DescriptionGenetic variation is the most powerful factor in ensuring the long term success of trees and forests in times of change. In order to protect against loss of genetic variation from threats, including pests and diseases and climate change, the Royal Botanic Gardens, Kew, is developing a national tree seed collection for the United Kingdom.
This paper describes the authors methodologies and experiences of developing the national collection: firstly, forming species target lists using plant health risk and conservation assessments; then, developing national sampling strategies based on the distribution of target species in biogeographic zones; and, finally, how collecting strategies were designed to capture and preserve genetic variation within populations.
Additionally, we discuss social and ecological factors taken into account when developing and implementing the sampling program. These include phylogeography; the history of woodland management, ownership and fragmentation; and introgression risks from plantation and garden escapees. Finally citizen participation is discussed.
