SUMMARY
Soil samples were collected using a grid system spanning from natural forest areas to more degraded cultivated zones in order to monitor biodiversity changes along a gradient of land-use intensification. Organisms concerned were the microscopic fungi. Soil samples were collected at 3 and 6 m radius circles around each point. Overall, 107 points were sampled of which 40, from the 8 land use types were analysed. Fungi were identified based on both macroscopic and microscopic morphological characteristics. Total microflora identified from the points showed that 4-year-old teak plantations were less rich in fungi, whereas 10-year-old teak plantations were richer in fungal flora. When grouping the communities into morphological units or genera, it appears that genera such as Aspergillus, Penicillium, Trichoderma and Fusarium were the most frequently encountered and were present across the landscape. However, other fungi genera, such as Sclerotium, Acremonium, Geotrichum, Pythiopsis, Phytophthora, were rarely found in this environment.
