Natural Dynamics

Modern aeolian relief is widespread in the forest-steppe landscapes of Transbaikalia. Valleys of the Selenga River and its inflows are the areas covered by ancient sandy deposits. Human impact in dry climatic conditions causes intensive wind erosion and formation of open and moving sands covered with sparse plants. The flora and vegetation of such landscapes notably differ from surrounding territories. It’s particularity is caused by presence and domination of plant species usually seen on open sands. Despite of numerous publications describing the sandy dunes of Transbaikalia, the psammophyte vegetation and natural dynamics of sandy landscapes are poorly documented. This study presents the analysis of 398 relevés describing psammophyte vegetation from the South-West Transbaikalia (Selenginsky, Dzhidinsky, Kyakhtinsky and Bichursky administrative disticts of the Republic of Buryatia).

Soil Flux

In an on-station agroforestry experiment conducted in south-west Niger, the effects of seven windbreak species and of a soil mulch made from crop residue on wind erosion and pearl millet (Pennisetum glaucum) production were monitored. Within a distance of 20 m, strips of the perennial grass, Andropogon gayanus, reduced total annual soil flux by 6–55% and hedges of Bauhinia rufescens 2 m in height reduced soil flux by 47–77% compared with unsheltered control plots. No significant overall windbreak effect on millet stover and grain yields was found. In contrast, erosion reduction and yield increases due to mulch application were highly significant. Soil mulch is a promising alternative to complex windbreak–millet cropping systems in regions where direct economic benefits for farmers are not ensured by windbreaks.
