As always all of our North Texas Master Naturalist (NTMN) programs are free and open to the public.
In 2004 a small group of North Texas Master Naturalists began a field study with Dr. Marcy Brown Marsden of the University of Dallas on native non-photosynthetic, mycoheterotrophic orchids. Each summer from mid-May through late July a team of North Texas Master Naturalists explore along several trails in Cedar Ridge Preserve looking for the flower spikes of Hexalectris orchids. The data base of information that has been compiled has greatly expanded the scientific knowledge of these unusual, beautiful terrestrial orchids. The May Meeting presentation will share basic information on mycoheterotrophy, Hexalectris orchids, the steps of the annual orchid censusing, and the new knowledge that this work has added to the world of botany.
Stephanie Varnum, a native of Pennsylvania, has lived in Texas for almost 50 years. “My parents instilled a love of and deep respect for nature in me. It’s been my joy to pass that heritage along to my husband, Jim, our children, and six grandchildren. I became a Texas Master Naturalist in 2002 and discovered my passion for Citizen Science and ecological studies. Since 2005, I have done field research on native orchids in Texas with a focus on non-photosynthetic, myco-heterotrophic orchids.”
