Bog
A bog is a wetland type that accumulates acidic peat, a deposit of dead plant material. The term peat bog in common usage is not entirely redundant, although it would be proper to call these sphagnum bogs if the peat is composed mostly of acidophilic moss (peat moss or Sphagnum spp.). Lichens are a principal component of peat in the far north. Moisture is provided entirely by precipitation and for this reason bog waters are acidic and termed ombrotrophic (or cloud-fed) which accounts for their low plant nutrient status. Excess rainfall outflows giving bog waters a distinctive tan colour.
Bog habitats
Bogs are challenging environments for plant life because they are low in nutrients and very acidic. Carnivorous plants have adapted to these conditions by using insects as a nutrient source. The high acidity of bogs and the absorption of water by sphagnum moss reduce the amount of water available for plants. Some bog plants, such as Leatherleaf, have waxy leaves to help retain moisture. Bogs also offer a unique environment for animals. For instance, English bogs give a home to the boghopper beetle and a yellow fly called the hairy canary.

Some bogs have preserved ancient oak logs useful in dendrochronology and they have yielded extremely well-preserved bog bodies, with organs, skin, and hair intact, such as Tollund Man and Lindow man, buried there thousands of years ago after apparent Celtic human sacrifice.
