Abstract:
Assessment on Biodiversity Surveys of Plant Community at Sakaerat Environmental Station, Nakhon Ratchasima. The study was emphasized details recording of biodiversity in Dry evergreen forest and Dry dipterocarp forest areas. The secondary data collection, surveyed and recorded for biodiversity analysis by statistic and computer system. The resulted to data comparative in importance areas. The results showed that the existing Sakaerat Environmental Station is Biosphere Reserves included biodiversity of conservation. It has 80 sq.km. and had natural forest. The results show that the Dry evergreen forest with the density of 744 trees/hectare, totally 136 species by Hopea ferrea were relative density, Hydnocarpus ilicifolius were relative frequency and Ficus sp. Were relative dominance with I.V.I., followed by Hydnocarpus ilicifolius and Walsura trichostemon. For the Dry dipterocarp forest with the density of 563 trees/hectare, totally 83 species by Shorea obtuse and Shorea siamensis were relative density, Pterocarpus macrocarpus were relative frequency and Lophopetalum duperreanum were relative dominance with I.V.I., followed by Shorea obtuse, Shorea siamensis and Pterocarpus macrocarpus and so on. The Shonnon-Weaver index (H) in Dry evergreen forest was 5.322 and Dry dipterocarp forest was 4.231. This study was totally 307 species in Dry evergreen forest 66 family 233 species and Dry dipterocarp forest 53 family 124 species and reserved species 97 species and special reserved species 2 species followed by Zanthoxylum limonella and Tarenna hoaensis.
