Low marsh is a tidal marsh zone located below the Mean Highwater Mark (MHM).

The reserve covers the low, marshy wetlands of the Kuma delta, as well as the entirety of Kizlyar Bay. Tyuleniy Island lies to the east of the reserve, 43 km (27 mi) from the coast, just outside of the bay. To the north the landscape changes to semi-desert. [1] The reserve includes four sectors that are disconnected from the Kizlyar Bay territory:
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).
