The main reasons for the spread of swamps.

The main reason for the spread of wetlands is certain climatic conditions, which contribute to the preservation of a large amount of moisture in the soil. Basically, swamps are common in the northern hemisphere of our planet, and most of them are in the taiga zone. The climate here is cold, with a lot of precipitation and frequent rains. In lowlands, in the absence of water runoff, as well as when lakes and ponds are overgrown, the area becomes swamped, and numerous streams and rivers, as well as precipitation, contribute to additional accumulation of moisture. Human activities also affect the appearance of swampy areas.
