In the present study, soil algal community inhabiting in two different forest types i.e., pine forest and subtropical broadleaf forest (Mawphlang sacred grove) in East Khasi Hills District of Meghalaya have been investigated. Light availability to the forest floor and soil physico-chemical parameters were examined. A total of 124 taxa of soil algae were recorded from both the forests. Members from Chlorophyta, Xanthophyceae, Eustigmatophyceae contributed the most (72%-80%). Mawphlang sacred grove was characterised by more abundance of Cyanobacteria (21%) and less diatoms (2%), while in pine forest diatoms abundance was high (20%) and less Cyanobacteria (13%). Algal species composition differed significantly between the two forest types. Correlation between species diversity with light and soil characteristics indicated that vegetation along with pH, moisture content, organic carbon and nitrogen played important role in determining the composition of algal community.
