The study showed a significant variation in the microbial population in the different study plots with the highest bacterial ( x108 cfu g1 ), fungal ( x104 cfu g-1 ) and actinomycetes ( x103 cfu g-1 ) population in shola forest in all the three ranges of Kodaikanal Forest Division. The population of soil microbes in Berijam and Poombarai forest range was also high under shola forests. This study has contributed to the understanding of soil microbial population in A. mearnsii invaded shola forests. |
