Site description The Babbage River and Spring River deltas are located on the Beaufort Sea along the Yukon coast. The site encompasses about 15 km of coastline and extends out 12 km into the Beaufort Sea to include Kay Point and Phillips Bay. The site continues about 1 km inland, except at the Babbage River delta where it continues up to 5 km inland. The larger Babbage River flows westward into the east side of Phillips Bay, while the Spring Rivers empties into the bay about 8 km to the west, and approaches from the south. Within these deltas, the dominant habitats include ponds, channels, grass-sedge wetlands, salt marshes, and tidal mudflats. Along the coast, gravel and sand beaches dominate, while further inland arctic tundra consists of dwarf shrubs, sedges, and herbs.
