Tim Pearce is focussed on developing the seed conservation programmes across Kew's African partners, delivering Kew’s strategic target of securing seeds from 25% of the world’s flora by 2020.
Of the c.75,000 African plant species, we currently hold c.20,000 African seed collections representing c.11,000 taxa. He has set an ambitious 5 year target of securing collections from a further 10,000 taxa held to international seed banking standards across Kew's African partners.
As well as this seed collection effort, he is continuing to develop the MSBP Data Warehouse in order to harvest data from those non-duplicated seed collections held across the MSBP.
He has a particular interest in the Genus Kalanchoe and am undertaking phylogenetic and seed trait analysis of our collections held at Kew.
Kew’s global seed banking network, the Millennium Seed Bank Partnership (MSBP), is the largest ex situ plant conservation programme in the world. Our focus is on plant life faced with the threat of extinction and plants of most use for the future.
Working with our network of partners across 100 countries and overseas territories, we have successfully banked approximately 15.6% of the world's wild plant species. Collections are preserved at the Wellcome Trust Millennium Building at Wakehurst and around the world in our partner seed banks. The collections and the vital associated knowledge enable innovation, adaptation and resilience in agriculture, horticulture, forestry and habitat restoration.
Through the Millennium Seed Bank Partnership, we aim to achieve the following:
1. Conservation of threatened, range restricted and useful plants
2. Expansion of the network of countries and partners working under common seed conservation standards to increase the quality and genetic diversity of collections.
3. Strengthen the seed collections of the UK flora, with a focus on multi-provenance collections of woody species and the threatened flora.
4. Research the different strategies needed to sample genetic diversity, and conserve seeds that cannot withstand desiccation and freezing.
5. Track progress of global seed conservation towards banking 25% of the world’s plant species; this equates to approximately 75,000 species.
The targets of the Millennium Seed Bank Partnership help to achieve Target 8 of the Global Strategy for Plant Conservation, one of the Cross-Cutting Issues of the Convention on Biological Diversity. They also contribute towards Targets 2, 13 and 15 of the UN Sustainable Development Goals.
“Assessing the impact of climate changes on germination potential of selected species of Kalanchoe”. The study will analyse our existing data and run new germination tests to firstly establish the optimum temperature range for germination. We will then take selected species and run additional germination tests using our state-of-the-art facilities at the Millennium Seed Bank in order to determine how shifting the germination conditions to represent likely climate change scenarios. We will determine if such predicted changes in prevailing climatic conditions will have an impact on germination success in the wild. Germination success is one factor in the successful recruitment of population cohorts in wild populations and so an insight into this potential impact is vital to considering in-situ conservation decisions in the future.
