Abstract EN
To develop rehabilitation planting techniques in tropical degraded forests, we investigated (1) basic soil characteristics and light conditions; (2) growth and survival of seven dipterocarp seedlings over 81 months; and (3) the effect of environmental factors on the survival of seedlings grown in three degraded vegetations (grassland, secondary forest, and logged forest) in Sarawak, Malaysia.
The soil was weakly acidic, and kaolin minerals dominated.
The amount of exchangeable bases in surface soils, soil temperature (>35°C), and relative light intensity were all highest in the grassland.
Seedling growth was also highest in the grassland, whereas many seedlings died there over 81 months.
Growth and survivability were very similar in secondary and logged forests.
The death of the seedlings in the grassland was attributable to an extremely high light intensity for all species.
In contrast, the seedling growth rate in all species was also enhanced by light intensity.
In conclusion, dipterocarp seedlings can be planted on highly degraded land such as grassland, although high light intensity limits their survival.
Planting under nurse trees such as regenerated pioneer trees may be an effective method to enhance seedling survival under open conditions such as grassland.
