Kenya has an ambitious plan to grow 15 billion trees by 2032; however, the major challenge remains the availability of and accessibility to quality germplasm resources in sufficient quantities to meet this goal. Restoration seed banks have the potential to catalyse the country’s landscape restoration by ensuring a consistent supply of high-quality native tree seeds for biodiversity, climate-resilience and community livelihood. The Centre for Ecosystem Restoration Kenya advances ecological restoration in Kenya by empowering community seed collector networks and integrating threatened tree species into planting programmes through capacity building on best practices of native tree germplasm and mentoring projects to embrace best practices of ecological restoration. Through the Terraformation and Franklinia projects, the CER-K has trained 210 community members, produced and distributed three and two tons, respectively, paid KES 3 million to 20 seed/seedling producers and integrated 37,400 threatened tree species in planting programmes into 11 restoration projects to support the Global Biodiversity Standards (TGBS). This integrated approach to community stewardship, coordinated germplasm supply systems and mentoring, the CER - Kenya restoration seed banks, accelerates the quality, scale, and sustainability of Kenya’s tree-growing commitments and long-term ecological resilience, though the gap remains enormous.
