Räme is a landscape term in Finnish geography that designates a type of mire or fen with relatively mineral-rich, waterlogged soils. It forms part of the mire continuum alongside more peat-dominated bog areas (so) and other wetland habitats. Räme soils typically contain thinner peat layers and are influenced by groundwater and surface water, which sustains higher mineral content and different vegetation than peat-rich mires.

Geography and ecology: Räme landscapes are generally flat or gently undulating and experience persistent wet conditions due to poor drainage and shallow groundwater. The vegetation is dominated by sedges and grasses, with bryophytes such as mosses present and, often at the edges or in higher micro-sites, scattered trees or shrubs. The habitat supports a range of specialist invertebrates and birds adapted to damp, nutrient-rich conditions, and it contributes to regional biodiversity as part of mosaic mire complexes.

Human use and conservation: Historically, räme areas have been drained or altered for forestry, agriculture, and peat extraction, which can modify hydrology and reduce biodiversity. In recent decades, many räme landscapes have come under protection as part of mire conservation efforts and nature reserves, focusing on preserving hydrological functions, carbon storage in peat, and the associated flora and fauna.

Distribution: Räme is a common landscape element in boreal Finland and occurs in neighboring Sweden and Russia where extensive mire networks developed under post-glacial conditions. It forms a characteristic component of northern wetland systems and influences local land use, hydrology, and ecology.
