Platanthera leucophaea
Germinating Platanthera seed is of special interest to me because of the decline of our beautiful endangered prairie orchid, Platanthera leucophaea.
I work part time for our Bureau of Endangered Resources (Wisconsin DNR), and survey for prairie white fringed orchids (state endangered and federally threatened). In 2006 I collected seed to germinate in vitro and scatter in our prairie restoration on our farm. The laboratory photos were taken last month as I tried to catch up on sowing seed collected in 2007. Included are some photos of the young seedlings in the flask. We believe that monitoring populations alone is not enough to protect the species since some populations are under threat by lack of management and, in some unfortunate cases, herbicide drift from adjacent farmland. We need to spread seed into suitable habitats to reduce the risks. The highest population of P. leucophaea in Wisconsin (hundreds of plants) occurs at a site that was formerly in row crops, and the seed either is either much longer lived than we suspect or seed drifted in from a nearby population when the fields were enrolled in the Conservation Reserve Program (CRP). Fortunately those sites are managed privately by owners who love the orchids, and they have received permanent protection as State Natural Areas.
