Naturally regrowing eucalypts is a challenge

摘要

Large areas of Australia's grazing lands now need restocking with native vegetation in order to restore the integrity of the landscape and recharge ecosystems. But while 'natural regeneration' of eucalypts is typically relatively cheap for farmers compared with direct seeding or planting tubes, research shows that natural regeneration is fickle and can involve some risk in the allocation of resources to it.
