Bottom Brook Estuary
Bottom Brook Estuary is located at the southern end of
Lewisporte Harbour and contains ideal feeding and staging habitat for numerous waterfowl and shorebird species.
During initial field surveys, a number of waterfowl species were identified including the ring-necked duck, American black duck, greater yellowlegs, ring-billed gull, herring gull, great black-backed gull and common tern.
Songbird species included gray jay, white-throated sparrow, black-and-white warbler and ruby-crowned kinglet. Other species recorded in the area by a local birder were the common loon, Arctic tern, Caspian tern, common goldeneye, red-breasted merganser, spotted and semipalmated sandpiper, osprey and bald eagle.
The proposed management unit, where the fresh water of Bottom Brook flows into the salt water
of Burnt Bay, contains nutrient rich brackish water, dispersed throughout the area by water currents, tidal movements and wind.
Continuous mixing of salt and fresh water creates a highly productive environment for a large variety of wildlife species, making this area important habitat within the Town of Lewisporte. Vegetation surrounding the estuary consists of common softwood and hardwood species, such as black spruce, balsam fir and white birch.
The estuary possesses little emergent vegetation, consisting primarily of scattered rocks with mud and sand substrate, providing excellent habitat for insects, worms, mollusks and crustaceans which as a nutrient-rich food source for may waterfowl and shorebird species.
