Abstract: | This study was conducted at Uswetakeiyawa on the southwestern part of Sri Lanka. Twenty-two families, 42 genera and 52 species were recorded from the sandy shore vegetation. Approximately 3.8 % (2 species) were found to be endemic and 67.3 % (35 species) were found to be of medicinal importance. Ipomea pes-capre and Spinifex littoreus were the most abundant species at the study site. The average value for all the zone combinations was β = 0.693, and the highest similarity value was ISj = 0.276, corresponding to two non-contiguous zones. The results show that a variation in plant diversity is to be found across the gradient. The typical zoning nature of the sandy shore vegetation has been disturbed due to on-going development in Uswetakeiyawa. New policy decisions should be taken to restrict development activities in Uswetakeiyawa in order to protect the sandy shore vegetation. |
