Abstract:
The vegetation of waterlogged and saline areas of Hazro, District Attock was studied during July, 1986 using line transect method. Three plant communities namely Imperata cylindrica-Cynodon dactylon-Equisetum ramosissimum, Imperata cylindrica-Cynodon dactylon-Typha angustata and Cynodon dactylon-lmperata cylindrica- Typha angustata were recognized on the basis of summation values. All the three communities were similar in composition due to similarities in habitat and environmental conditions. The physical and chemical analysis revealed that soil in the first and third community was clay-loam while it was sandy loam in second community. The total soluble salts (TSS), electrical conductivity (EC) and other minerals were generally higher in the surface than in the deep layers. The soils had higher TSS, EC, P and K in the second community while CaCO3 and organic matter was higher in the first and third communities. There were 58.06% therophytes, 29.03% hemicryptophytes and 12.90% geophytes. It is evident that all the three communities are the different seral stages of the same succession.
