Fragmented forest faces bleak future

摘要

Many projects to save rainforest species are doomed, ecologists warned this week. Species marooned within surviving islands of trees may disappear, despite attempts to grow new forest to reconnect the fragments. A study of forest fragments in the Brazilian Amazon shows the importance of preserving large natural areas. But it is also a major blow to conservationists trying to mend the damage to habitats that are increasingly broken into small pieces by human invasions.
