Response Statement - Nodding Pogonia
This small showy orchid of rich woodland soils undergoes variable periods of dormancy. In Canada, this species is known from only two populations in southwestern Ontario, one of which has not been observed in more than 20 years. About 1400 flowering stems were documented at one site in 2008 during a year of high rainfall, in contrast to a decade previously when the Canadian population was documented as consisting of only 50 individuals. Although grazing by deer has been reduced, invasive plants have contributed to a loss in habitat quality and exotic earthworms are likely the cause of the reduction of the organic layer of the forest floor. Chance events could also impact the population.
