Small whorled pogonia (Isotria medeoloides) is a small orchid listed by the United States Fish and Wildlife Service (USFWS) as threatened throughout its range.

It is most identifiable while in flower and can easily be confused with other plants that share the same habitat such as large whorled pogonia.

According to the USFWS, known populations of small whorled pogonia are now present in only 143 counties in 18 states. The USFWS recommends survey by a qualified botanist where projects are located within a county where potential habitat exists and the species may be present. Survey windows vary from state to state but generally run from early May through the end of July, with results being valid for two years.

If you have not yet conducted small whorled pogonia surveys, it’s not too late. Reach out to EDGE’s Shawn McKinley or Larry Brewer for #furtherinsight!
