Ecology: Experiment on tree species diversity in a tropical forest

Logged Dipterocarp forests are being replanted with three levels of tree species diversity for the purpose of investigating how forest diversity affects wood production, carbon storage and other ecosystem processes in tropical regions.

The replanting is being carried out using monocultures, low-diversity mixtures similar to those in commercial reforestation areas and using a full mixture of species reflecting the natural diversity of the primary forest.

The aim of the project is to compare community and ecosystem processes in low and in high species diversity plots.

The focus of the analysis is on diversity and wood production (carbon sequestration), biogeochemical and hydrological variables, and levels of biodiversity.



The field research is being carried out at a state-owned research station of the provider country. Samples of tree litter will be collected for biomass quantification. No material, only data, are exported to Belgium (Flanders).



Genetic resource: Tree litter (leaves and twigs)

Access: In situ collection of plant material

Utilization: Weighing of plant biomass, spherical densiometer, measurements of canopy coverage

Stakeholders involved in ABS-procedures: (no ABS case)

Steps: Inquire about necessary research permits, export permits.

Notes: This research project doesn’t involve molecular or biochemical analyses of genetic resources and therefore it doesn’t fall under ABS regulations of the Nagoya Protocol. However, check the ABS requirements of the provider country.
