Abstract: Tropical forest restoration in open areas is often slowed by limited seed rain and unfavorable conditions for tree seedling establishment. Isolated remnant trees, a common feature of degraded anthropogenic landscapes, may alleviate these problems. Remnant trees increase seedling recruitment in part by attracting frugivorous animals, which amplify the quantity and diversity of seed rain. I examined the sensitivity to human disturbance of volant frugivore visitation to remnant trees in a highly disturbed site of Tamil Nadu, India. Frugivorous bird and fruit bat visitation to banyan trees (Ficus benghalensis) was recorded across a gradient of human impact, from urban areas to forest edge. Variables quantifying disturbance, including building cover and the amount of vegetation surrounding banyan trees, had relatively little effect on frugivore visitation. For both groups of animals, the most important variable predicting visitation was the size of the focal tree. In my study site, tree seedling abundance and species richness is significantly higher under remnant trees compared to open areas. These results demonstrate that in some regions animal seed dispersal, one of the mechanisms leading to remnant tree function as recruitment foci, may be resilient to disturbance . Incorporating animal seed dispersal services into reforestation plans may increase the efficiency of ecological restoration.
