Soendjoto MA, Riefani MK, Triwibowo D, Metasari D. 2018. Birds observed during the monitoring period of 2013-2017 in the revegetation area of ex-coal mining sites in South Kalimantan, Indonesia. Biodiversitas 19: 323-329. The number of bird species in the reclaimed and revegetated ex-mine site increases as the vegetation age increases. To test the hypotheses, the number of bird species was recorded at 08.00-12.00 and 14.00-17.00, 6-8 days for eight consecutive semiannual monitorings of 2013-2017 in four revegetation sites. Since the second half of 2015, another revegetation site, namely BP was added. Bird species were recorded in 25 m right side and 25 m left side of the observation path and within a radius of 25 m of observation points. To show an increase in the number of bird species, the number of newly discovered bird species in the given semiannual monitoring was added to the number of bird species in the previous semiannual monitoring. The number of bird species in the early semiannual monitoring was used as the baseline value. A bird species was categorized as a resident if the species was observed in each monitoring in the four vegetated sites. Up to the last monitoring, 53 bird species were recorded in the first four sites and 70 bird species in five sites (four reclamation and revegetation sites and one additional site, BP), while in the early semiannual monitoring (second half of 2013) birds recorded were only 30 species. This result shows that the older the vegetation age in the vegetated site, the greater the number of bird species utilizing the site. Seventeen species of birds were categorized as residents. These resident bird species includes White-breasted Woodswallow, Pied Triller, Scalybreasted Munia, Asian House-martin, Pacific Swallow, Long-tailed Shrike, Blue-throated Bee-eater, Olive-backed Sunbird, Sootyheaded Bulbul, Yellow-vented Bulbul, White-breasted Waterhen, Ashy Tailorbird, Yellow-bellied Prinia.

Balochistan is a semi-arid region. The assessment of water quality is very important, as the majority of people depend on groundwater for drinking purposes. The present study involves the quality assessment and mapping of drinking water in the five selected major coal mining sites in the four districts of Balochistan. A total of 50 samples were collected from these five coal mining sites in two seasons: i.e., summer and winter. A physicochemical analysis was carried out for groundwater samples: i.e., pH, electrical conductivity (EC), total dissolved solid (TDS), CO3, HCO3-, Cl-, Ca2+, Mg2+, Na+, K+, Cd, Cr, Co, Cu, Fe, Pb, Mn, Hg, Ni, and Zn. Thematic maps were used to depict the spatial distribution of significant variables and were compared with WHO standards (2011) during both seasons. The majority of parameters crossed the safe permissible limit of WHO standards. The water quality index (WQI) was calculated for the whole monitoring data obtained from both seasons from the perspective of drinking water in each of the selected sites. Moreover, a principle component analysis (PCA) and correlation matrix was carried out for the data analysis in order to identify the source of pollution and correlation among the variables. The results suggested that the overall quality of water from the selected coal mining sites deteriorated due to the overexploitation of coal mines and mining activity. The current investigation provides a comprehensive picture of the current status of water quality in and around the selected coal mines of Balochistan.

In subtropical regions like the Chaco Serrano (33° S), rainfall has a marked seasonality, and water flood, caused by heavy rains, may have important consequences for dependent ecosystems. Conversely, the high pressure on available resources during dry periods can also affect the fauna diversity and distribution. Even though birds have shown to be excellent ecological indicators of these shifts in the environment, currently little is known about the avifauna of the Argentine Chaco Serrano phytogeographic district. Our aim was to study the resident bird population status in the Southern Chaco Serrano, its fluctuations in richness and abundance, and its relationship to seasonal variations, in monthly and annual hydroperiods. In order to assess the resident bird status over a two year period (2011 Mar.-2013 Feb.) we carried out 18 sampling surveys during pre-breeding (spring), breeding (summer) and non breeding periods (autumn-winter), in the Northeastern part of the Valle Fértil Natural Park, San Juan province, Argentina. During each site survey, we recorded bird assemblages found in six transects, and obtained bird abundance and species diversity. A mixed general linear model was employed to evaluate relationships between the studied variables. We found a total of 98 species of birds belonging to 33 families (44 resident species, 23 spring visitors, six summer visitors, two winter visitors and 23 with scarce registers). We also registered 68 of these species in both hydroperiods, 28 only during rainy periods and only two during the dry period. Both richness and abundance showed the highest values during the pre-breeding and rainy seasons, while different tendencies were detected during the isolated monthly rainfalls. These changes in bird densities were associated with the arrival of migratory species, mainly spring visitors, and probably in relationship with their reproductive activity, and to seasonal fluctuations in food resources. The Southern Chaco Serrano is a subtropical semiarid place that seems to be an important breeding habitat for many migrant bird species, which in turn promoted seasonal changes in species density and diversity, mainly during rainy years. This work contributed to our understanding on the causes of richness and abundance variations on birds, and will contribute to this important group management and conservation in this area.

A bird survey was carried out on one of Nepal’s most popular trekking destinations, Annapurna Base Camp in the Annapurna Conservation Area (ACA). ACA trekking route was selected as our transect line. Direct observation method and call count method were used during the survey following the transect line. A total of 166 species were recorded representing nine orders and 39 families. The main objective of the present work was to study the avian diversity. Eight nationally threatened and three globally threatened bird species were recorded during the survey. White-rumped vulture Gyps bengalensis (Gmelin) and Red-headed vulture Sarcogyps calvus (Scopoli) (critically endangered species) were also recorded. The abundancy of Rufous sibia Malacias capistratus (Vigors) was higher, while Nepal house martin Delichon nipalense (Moore) had the highest number. Hunting, excessive harvesting of bamboo shoots, orchids, overgrazing and improper management of solid waste were directly observed threats.

This study aims to determine the history of the Ombilin Sawahlunto coal mine, the use of this site as a historical learning resource based on outdor learning and the obstacles it faces in its utilization. The method used in this research is qualitative with a descriptive approach. The sources used were interviews, literature and newspapers. After collecting the sources and separating the primary and secondary sources, rewrite them. The research results found that government projects in the city of sawahlunto consist of three projects including first, exploitation of coal mines, second, construction of railways, third, construction of the port of Emmahaven (Teluk Bayur). Traces of Dutch heritage that still exist today are the railway museum, Goedang Ranseum, Mbah Soero Mine Hole, and the Coal Mining Museum. This legacy can be used as a source of historical learning based on outdor learning.

Future carbon management during energy production will rely on carbon capture and sequestration technology and carbon sequestration methods for offsetting non-capturable losses. The present study quantifies carbon sequestration via reforestation using measurements and modeling for recent and legacy surface coal mining grasslands that are re-restored through tree planting. This paper focuses on a case study of legacy coal mining sites in the southern Appalachia the United States. This five million-hectare region has a surface mining footprint of approximately 12% of the land area, and the reclamation method was primarily grassland. The results of the soil carbon sequestration rates for restored forest soils approach 2.0 MgC ha−1 y−1 initially and average 1.0 MgC ha−1 y−1 for the first fifty years after reclamation. Plant, coarse root and litter carbon sequestration rates were 2.8 MgC ha−1 y−1 with plant carbon estimated to equilibrate to 110 MgC ha−1 after forty years. Plant, root and litter carbon stocks are projected to equilibrate at an order of magnitude greater carbon storage than the existing conditions, highlighting the net carbon gain. Reforestation of legacy mine sites shows carbon sequestration potential several orders of magnitude greater than typical land sequestration strategies for carbon offsets. Projections of future scenarios provide results that show the study region could be carbon neutral or a small sink if widespread reforesting during reclamation was implemented, which is contrary to the business-as-usual projections that result in a large amount of carbon being released to the atmosphere in this region.
