“…Te dominance range (15.0-20.6 m 2 •ha −1 ) in this study was well comparable to the value reported for the human-disturbed forest (17.77-24.47 m 2 •ha −1 ) in the Popa Mountain Park [27]. However, it was much lower than those recorded in the Alaungdaw Kathapa National Park (60.03 m 2 •ha −1 ) [25] and the Natmataung National Park (55.63 m 2 •ha −1 ) [65], which have been protected since 1984 and 1994 in upper Myanmar.…”

The Zalon Taung National Park (ZNP) in Banmauk township, northwest Myanmar, is a recently established protected area to protect the area’s cultural value, ecosystems, native flora, and wildlife. This research examined the vegetation structure, tree species diversity, and composition within (ZNP) and outside (the Banmauk unclassified forest (BUCF)) the park to inform conservation and resource utilization for sustainable management. We conducted the vegetation survey in April-May of 2022 by setting up 34 sample plots (40 × 40 meters) using a random sampling approach. We used stand density, basal area, Shannon–Wiener diversity index, Simpson index, Pielou's evenness, Fisher’s α diversity, and Importance Value Index (IVI) to determine the forest structure and tree diversity. A total of 116 tree species (≥10 cm·dbh), representing 87 genera and 48 families, were identified. The ZNP sample plots had a slightly higher stand density (201 individuals ha−1) and basal area (20.6 m2·ha−1) than BUCF (stand density: 191 individuals ha−1 and basal area: 15.0 m2·ha−1), which is accessible to collect firewood and timber extraction by residents. The reverse J-shaped pattern of the population structure indicated that the stands’ populations were progressive and healthy. BUCF featured the most Verbenaceae (12.9%) and the ZNP the most Euphorbiaceae (7.2%) families. Protium serratum had the highest IVI in the BUCF (26.91%) and Dipterocarpus alatus (18.39%) in the ZNP. Dipterocarpus alatus and Dalbergia oliveri (IUCN Red List-endangered species) dominate in BUCF and require special attention in conservation planning. In the ZNP, previous logging activity dramatically reduced the relative density and the IVI values of commercially important species such as Tectona grandis, Dalbergia oliveri, and Protium serratum. According to the NMDS ordination, differences in tree species compositions were significantly linked with elevation, the intensity of logging, and distance to the village and road. The results will help park managers plan effective land use to promote biodiversity conservation and local livelihoods.

“…Our study showed that the ZNP requires efective conservation compared to species richness in other protected areas in Myanmar [25,26,65]. However, the proximity of the sample plots to human-dominated areas may explain the restricted diversity of the species.…”

“…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.
