Observations of wild boar damage to alpine grazing pastures in Romania's Carpathian Mountains were collected using photographs of the slopes from vantage points. We mapped the rooted areas and then used GIS software to estimate the relative proportions of the total grazing areas visible in the photographs that were damaged by wild boar. The amounts of damage from our two demonstration pastures ...

introduction:changes caused by grazing on range ecosystem are generally assessed based on the soil conditions and vegetation. livestock as one of the major elements in range land ecosystems has different effects on different parts of this ecosystem. one of these impacts is excessive livestock grazing capacity which can have different effects on soils and plants in various intensities. materials...

The effect of cattle grazing on the soil nematode and protozoan communities, and on microbial biomass, was measured in Israel’s northern highlands. Three grazing areas were compared: (1) with 1 1 cow ha 1 y ; (2) 0 55 cow ha 1 y ; and (3) control—no grazing for almost 18 years. Soil samples were collected from the upper 10 cm level of each area (n1⁄4 24), in autumn, before the onset of the rain...

Three grass species, Agropyron desertorum (Agde) and Agropyron elongatum (Agel) and recently, Bromus tomentellus (Brto) are mainly used for range improvement as mixed seeding in semi-arid areas of Iran. Because there is little information about management of these grasses, this study was conducted at the Sisab Research Station in northern Iran to evaluate their responses to grazing management a...

     Forage production of rangelands differs during different times of grazing season and in the same month of different years. In range management projects, grazing capacity calculated once during the grazing season, which coincides with the maximum production of rangeland species. This may cause more livestock entry into the rangeland during the grazing season, leading to more degradation. Th...

Grazing by large herbivores may negatively affect bird populations. This is of great conservation concern in areas with intensive sheep grazing. Sheep management varies substantially between regions, but no study has been performed in less intensively grazed systems. In a fully replicated, landscape scale experiment with three levels of sheep grazing, we tested whether the abundance and diversi...

We evaluated the effects of livestock grazing on C content of the plant-soil system (to 60 cm) of two semi-arid grasslands: a mixed-grass prairie (grazed 12 years), and a short-grass steppe (grazed 56 years). Grazing treatments included season-long grazing at heavy and light stocking rates, and non-grazed exclosures. Significantly higher soil C (0-30cm) was measured in grazed pastures compared ...
