J1b – Birch mire woodlands: 
Mire woodlands dominated by scattered birch trees (closure 40-80%). The typically small stands occur in closed drainage basins and old oxbow lakes with stagnant water. Soil water is high (reaching the surface), the soil is peat, or peaty with ongoing peat formation. Mire and marsh species are usual, sedges are dominant in the herb layer, and the moss cover is significant. One of the rarest habitat of Hungary (21 ha). The stands can be found in the Északi-középhegység (Mátra: Sirok, Putnoki-dombság: Kelemér) and on Szatmár-Beregi-sík, as well as in the southern part of Nyírség. Besides the drying of former mires the rarity of the habitat can especially be explained by the natural rareness of suitable sites.
