Ecology of sand dune vegetation in relation to beach stability at Miramar, Goa

A.G. Untawale, S.A. Nair

Abstract



About 67 species of plants under 62 genera belonging to 33 natural orders occur in the sand dunes. Observations made at 3 points revealed that the Light House point and Caranzalem Beach have a luxuriant dune flora, while Gasper Dias proper is poor in vegetation. Psammophytes help in maintaining the beach stability of Miramar. The rainfall, temperature, wind speed, moisture and humus content of the dunes are responsible for the growth of plants. Erosion provides an adverse effect on the flora and is prevalent in certain parts of the Caranzalem Beach. The vegetation in sand dunes is mostly psammophytic and Ipomoea pescaprae is the most dominant species. The other species present are Spinifix squarrosus and Cyperus arenarius followed by many more
