They have to cope with very unfavorable conditions, however, ranging from permanent waterlogging, the lack of nutrients, to a generally cold environment with wide fluctuations in temperature. Due to these extreme conditions, peat bogs are home to many rare plant and animal species not often encountered elsewhere.
Peat bogs are remarkable. Thanks to specific types of cells called hyalocysts, they can hold a huge amount of water, which rises through them. They also have the special ability to grow back continually, while their lower parts die off, accumulate, and form peat.
So far, we’ve focused mainly on the importance of peat bogs in terms of their carbon retention properties, but we mustn’t forget that they are remarkable natural habitats with highly specialized species from both the plant and animal kingdoms.
