the overgrazing and excessive utilization of rangelands has caused vegetationand soil degradation in many rangelands. in the rangeland management, the soil andvegetation elements, environmental factors and livestock should be considered as decisionmaking agents. various methods are applicable for the rangeland restoration as contourfurrows and mortar stone dam. in order to evaluate the effects ...

infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. the most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. in present study, through...

Understanding the interactions among invasive species, native species and marine protected areas (MPAs), long-term regime shifts in MPAs is receiving increased attention, since biological invasions can alter structure functioning of ecosystems challenge conservation efforts. Here we found evidence marked modifications rocky reef associated biota a Mediterranean MPA from 2009 to 2019 through vis...

ABSTRACT The phenomenon of desertification has a negative impact on the national economy any country and may usually be obtained for many reasons such as removal agricultural land, depletion soil, overgrazing, methods poor irrigation, high temperature, lack rainfall. following paper tackles solving problem rainfall through use chemical preparing sodium polyacrylate improving its properties by m...

Overgrazing and grassland degradation are significant environmental problems in the mountain ecosystems of Central Caucasus. The aim was to define criteria for stages provide land managers with useful guidelines on evaluating status. We identified four based a statistical analysis 23 vegetation soil parameters at 126 model plots subalpine meadows. Main indicators were grass height, coverage for...

Grassland farms form the basis of grassland resource management in China. Farm sizes China are generally small, which obviously increases risk ecosystems. It is necessary to analyze impact farm size on grasslands from perspective livestock production order improve management. This study combines field investigations and statistical analysis 2004 2020, using a total 126 Xilinguole League Inner M...

Impacts of livestock grazing in arid and semiarid environments are often concentrated in and around wetlands where animals congregate for water, cooler temperatures, and green forage. We assessed the impacts of winter-spring (November-May) cattle grazing on marsh vegetation cover and occupancy of a highly secretive marsh bird that relies on dense vegetation cover, the California Black Rail (Lat...

In the Mediterranean Sea hard-bottom macroalgal meadows may switch to alternative and less-productive barrens grounds, as a result of sea urchins overgrazing. Meiofauna (and especially nematodes) represent key components of benthic ecosystems, are highly-diversified, sensitive to environmental change and anthropogenic impacts, but, so-far, have been neglected in studies on regime shifts. We rep...
