Dec 01, 2005· 1. Introduction. Predicting impacts of limestone quarrying activity on adjacent wetlands is a highly uncertain process, for at least two reasons: (i) the heterogeneity of hydrological processes in many limestone terrains ( Smart et al., 1991), and (ii) the inherent difficulty in distinguishing between the sensitivity of plant communities to change in water table conditions and water ...
Reclamation of limestone quarries around the world is challenged by an extremely limiting environment, including steep slopes, scarce topsoil and high calcium carbonate substrates with low nutrients and water holding capacity. These issues were addressed at a limestone quarry in the Rocky Mountains of southern Alberta. Reintroduction of key components, such as vegetation and ameliorated soil ...
a limestone quarry of Malá dohoda which is located in a protected landscape area in the northern part of Moravian Karst. Using formaldehyde pitfall traps, 1682 specimens belonging to 66 species were caught in 2012, out of which 847 specimens (49 species) were from the active quarry of Malá
Habitat restoration projects are often conducted when prior use or extraction of natural resources results in land degradation. The success of restoration programmes, however, is variable, and studies that provide evidence of long term outcomes are valuable for evaluation purposes. This study focused on the restoration of vegetation within a limestone quarry in Dorset, UK between 1997 and 2014.
May 03, 2018· Indigenous animals, insects, and tress all struggle to survive when a limestone quarry is established. Digging into the ground to remove this natural resource skews the balance of the ecosystem in a way that can make it difficult for many local species to survive. 4. Quarries may have a negative health impact.
a limestone quarry (Limeira quarry), located at Ribeirão Grande municipality (SP), southeastern Brazil. Species were captured with pitfall and Sherman traps along eight pairs of 60 m transects distributed at four different distances from the quarry (60, 220, 740 and 1300 m). Between October 2005 and January 2008, 20 small mammal
Spider communities are sensitive to a wide range of environmental factors and are potential ecological indicators which may be effective in the assessment and monitoring of restored ecosystems. One restoration technique of disused limestone quarry faces, landform replication, attempts to create landforms and ecosystems similar to those found on natural dalesides.
Apr 03, 2019· Species composition strongly depends on time, place and resources. In this context, seminatural grasslands belong to the most speciesrich habitats of Europe, and succession may eventually cause ...
Nov 20, 2017· The Philippines is both a megadiversity country and a global biodiversity hotspot. The diversity patterns of three major plant groups were assessed: (1) trees (trees and palms), (2) herbs (grasses, shrubs, forbs, ferns), and (3) epiphytes (climbers and epiphytes), by determining the changes in compositional and species richness patterns in two forest conditions,, remnant forests and ...
Limestone is an important raw material that is widely used for multiple agricultural and industrial purposes (Pamukcu, and Simsir, 2006). Rapid economic development and the growth of urban areas in many countries have increased need for limestone which, in turn, created many abandoned quarrying sites in urban areas offering unique challenges to urban agency managers such as foresters, and ...
Evaluating the impact of a limestone quarry on suspended and accumulated dust Article (PDF Available) in Atmospheric Environment 45(9): · .
Jan 14, 2009· Bee species are also of conservation concern and have been recorded frequently in limestone quarries (Westrich 1989, 1990). In this study, we analysed the relative influence of habitat area, habitat age, and within‐habitat diversity for wild bee species richness, abundance and community composition in limestone quarries.
Open pit mining is a common activity in the Yucatan peninsula for the extraction of limestone. This mining is known under the generic name of quarries, and regionally as sascaberas (sascab=white soil in Mayan language). These areas are characterized by the total removal of the natural vegetation cover and soil in order to have access to the calcareous material.
Species composition of the vegetation of several sites (worked; unworked; spoil heap in the quarry and its environs) in a cement manufacturing town, Sagamu, Southwestern Nigeria, was studied. The aim was to document the plant species compostition (biodiversity) of the quarry sites and its environs, which will provide baseline data for assessing the impact of limestone quarrying on the ...
Dec 18, 2014· Limestone quarrying is "the primary threat to the survival of karstassociated species, and it will certainly exacerbate the biodiversity crisis in Southeast Asia," the study said.
Limestone mountains have strategic functions as limestone is used as building materials and as raw material in cement industry. Therefore, limestone mining quarry in various areas of limestone mountains in Indonesia is increasingly widespread. The biggest negative impact of limestone mining is the formed open land which is abandoned and unutilized.
Mar 01, 2011· The Kefar Gil''adi quarry is located in the northwest Hula valley (), on the eastern slopes of the Upper Galilee area (Israel).The quarry''s main interest is the 200m thick layer of Middle Eocene "Bar Kokhba" Formation limestone rock, underlying the "Kefar Gil''adi" Formation, a 400m thick sequence of Neogene conglomerates, limestone, and clays (Sneh and Weinberger, 2003).
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being limesecreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...
Aug 02, 2017· Rock climbing is among the outdoor activities that have undergone the highest growth since the second half of the 20th century. As a result, cliff habitats, historically one of the least disturbed by human colonization worldwide, are facing more intense human pressure than ever before. However, there is little data on the impact of this activity in plantcommunities, and such information is ...
Spontaneous vegetation dynamics and restoration prospects for limestone quarries in Lebanon. Carla Khater. ... Correspondence analyses were used to pinpoint similarities in the distribution of key species among the different environmental characteristics of sites. The main results reveal a heterogeneous floristic composition along the ...
