Description

  • This article evaluates whether the installation of bat roosts into abandoned pasture sites can attract frigivorous bats into pasture areas and encourage seed rain of early-successional plant species.
  • At the La Selva Biological Station in Costa Rica, the authors set up bat roosts simulating hollow tree trunks in areas of continuous forest and disturbed areas (small forest fragments (< 3 ha) or tree stands in pasture at various distances from forest).
  • All roosts were placed in shade to avoid excessive heat. Authors captured bats and collected feces to evaluate the diversity of bats and their food resources between habitats.
  • The authors found that bat roosts in the disturbed areas were colonized by frugivorous and nectarivorous bats and augmented the seed rain.
  • The seed rain was higher near the artificial roosts than at control sites, and many of the seeds belonged to early-successional plant species.
  • Ten species showed comparable levels of colonization in the artificial roosts compared with natural roosts. Sixty-nine seed species were transported to artificial roosts in the disturbed habitats.
  • The authors assert that the use of artificial bat roosts can improve the dispersal of seeds into disturbed areas in need of forest restoration.
