There is no congruence in diversity of the three groups of organisms studied. It is inferred that their differences in biological and ecological characteristics as well as their ranges of dispersal are responsible for the distinct patterns of distribution in the landscape. It is proposed that the strategy for biodiversity conservation should consider landscape-level conservation in order to capture the range of biodiversity that exists outside the formal reserve network in Kodagu. While maintaining the integrity of the strictly protected forest reserve; of traditionally conserved sacred forests; and of privately owned coffee plantations is essential, conservation practice should emphasise the involvement of local communities in management of landscape rather than imposing biodiversity conservation by force.
