The water supply of a bog comes almost exclusively from precipitation, resulting in a nutrient-poor, acidic environment. As a bog has limited external drainage, the surface is frequently covered with small ponds.
Bogs are the most common form of wetland in the province.
There are several types, ranging from extensive blanket bogs in Cape Breton to small, flat deposits found throughout Nova Scotia. Bog plants are extremely interesting, and include several species of Sphagnum moss, Reindeer Moss lichen, orchids and insect-eating plants.
