Results of the research carried out in the north-eastern region of Poland (10.2% of the total area of Poland), are presented in the paper. Three types of land s (plains of ice-dammed lake origin, moraine uplands, sandy outwash plains) occur in this region. The wetlands require individual methods of protection and use with consideration to their specific hydrological and biotopic features, natural values and condition. The main aim is to preserve the wetlands in the state maintaining their important role in the landscape. Endavaours should be directed towards protection or wetlands with the best vegetal ion cover including most or raised bogs, transitional and headwater peat lands, gyttja bogs with repeated bogginess, meadows with rich flora and swampy sections of river valleys. There is a need to re store these wetlands to their natural state. Some parts or the previously dewatered objects can be used for agricultural purposes.
