Using aerial photographs taken in 1955 and 1985, this study surveys the vegetation composition and recent land-use history of Maktala, an arid region located about 400 km west of Alexandria. Within this period, a doubling of cropping lands and a six
-fold increase of orchards was noted. 5 plant communities were identified. The floristic composition of the communities show differences when compared to older vegetation data. These differences are discussed in the light of increasing land degradation
Relationships between environmental factors and annual vegetation were investigated in a landscape dominated by linear dunes near Nizzana, Western Negev Desert, Israel. This study had two purposes: to provide data on the magnitude of variation
