The study was conducted in Coffee plantations under two land tenure systems in semi evergreen and moist deciduous vegetation types in Virajpet taluk of Kodagu district. Structural components of canopy cover namely density, basal area, volume and size class distribution of coffee plantation was well maintained under unredeemed plantations and semi evergreen vegetation compared to redeem and moist deciduous vegetation. Species richness and diversity of native tree species was higher in unredeemed coffee plantation in semi evergreen vegetation, while the richness and diversity if exotic tree species
