Partner: ICRAF and Baoshan Forestry Department
Duration: 2005 May to 2007 April

Objectives:

• Experiment with different models for improving monoculture forest stand areas.
• Select suitable trees for diversifying conifer forest areas.
• Extend successful models to different areas.

Methods:

• Initial assessment of sample plots.
• Improvement of forest composition through thinning, with a random distribution. Each plot will be one mu, and have three replicates with 15 treatments. A control plot will be designated in the same forest area.
• Strip thinning, using 8-meter wide strips with 30 meters between strips. Holes of 40กม40กม40cm will be dug with a plant and row spacing of 2กม3m.
• Planting of broad-leaf tree species in open clearings. Ten species of trees will be used. Each plot will be one mu, using three replicates with 16 treatments. A control plot will be designated in the same forest area.

Outputs:

• Comparison of research results.
• Evaluation of results for different plots.
•  Selection of suitable cutting methods.
• Methods for improving and diversifying monoculture coniferous forest areas.
