The project will assist decision-makers to more efficiently restore biodiversity to degraded rainforest landscapes by providing
new knowledge about the outcomes of lower-cost natural regeneration (including potential for minimum intervention management)
relative to higher-cost active reforestation (replanting) on post-agricultural land. The outcomes of this project will enable
planners to assess the costs, risks and benefits of different approaches to reforestation and choose the most appropriate
method for any particular ecological and economic context.
This project will:
1. Quantify the rate and pattern of development of vegetation during rainforest regrowth following cessation of agricultural
use, and how this compares with the outcomes of publicly-funded restoration by tree-planting.
2. Investigate, trial and promote emerging technologies for the acceleration and redirection of rainforest regrowth, to overcome
ecological barriers or thresholds that inhibit rainforest redevelopment.
3. Identify locations and situations where passive restoration (unassisted regrowth) is a preferable alternative to high-cost
active restoration (replanting).
This will help government agencies and landholders to better forecast outcomes resulting from passive regeneration over
defined time frames. This knowledge will also be useful to private enterprises interested in capitalising on emerging carbon
This work will be done on the Atherton Tablelands in the Wet Tropics.
