“…Our finding that suitable areas for the species are not expected to be severely impacted by the negative effects of climate change bodes well for its future use in tree planting projects. While a growing body of knowledge on the sexual and asexual propagation and management of E. cyclocarpum exists (Rodríguez-Sahagún et al 2007;Laborde and Corrales-Ferrayola 2012;Ekamawanti et al 2013;Obando and Moya 2013), limited attention has thus far been given to the genetic quality of planting material. Ensuring that reproductive material of E. cyclocarpum used in tree planting efforts will survive, thrive, and establish viable and resilient populations in the long term requires (1) adequate planning to identify the seed sources that are best matched to the conditions of the planting site and (2) application of good seed collection protocols (Thomas et al 2014(Thomas et al , 2015a.…”

Genetic diversity of Enterolobium cyclocarpum in Colombian seasonally dry tropical forest: implications for conservation and restoration

Enterolobium cyclocarpum is a characteristic legume tree species of seasonally dry tropical forests (SDTFs) of Mesoamerica and northern South America typically used in silvopastoral and agroforestry systems. Remaining populations of E. cyclocarpum in Colombia are severely fragmented owing to the highly degraded state of SDTF in the country, posing threats to both their in situ persistence and their usefulness as seed sources for future planting efforts. We genotyped E. cyclocarpum populations at nine sampling sites across a latitudinal gradient of SDTF in Colombia by means of eight nSSR markers to elucidate the species diversity distribution in the country. Our data suggest that a deep divide seems to have existed between Caribbean and Andean populations of E. cyclocarpum in Colombian SDTF that may date back to the last glacial maximum (*21,000 BP), or longer. However, we only found evidence of genetic differentiation between trees from the southern Cauca River valley and populations at more northern locations. All the latter populations showed signs of admixture which may be the result of human-influenced

“…AMF application and fastgrowing legume species of Pongamia pinnata increased both nutrient contents of post-coal mine soil and iron absorption, which was mostly accumulated in the root system [41]. AMF Gigaspora margarita and E. cyclocarpum seedlings could tolerate Hg metal supply [160]. Colonization by AMF inoculant improved plant resistance to acidity and phytotoxic levels of aluminum in the soil ecosystem [161].…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

“…Agus et al [41] reported that fast-growing legume species of Pongamia pinnata and AM fungi application can not only increase nutrient contents of post-coal mining soil but also increases iron absorption, which is mostly accumulated in the root system. Arbuscular mycorrhizal fungi Gigaspora margarita and E. cyclocarpum seedlings can tolerate up to 375 µM Hg supply [42]. Root colonization by symbiotic AM fungi enhances plant resistance to acidity and phytotoxic levels of aluminum in the soil environment [43].…”

The purpose of this investigation was to examine the effects of native AM fungal inoculation on the growth of Gmelina arborea, Samanea saman, Falcataria moluccana, and Enterolobium cyclocarpum under nursery and post-opencast bauxite mining field conditions. Two native AM fungi, Rhizophagus clarus and Gigaspora decipiens, were inoculated into seeds of G. arborea, S. saman, F. moluccana, and E. cyclocarpum. The seeds were sown in post-bauxite mining soil and grown in the nursery for three months. Seeds without AM inoculation were used as the control treatment. The seedlings were transplanted into a post-opencast bauxite mining field and grown for 12 months. Arbuscular mycorrhizal fungal colonization and shoot and root dry weights were measured. Under nursery conditions, G. arborea inoculated with G. decipiens increased shoot and root dry weights by 1,431 and 359 %, respectively, while shoot dry weight of E. cyclorapum inoculated with R. clarus and G. decipiens increased by 510 and 220%, respectively, in comparison with control seedlings. Root dry weight of E. cyclorapum inoculated with R. clarus increased by 224%, in comparison with control seedlings. Shoot dry weight of E. cyclorapum inoculated with R. clarus increased by 90%, in comparison with seedlings inoculated by G. decipiens. Twelve months after transplanting into post-opencast field conditions, the shoot dry weight of F. moluccana inoculated with G. decipiens was higher than that of the control seedlings by 188%. Shoot dry weight of E. cyclorapum inoculated with R. clarus and G. decipiens increased by 198% and 149%, respectively, in comparison with control seedlings. Shoot dry weight of E. cyclorapum seedlings inoculated with R. clarus was higher by 20% than that of seedlings inoculated with G. decipiens. These results show that AM fungal inoculation promotes the growth of tropical tree species on post-opencast bauxite mining land.
