Abstract:

The objective of this study is to measure the floristic diversity in coffee agroforests and adjoining forests as well to know the effect of different landholding sizes of coffee farms in Kodagu district, Western Ghats of Karnataka. We collected the data on trees, shrubs and herbs from 50 sample plots of 0.16 ha. Each and analyzed for various diversity parameters. Results revealed that Shannon’s (H') was highest in adjoining forests (2.48) compared to that of coffee agroforests (1.92). On the other hand, Simpson’s (D) value recorded in adjoining forests lower (0.11) compared to coffee agroforests (0.28). This study revealed that the considerable number of tree species are being managed and conserved in coffee agroforests, similar to that of adjoining natural forests. IVI revealed that Grevillea robusta was found to be most dominant species in coffee agroforests, while in natural forests, Terminalia tomentosa species was dominant. Considerable variation in various diversity parameters was noticed among different landholding sizes with higher diversity in medium holding compared to small and large sized coffee plantations. Contrary, higher basal area (m2 ha–1) was recorded in large farms compared to small and medium sized coffee farms. We found that coffee agroforests resembled to that of adjoining forests suggesting that traditional coffee farms are being managed sustainably and can help to conserve the biodiversity.
