  abstract = {{T}raditional shade coffee plantations of {K}odagu district, in the {W}estern {G}hats of southern {I}ndia, harbor a high density and diversity of trees. {L}ocal farmers appreciate native biodiversity, but plantation economics and public policies drive them to gradually replace the original diversified cover with exotic shade trees such as {G}revillea robusta, which grows fast and can be easily traded as timber. {I}n order to identify and recommend native timber trees with fast growth rates, we compared the growth performance of four common native species against that of {G}. robusta, by fitting steel dendrometer bands on 332 shade trees. {R}esults showed that in general {G}. robusta had the fastest growth rates, but large trees of the native {A}crocarpus fraxinifolius had faster growth in the wet western side of the district. {C}omputer projections of long term performance showed that most species were influenced by bioclimatic zone. {S}pecies-specific local environmental effects also occurred, including competition from coffee bushes for {A}. fraxinifolius, influence of aspect for {G}. robusta, and management block effects for {L}agerstroemia microcarpa. {O}ur results show that native species potentially could produce timber at rates equivalent to those of exotic species. {H}owever, as in many tropical countries, data on growth rates of native trees within mixed-cover plantations are scarce and this study underlines the urgent need to screen for fast-growing species. {S}uch information provides a strong basis for recommending appropriate changes in public policies that would improve tree tenure security and encourage farmers to grow more native species.},
