She’ll also cover the extensive renovation of the Heckman Rock Garden and stories of successful cultivation from lowland Missouri natives to high-elevation plants.

Christina Alba
Conservation Biology at Denver Botanic Gardens—with a Glimpse Beyond the Garden Gate
I will give an overview of our DBG department’s work, and expand more deeply on my own work within the larger framework of what goes on department wide. I can then switch gears to the Greece travelogue and how I uploaded all my plant observations from Greece to iNaturalist. Much of the conservation work we do in the Research department happens in wild systems across Colorado highlight how we use iNat as a platform to engage citizen scientists and do outreach.
