Eurycoma Longifolia Jack

Eurycoma longifolia (EL) is a species that have economical benefit as medicinal ingredients for human health. This species grows in tropical forest areas with high rainfall. Research on the ecology of EL has been done a lot, but research related to ethnotaxonomic, bioecology that includes morphology, ecology, and the association of EL with other plants hasn’t been done much. This study aim to analyze the bioecology of EL plant. The method is literature study, which is looking for literature on the results of research that has been carried out related to EL. The results showed that EL has long been known by the communities of Indonesia and other countries in Southeast Asia with several local names. This plant is also associated with other plants around where it grows, one of which is kempas (Koompassia malaccensis). Based on the results of literature review, research on natural regeneration of EL hasn’t been done much. Therefore, there is a need for research related to the natural regeneration of EL. In addition, it is necessary to conduct research related to the characteristics of the place to grow for optimal cultivation of EL. Thus, the preservation of EL in the future can be maintained.

The Impact

Total aboveground carbon (TAC) and total soil carbon stock in the agroforestry system at the Balung River Plantation, Sabah, Malaysia were investigated to scientifically support the sustaining of natural forest for mitigating global warming via reducing carbon in the atmosphere. Agroforestry, monoculture, and natural tropical forests were investigated to calculate the carbon stock and sequestration based on three different combinations of oil palm and agarwood in agroforestry systems from 2014 to 2018. These combinations were oil palm (27 years) and agarwood (seven years), oil palm (20 years) and agarwood (seven years), and oil palm (17 years) and agarwood (five years). Monoculture oil palm (16 years), oil palm (six years), and natural tropical forest were set as the control. Three randomly selected plots for agroforestry and monoculture plantation were 0.25 ha (50 × 50 m), respectively, whereas for the natural tropical forest it was 0.09 ha (30 × 30 m). A nondestructive sampling method followed by the allometric equation determined the standing biomass. Organic and shrub layers collected in a square frame (1 × 1 m) were analyzed using the CHN628 series (LECO Corp., MI, USA) for carbon content. Soil bulk density of randomly selected points within the three different layers, that is, 0 to 5, 5 to 10, and 10 to 30 cm were used to determine the total ecosystem carbon (TEC) stock in each agroforestry system which was 79.13, 85.40, and 78.28 Mg C ha−1, respectively. The TEC in the monoculture oil palm was 76.44 and 60.30 Mg C ha−1, whereas natural tropical forest had the highest TEC of 287.29 Mg C ha−1. The forest stand had the highest TEC capacity as compared with the agroforestry and monoculture systems. The impact of planting systems on the TEC showed a statistically significant difference at a 95% confidence interval for the various carbon pools among the agroforestry, monoculture, and natural tropical forests. Therefore, the forest must be sustained because of its higher capacity to store carbon in mitigating global warming.

Abstract Key message: The Enrichment Plantation of Akure Forest Reserve is one of the forests currently experiencing a 17-year-long post-disturbance following deforestation and fragmentation in Nigeria. Context: To better understand the contribution of enrichment planting on forest regeneration and restoration, when the Enrichment Plantation after 17 years of post-disturbance was examined. Aims: We studied the recruitment drive of aboveground and undergrowth stands of an Enrichment Plantation in the tropical forest reserve. We assess the trees diversity, species compositions, species richness, and growth forms of the vegetations. Methods: A total of 3(50m x50m) plots were sampled. A total of 47 aboveground tree species and 45 undergrowth stands from Enrichment Plantation were identified. A statistical analysis were used to quantified the data obtained from this resultsResults: The result shows an increase in the diversity and an even distribution of the species of the aboveground forest trees, compared to the undergrowth stands. Conversely, the aboveground forest trees have lower species richness as compared to the level of undergrowth stands. The sapling density was significantly higher than the aboveground tree of the. It was also observed that the aboveground forest trees and undergrowth stands are somewhat similar in species compositions, which implies that sapling recruitment is a key determinant of the tree species composition of the forest.Conclusion: It is then concluded that the method adopted for restoration encouraged species diversity in this successional forest among the aboveground trees species and undergrowth.

The climate change and carbon mitigation through forest ecosystems play an important role in the global perspective. Soil is a huge carbon reservoir and its storage capacity varied greatly with forest type and altitude. The mountain ecosystem varies in soil organic carbon stock (SOC) due to variations in soil types, climatic conditions, vegetation patterns and elevational gradients. Soil organic carbon stockswere measured at three depths (0–10, 10–20, and 20–30 cm) in five different forest elevation (200, 400, 600, 800, and 1000 m asl) on Courtallam hills, Southern Western Ghats, India. SOC stocks increased significantly with the increase in altitude (P<0.05) at all the three layers (0–10, 10–20 and 20–30 cm). A total of SOC stocks ranged from 42.79 mg ha-1at 0–30 cm depth were observed in lower altitude (200 m) and the highest value of 50.25 mg ha-1 at 0–30 cm depth was observed in mid-elevation 600 m, while in other elevational showed 46.45, 48.49 and 45.05 mg ha-1 in 400, 800 and 1000 m respectively. SOC ranged from 17.89 to 22.37 mg ha-1 in soil surface layer (0–10 cm), 14.00 to 16.573 mg ha-1 in middle layer (10–20 cm) and 9.08 to 11.35 mg ha-1 in the bottom layer (20–30 cm). These results would also enhance our ability to assesses the role of these forest types in soil carbon sequestration and for developing and validating the SOC models for tropical forest ecosystems.

The pattern of soil carbon stock is atypical along the slope position in a seasonally dry tropical forest; the mean stock values increase from the lower, middle, to upper slopes, at 11.5, 13.2, and 15.5 kg m−2, respectively. In sloping landscapes, soil organic carbon tends to accumulate in lower slopes, but our previous soil respiration study suggested that soil carbon stock distribution along the slope position in seasonally dry tropical forests is atypical. The aims of this study were: (i) to examine whether the atypical pattern occurs widely in the watershed; and (ii) to examine the pattern of root development in the soil profile as a source of soil carbon. The density and stock of soil carbon in three soil layers (0–10, 10–30, and 30–100 cm) of 13 soil profiles were compared in different positions on the slope (upper, middle, and lower). Root biomass at each slope position was also determined. Soil carbon density in each layer increased significantly with an increase in the relative position of the slopes, particularly in the 10–30 cm soil layer. The density of medium root (3–10 mm in diameter) in the upper slopes was significantly higher than that in the middle and lower slopes, especially for 15–60 cm soil layers. The atypical pattern of soil carbon accumulation along the slope position occurred widely in the studied watershed and appeared to be caused by the development of root systems in deeply weathered soil under xeric soil conditions in the upper slopes. Roots of bamboo undergrowth may also contribute to soil carbon stabilization by reducing soil erosion in the surface soil.
