AbstractDuring the last decade of a 37-year study of Downy Rattlesnake-plaintain (Goodyera pubescens (Willdenow) R. Brown) major herbivory by White-tailed Deer (Odocoileus virginianus) caused marked decreases in the sizes of two previously expanding populations. The 2012 drought resulted in an additional decline of one population. Because population growth depends on large flowerings, which occur only every four to eight years, recovery to 2002 levels would take several decades under favourable conditions.
