Orchids on the Edge: Conservation in a Changing World 

Saturday, March 6 | 11:00 AM- noon

Instructor: Dr. Lawrence Zettler

Live, virtual program 

$10 per member, $25 per nonmember 

Every orchid on this planet – from showy epiphytes that grow on trees in tropical rainforests, to hardy terrestrials found here in the Midwest – needs a fungus to grow and survive.  Many also require specific insect pollinators which are also necessary for the orchid’s reproduction and survival.  About one half of the 27,000+ orchid species worldwide are now vulnerable to extinction, in part, because of their acute sensitivity to environmental changes.  In this presentation, Dr. Lawrence W. Zettler, Hitchcock Professor of Biology at Illinois College, will delve into the life history of the orchid from seed germination into maturity, including examples as the Ghost Orchid of Florida and Cuba, Dendrophylax lindenii, subject of Susan Orlean’s best-selling novel, The Orchid Thief, and Hollywood movie, Adaptation.  The talk will also showcase some of the orchids that grow in the tropics such in Madagascar, and what is currently being done to conserve the rarest species, as well as some tips on orchid growing and care.     

Dr. Zettler studies the effects of fungi on orchids in order to aid conservation efforts in the Orchid Recovery Program at Illinois College, growing orchids from seed in the laboratory using the fungi they require and consume in nature.
