Central to this idea is to work with nature, after all our native plant ‘communities’ have already proved their success to be here through millennia of evolution.

A full description of this process is beyond the scope of this book but here is a brief overview. The first step is achieved by planting ‘pioneer’, fast growing trees, which can handle full sun and are generally short- lived in terms of a rainforest (10-30 years). Plant the pioneers 3-4m apart to form a canopy in 2-5 years depending on the site and conditions. Interspersed through these pioneer trees, ‘secondary’ and ‘mature phase’ trees are planted. These are slower to establish but can live for hundreds of years and in time will form the rainforest habitat. Once the canopy is established, the final staged planting will contain a diverse mix of trees, shrubs, vines and groundcovers. Where possible, try to source the species that grow naturally in your area – talk to your local native nursery and ensure you are also planting species with local population genetics. By planting in this manner, you will extend the existing habitat for local species encouraging them to move into the new areas that you have provided. Over time you will notice trees and other plants regenerating naturally. These are brought in by birds and the wind and germinate in the favourable conditions provided by the forest canopy. More information about planting a rainforest can be found in the book published by the Big Scrub Landcare Group Subtropical Rainforest Restoration. This book is essential for anyone looking at undertaking this process, providing a detailed overview of the many factors to consider, as well as a list of appropriate species to plant.
