1. Impact of shade management on avifaunal diversity Case study of the coffee agroforestry systems of Kodagu, Western Ghats (India) Harish T.T., Prakash,, C.G. Kushalappa WAC Conference – Nairobi 2009

2. August 27, 2009WCA Conference, Nairobi2 Introduction  Avian community studies as tools for monitoring forest and agroforest ecosystems.  Few reports available on bird diversity of Western Ghats.  Landscape level dynamics question the ecological sustainability of the production system  Complementing existing tree biodiversity assessments

3. August 27, 2009WCA Conference, Nairobi3 Objectives To determine and compare the similarity in bird species composition across semi- evergreen and moist deciduous vegetation types. To assess the impact changes on the canopy cover have on bird species diversity. To study the community structure and organization of bird species based on their food and feeding habitat. To prepare a checklist of birds of Cauvery watershed area.

15. August 27, 2009WCA Conference, Nairobi15 In a nutshell The management practices in coffee plantation to give importance for retention of native tree species in the shade layer and native forests in the landscape are necessary. Coffee plantations play an important role in the maintenance of diverse bird populations in Kodagu, and as a dry season refuge for mobile populations of omnivores, frugivores and nectarivores.
