 The low-lying, wetter areas are similar to the surrounding Beringia lowland tundra ecoregion but the uplands are generally drier and dominated by sedges such as Eriophorum vaginatum and scrub such as the ericas Arctostaphylos alpina, Vaccinium vitis-idaea or Empetrum nigrum or mountain-avens (Dryas octopetala) and dwarf arctic birch (Betula nana).Sheltered valleys will have some spruce or poplar trees picea glauca and populus balsamifera.The Seward Peninsula is vulnerable to fire when the lichens dry out in summer 

Birds of this coast include the rare shorebird bristle-thighed curlew (Numenius tahitiensis) which breeds only in Alaska, spectacled eider (Somateria fishceri), a number of turnstones (Arenaria spp.
