to establish their own FORRU in Indonesia. Planning seed collectionPlanning seed collection at the Doi Suthep tree nursery with FORRU-CMU nursery staff and the Kew scholarsThe project is providing three scholarships to CMU students to address these topics in their MSc or PhD projects. Nattanit Yiamthaisong is studying seed thermotolerance (to address climate change) for her PhD, whilst Sorayuth Liamchang is investigating the supply of and demand for seeds of native forest tree species across northern Thailand, to aid scaling up of forest restoration. Both students are also performing germination experiments and seedling growth trials on data-deficient tree species. Within the plant-genetics section of CMU Biology Department, Pimjan Narintarangkul Na Ayutthaya is studying gene transfer between planted and forest populations of framework tree species to understand how genetic diversity might be maintained during restoration projects.

A follow-up visit of FORRU-CMU staff to the Mt Ciremai is included in the project in 2026.
