Getting trees on farms the easy way? Lessons from a model of eucalypt regeneration on pastures

Abstract

Substantial revegetation is required across much of Australian agricultural landscapes. Managers need to minimise the risks of failure and costs associated with revegetation. Whereas 'natural regeneration' of eucalypts is relatively cheap compared with direct seeding or planting tubes, natural regeneration in grazed lands occurs infrequently and under limited circumstances. Management needs to understand the situations in which natural regeneration is most likely to occur and what actions can improve the chances of regeneration. We used a rule- and stage-based model of eucalypt regeneration focusing on events between seed supply and sapling escape to synthesise current knowledge and learn ho..
