A raised bog located in Ķemeri National Park, Jūrmala, Latvia, formed approximately 10,000 years ago in the postglacial period and is now a popular tourist attraction
Precipitation accumulates in many bogs, forming bog pools, such as Koitjärve bog in Estonia

A bog is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss.[1] It is one of the four main types of wetlands. Other names for bogs include mire, quagmire, and muskeg; alkaline mires are called fens. They are frequently covered in ericaceous shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink.[2]

Bogs occur where the water at the ground surface is acidic and low in nutrients. In some cases, the water is derived entirely from precipitation, in which case they are termed ombrotrophic (cloud-fed). Water flowing out of bogs has a characteristic brown colour, which comes from dissolved peat tannins. In general, the low fertility and cool climate result in relatively slow plant growth, but decay is even slower owing to the saturated soil. Hence, peat accumulates. Large areas of the landscape can be covered in many meters deep in peat.[1][3]

Bogs have distinctive assemblages of animal, fungal and plant species, and are of high importance for biodiversity, particularly in landscapes that are otherwise settled and farmed.
