  • Seed survival was tested in 4 replicates each of three habitat types in montane Costa Rica: abandoned pasture (3 years since abandonment), secondary forest (8 years since abandonment), and fragments of primary forest.
  • Seeds of 7 native species were placed along three 50m transects at each site.
  • Some seeds had strings attached and some planted under wire-mesh rodent exclosures to test for germination.
  • Seed survival was around 65%.
  • After 12 weeks, the proportion of surviving seeds was significantly higher in secondary forest rather than abandoned pasture and primary forest.
  • Rodent predation was lower in the human-altered landscapes than in the primary forest fragments.
  • The authors suggest that a lack of seed dispersal may be a more important barrier to natural regeneration than predation.
