Full Project Title: 
Optimising tree systems for rehabilitation of degraded land
Project Summary: 

There is much interest in designing tree systems that restore degraded landscapes, sequester carbon, improve soil fertility and provide other ecosystem services. Fast-growing exotic trees in monoculture are often favoured over native, multispecies tree plantations and secondary forests. We study plantation design and forests for best outcomes including productivity, soil fertility and carbon sequestration. Ecological questions on niche differentiation and complementarity are addressed with empirical research and modeling. This project links researchers in Australia, Vietnam and Brazil. Current research is examining soil biology to determine impediments to forest establishment.

Funding Sources: 

This project is funded through the German Agency for International Cooperation (GIZ) and Australian Centre of International Agriculture Research (ACIAR).
