Abstract
The vegetation in the inland salt marsh at Al-Shiggah, in Al-Qassim district is characterized by its zonation. The different community types which characterize this vegetation are: Seidlitzia rosmarinus, Suaeda pruinosa, S. pruinosa- Salsola baryosma- Zygophyllum decumbens, Z. decumbens, and Hammada elegans. Differences in ground level, vertical elevation above the saline water table, moisture and salinity gradients and climatic aridity all contribute to the pattern of distribution, structure and composition of the vegetation.
