Assessing the Potential of Enrichment Plantings in North Queensland, Australia to increase Timber Production within Tropical Forests and the Implication for Forest Management and Restoration
The alarming loss of tropical forests in the past decades has brought about an increased market demand for a wide range of hardwood species. Therefore, improving the productivity of tropical hardwood timber species from natural stands to meet this demand has become an important goal. In an effort to increase the productivity of tropical forests, enrichment planting of key high-value timber species has been undertaken in many tropical areas. However, there have been few systematic attempts to assess how effective enrichment planting programs have been. In particular, the performance of underplanted species and factors affecting survival and growth of underplants have not been fully understood, particularly long-term observation data in the field.
The aim of this study is to (1) determine the performance of underplanted species over the time; (2) identify how overwood affect survival and growth rate of underplants over the time; (3) detect long-term patterns of growth and composition of overwood and underplanted.
The study area is located in the Kuranda area and some locations on the Atherton in North Queensland, Australia. Eight hardwood species are investigated in this study namely Agathis robusta, Agathis palmerstonii, Flindersia brayleyana, Flindersia ifflaiana, Araucaria bidwillii, Flindersia bourjotiana, Cardwellia sublimis, and Araucaria cunninghamii. Most these species have been underplanted more than 50 years ago as part of enrichment planting experiments, established by the Queensland Department of Forestry.
- Long-term performance of underplanted species will be assessed
- Key important factors affecting survival and growth of underplanted species will be identified
- Long-term growth and change pattern of underplanted species and overwood will be detected.
Impacts: Findings from this study will be used to guide strategies for enhancing the yields of tropical forests by underplanting in logged-over stands and degraded forests.
