Purpose: In this study we try to measure the environmental changes that took place in the study area Musawarat Elsufra. We try to find the causes of these changes and establish a comparison of the present and past vegetation of the area.
Methodology: Present vegetation was investigated using fresh plant materials for pollen analysis. Fossils were taken from the ‘hafir’ (basin) to study the fossil pollen grains at different soil depths. Soil surface samples were taken to analyse the chemical and physical properties of the soil.
Findings: The pollen analysis of the samples taken from the hafir (basin) of Musawarat reveals that there are 21 species belonging to 16 families. The dominant families were Cyperaceae, Commelinaceae, Mimosaceae and Amaranthaceae.
Value: Comparison of past and present vegetation maintains the causes of environmental change and ensures sustainable development in arid regions.
