With the introduced close-to-nature management philosophy and technology, the artificial mixed experimental forest, can create microclimate conditions and promote the natural regeneration of fine tree species either by dispersing the forest gap with the high-intensity thinning of the stands, or by planting the suitable precious timber species under the canopy, to promote the transformation from the single-storied stand into the uneven-aged stratified mixed stand with multiple species and multiple layers. When adjusting the stand structure, full consideration is given to the growth of the upper forest and the natural regeneration capacity of the tree species or the surrounding forest tree species to create the optimal stand conditions and maximize the natural regeneration ability of the tree species. For the stand with poor natural regeneration ability that does not have natural regeneration source of seedlings in the surrounding areas, replanting of precious timber species under canopy is carried out to promote the stand to grow up to a multi-layer forest as soon as possible.

After nearly 30 years of technological transformation, the experimental area has formed a high quality and high efficient patchy artificial mixed forest consisting of multiple tree species. Forest biodiversity and landscape diversity have been increased, and the stability of the forest further strengthened. The forest is rich in tree species, well-structured and beautifully landscaped with good forest recreation effect. (Experimental Center of Tropical Forestry)
