Alpine Plants and Seed Collection
Press 'cc' on video player to turn on subtitles.
Alpine ecosystems are particularly vulnerable to climate change. The Denver Botanic Gardens are seeking to protect rare species from these regions, banking seeds from multiple Alpine populations by maternal line. However, collecting seed from these remote areas comes with multiple challenges. Seed production is dependent on the previous year's winter weather, there is a short window for flowering and seed setting, the phenology changes rapidly, and many sites are difficult to reach.
After gathering seed, researchers at Denver Botanic Gardens perform germination trials and grow seedlings to be reintroduced. Plants are also added to the living collections at Denver Botanic Garden and the Betty Ford Alpine Botanic Gardens to further preserve these rare species.
