 It has been noted that populations of this lichen can decline even in protected areas, which has been linked to air pollution and introduced herbivores, such as moose.The Atlantic population of the "E. pedicellatum" is protected in Canada under the Federal Species at Risk Act (SARA), and is the focus of an ongoing recovery strategy.Efforts are being made, through land purchases and agreements with landowners, to formally protect areas of forest that are home to this rare species.
