to be more of a plant that the presence of which indicates severe disturbance such as over-foraging and hyper-salinity, as is the case of the habitats of arctic geese where the forage plants are disappearing. Two locations are mentioned by United States Fish and Wildlife Service (USFWS) having problems from the ever-expanding populations of arctic geese and one from the Arctic Institute of North America of the University of Calgary or from an unpublished report from the Canadian Wildlife Service made available by the USFWS: Akimiski Island in the Canadian Northwest Territories where swards of Puccinellia phryganodes and Carex subspathacea have been replaced with dead willow stands and mudflats growing non-forage plant species, including Glaux maritima and Senecio congestus Cape Churchill Region and La Pérouse Bay, Manitoba where the expanding population of lesser snow geese has resulted in substantial changes to all intertidal habitats. In the vicinity of the coast extensive moss carpets are present and Senecio congestus and Salicornia borealis are widespread. Karrak Lake, Nunavut where growth in populations of Ross's geese (Chen rossii) and lesser snow geese (Chen caerulescens) has led to a decline in vegetative cover and areas with a 10-year or longer history of goose nesting than in areas with less than 10 years of nesting had more instance of exposed mineral substrate, exposed peat, and Senecio congestus. Tephroseris palustris is reported to be extirpated in Michigan.
