Abstract:The effects of fragmentation and overstorey tree diversity on tree regeneration were assessed in tropical rain forests of the Western Ghats, India. Ninety plots were sampled for saplings (1–5 cm diameter at breast height (dbh); 5×5-m plots) and overstorey trees (>9.55 cm dbh; 20×20-m plots) within two fragments (32 ha and 18 ha) and two continuous forests. We tested the hypotheses that fragmentation and expected seed-dispersal declines (1) reduce sapling densities and species richness of all species and old-growth species, and increase recruitment of early-successional species, (2) reduce the prevalence of dispersed recruits and (3) increase influence of local overstorey on sapling densities and richness. Continuous forests and fragments had similar sapling densities and species richness overall, but density and richness of old-growth species declined by 62% and 48%, respectively, in fragments. Fragments had 39% lower densities and 24% lower richness of immigrant saplings (presumed dispersed into sites as conspecific adults were absent nearby), and immigrant densities of old-growth bird-dispersed species declined by 79%. Sapling species richness (overall and old-growth) increased with overstorey species richness in fragments, but was unrelated to overstorey richness in continuous forests. Our results show that while forest fragments retain significant sapling diversity, losses of immigrant recruits and increased overstorey influence strengthen barriers to natural regeneration of old-growth tropical rain forests.

Degraded and overgrazed grasslands and meadows is a critical issue affecting productivity of open grazed animals. Traditional forest dwelling communities are knouin to conserve their surrounding biodiversity, mostly with cultural perspectives and this indirectly preserve the resources for future generations. Fakhan Raans are privately owned grass sanctuaries which are protected from open grazing and other disturbances like ores and harvested sustainably. This is the first study of this tradition unique to the Western Ghats. A surv‹nJ mas conducted in 13 hamlets belonging to 11 village panchayats in Akole taluka of Maharashtra. Duffy structured intervieuis mere conducted in all households of selected hamlets in a door-to-door manner. Using a detailed questionnaire we collected data on livestock, raakhan ran holdings and changes within f«s/ decade. The tradition is not unique to a particular community. lt is a sus/oinflhfe practice considering that grass is harvested after seed dispersal and some areas are lefl unharvested. The Raakhan Rans have been reducing over the last decade, though still maintained by large headers for fodder security. Special eJorfs are required to conserve the tradition and link it to the protection of grassland biodiversity and dependent livelihoods.
