This association includes open low-growing grasslands dominated by Puccinellia distans (P. limosa does not occur in the Czech Republic). They are found in drier parts of saline sites that are flat or slightly elevated and do not contain wet depressions. Soils are slightly wet in spring, but dry out in summer. These grasslands were traditionally grazed or trampled. They occurred in several places in the dry lowlands of southern Moravia, but only four localities are still extant.
