BGCI US has published a new guide, Building living plant collections to support conservation (3MB). The guide features work done by the Montgomery Botanical Center, including genetic evaluation of the Sinkhole Cycad.
This guide is designed to provide a general blueprint to help strategically develop conservation collections. Many endangered plants are considered exceptional species, which do not store well in seedbanks, and thus must rely on living collections for conservation. Quoting from the guide:
"Your garden has the power to ensure extinction isn't an option by strategically building and using your collection to support conservation of threatened species. In doing so, you contribute to the Global Strategy for Plant Conservation and support global efforts to halt the continuing loss of plant diversity."
