Daftar Isi:
- Coastal area with its high temperature, high soil salinity, strong winds and sandy soil structure may cause environment condition which limits the survival and growth of undergrowth. Such an extreme environment may also affect the pattern of distribution of the undergrowth, such as a random, regular or clustered pattern. This study aims to determine the composition and distribution patterns of the undergrowth under Cemara Udang stand in a coastal area at Karanggadung, Kebumen, as well as the function of the undergrowth. Data was collected using line transect method, in which a systematic sampling with random start was utilized to determine sample plots locations. Line transects were perpendicularly made for 5 m in wide and 50 m in length to the shoreline. The distance between lines was 100 m. Each of the lines was divided into 10�10 m plots, and undergrowth were observed from 2�2 m sample plots located diagonally in the 10�10 m plots. The total number of the sample plots is 30 plots. Types of undergrowth were indentified and the coverage magnitudes of each species were estimated. Data was analyzed by calculating Importance Value Index (IVI) of each of the species, as well as Dispersion Index and Chi-Square for determining the distribution pattern. There were 15 undergrowth species (within 11 families) found in the Cemara Udang stand. Spinifex littoralis, Ermeleria sonchyfolia, Isachne pulhella Cyperus pygmaeus and Calothropis gigantea dominated the area, with the IVI of 98.7 %, 16.8 %, 15.6 %, 14.1 %, and 11.5 %, respectively, while 10 other species less than 10 %. Among the species, 4 species distributed in random pattern and 11 species distributed in clumped pattern. The undergrowth species were useful and beneficial for the community in term of life support and ecology. The undergrowth under Cemara Udang Stand in a Coastal Area at Karanggadung, Kebumen were used for animal fodder, medicine and as sand binder in the sand dunes. The environmental factors strongly affected the presence of the undergrowth species.
