“…This can be done by planting pioneer or fast-growing exotic species found in the original forest in the degraded forest areas. This would help shorten the succession phase of plant community by increasing the species composition and biodiversity [4][5][6][7][8][9].…”

This study aimed to investigate the structure and composition of plant community to i) identify tree species that can colonize, grow, and form communities and ii) identify species under natural succession whose seedlings can be used in forest rehabilitation. Experimental plots of size 40 m × 40 m were established in 13-, 10-, and 5-year-old rehabilitation areas (13YRA, 10YRA, and 5YRA), where characterized as flatted, sloped, and benched areas, respectively. The survey found 24 genera, 12 families, and 25 species of plants. Plant species that were found in all plots were Zollingeria dongnaiensis Pierre., Pterocarpus macrocarpus Kurz., Albizia lebbek (L.) Benth., and Azadirachta indica A. Juss.) which can potentially grow well in several conditions of post-mining areas. The 13YRA plot had the most significant number of naturally regenerating species (11 species) as the area was next to a natural forest or buffer zone and had been under restoration for the most prolonged period. The community succession of the rehabilitation plots relative to the natural forest was relatively slow. Nonetheless, the pioneer species can help to improve the environmental factors to optimum levels for the natural succession of the plant community. This can also be useful while selecting pioneer species for restoring areas previously used for limestone mining and help reduce the time for succession in terms of increasing the species composition.

Establishment of exotic plantations is one of the most effective ways to induce natural regeneration for the restoration of degraded lands, as it has the potential to improve soil properties and creates favorable microclimates. This study aims to determine the effects of stand structure and composition as well as environmental factors under the canopies of three exotic plantations in northeastern Thailand on the regeneration of native species. For each plantation, we conducted three 10 m × 150 m transect lines with fifteen 10 m × 10 m subplots along a forest remnant gradient. The canonical correspondence analysis (CCA) was used to identify the environmental factors responsible for the differences in natural regeneration among these stands. Three exotic plantations had different stand structure in terms of number of tree species, basal area, and tree density but similar dominant native tree species. Across all stands, 74 native tree species, 60 genera, and 30 families were observed. Some physical and chemical properties in the topsoil were significantly different between species but similar among stands within a species. On the other hand, differences in environmental factors such as RLI were significant among species and stands within a species. The CCA ordination identified that the soil particles, soil pH, and light intensity were key factors influencing the native species composition, which could be categorized into three groups: drought-tolerant pioneer species; light-demanding pioneer species; and shade-tolerant climax species. However, most of the climax species were incapable of regenerating and maturing along the forest edge gradient to plantation stands. To accelerate the restoration process by converting these old exotic plantations to a dry evergreen forest, further research is required to determine the appropriate canopy management and/or dominant climax species for planting beneath their canopies.
