Astola Island locally known as Haft-Talar .(means seven rocks) is a small-uninhabited island with an isolated rock a short distance to the south of Pasni in the Northern Arabian Sea. The island has its significance for maintaining the genetic and ecological diversity of the area. The natural vegetation is composed of xerophytic species that are able to survive the arid climate. The vegetational composition of the island was analyzed using Bruan-Blanquet abundance classes. Biological and leaf size spectra of the flora were also determined.
Forty-one plant species were recorded and collected from Astola Island. The biological spectrum revealed that chamaephytes were the dominant life-form while the leaf size spectrum showed the dominance of leptophyll species. Many of the plants from the island are known to have medicinal value.
