The biophysical environment is an important determinant of land degradation in both commercial and communal land tenure systems in South Africa. According to a recent study on the status of land degradation, approximately 25% of the total land cover in South Africa is degraded. Several technologies exist to restore the soil and vegetation degraded areas in natural pastures. To improve the produ...

Encroachment of tall grasses and shrubs in coastal dunes has resulted in loss of vegetation heterogeneity. This is expected to have negative effects on animal diversity. To counteract encroachment and develop structural heterogeneity grazing is a widely used management practice. Here, we aim to functionally interpret changes in vegetation composition and configuration following grazing manageme...

Arid and semi-arid lands constitute a large proportion of available agricultural and rangeland in the world. These lands are characterised by low and unreliable rainfall, low land productivity, and low socioeconomic status of the inhabitants. Livestock plays a very significant role in their economies. Leguminous trees and shrubs, which dominate the natural rangelands, are often higher in crude ...

Abstract The article describes the expansion within Khentei-Chikoy Highlands (Eastern Siberia and North-Eastern Mongolia) of range a rare bird species, Chinese bush warbler ( Locustella tacsanowskia (Swinhoe, 1871)). Based on results long-term observations, characteristics habitats this species are given. It is shown that Siberian pied beetle has fairly wide distribution in territory both fores...

Abstract Aims Grassland-to-shrubland transition is a common form of land degradation in drylands worldwide. It often attributed to changes disturbance regimes, particularly overgrazing. A myriad direct and indirect effects (e.g., accelerated soil erosion) grazing may favor shrubs over grasses, but their relative importance unclear. We tested the hypothesis that topsoil “winnowing” by wind erosi...

YiJinHuoLuo Banner is a county of Inner Mongolia with obvious semiarid monsoon climate. Because of unsuitable land use, such as cultivating marginal land and over pasture, desertification was getting severer and severer before 1974. Since 1974, People have been doing their best to grow woods, shrubs and grasses for increasing the coverage of vegetation. People have taken suitable and available ...

Ionic stress is one of the most important components of salinity and is brought about by excess Na+ accumulation, especially in the aerial parts of plants. Since Na+ interferes with K+ homeostasis, and especially given its involvement in numerous metabolic processes, maintaining a balanced cytosolic Na+/K+ ratio has become a key salinity tolerance mechanism. Achieving this homeostatic balance r...
