(seablite), a genus of halophilic plants of the family Chenopodiaceae. The plants are annual or perennial herbs, subshrubs, or shrubs. The leaves are usually alternate, narrow, and fleshy; the small, most often bisexual flowers are borne singly or in groups in the axils of the bracts. The perianth consists of five fleshy segments, which often have outgrowths when fruits are present. The fruit has a membranous carpel and contains vertical or horizontal seeds. Some species form two types of seeds: glossy black-brown seeds in the summer and early autumn and dull light-colored seeds in late autumn. The latter type of seed is the larger of the two.

There are approximately 100 species of seablite, distributed throughout the world except in the arctic zone. The plants grow along seacoasts and the shores of salt lakes and in various other salt-bearing places. The USSR has about 25 species, which grow mainly in southern regions. Most common are 5. pro-strata, an annual whose stems turn red, and S. microphylla, a strongly branched shrublet. Both species are usually found in clusters in wet solonchaks and solonchak lowlands. In late autumn and winter these and other species of seablite are eaten by camels and, to a lesser extent, sheep and goats. S. altissima is a weed and a ruderal plant. The ashes of seablite contain potash and sodium carbonate.

Our results indicated that seepweed (Suaeda salsa) tidal flats and reed ponds were the favored habitats by cranes in December and January, respectively.
At landscape scale, percentage of reed ponds and percentage of seepweed tidal flats showed a positive independent effect on crane abundance in both months.
Previous studies have indicated that red-crowned cranes prefer tidal grasslands and fishponds, and avoid salt ponds, seepweed marsh and farmlands in the reserve (Ma et al.
