Marshes are part of the ExtrabiomesXL mod.
Marshes are very flat with little, if any, elevation. they are mostly composed of water and grass blocks, there are almost no trees in marshes, mostly grasses grow there. It is not recommended to live here, as there is not much land to build on, and the excessive pattern causes lag on some computers. Typically try to avoid them, as they are hard to traverse as well.
