Recreational Trampling of Vegetation: Standard Experimental Procedures

In order to promote an increased ability to compare results from different studies, a standard protocol for controlled trampling experiments is suggested. The procedure will provide information on both damage to vegetation in response to short-duration trampling and subsequent recovery over a one-year period. Changes in vegetation cover, vegetation height, bare ground cover, and the cover of in...

Simulated by a 3-D Transport Model: A Sensitivity Study to Vegetation and Soil Fractionation Factors

The l so /160 ratio in atmospheric CO~ is a signal dominated by the processes by which the global land biosphere absorbs and respires COs. Potentially it makes it possible to separate the photosynthesis from the total ecosystem respiration provided that leaf COs and soil COs have different isotopic signatures, that the air-sea exchange is correctly treated and that the isotopic value of anthrop...

Coincidences of climate extremes and anomalous vegetation responses: comparing tree ring patterns to simulated productivity

Climate extremes can trigger exceptional responses in terrestrial ecosystems, for instance by altering growth or mortality rates. Such effects are often manifested in reductions in net primary productivity (NPP). Investigating a Europe-wide network of annual radial tree growth records confirms this pattern: we find that 28 % of tree ring width (TRW) indices are below two standard deviations in ...

Integrating terrain and vegetation indices to estimate and identify the soil erosion risk Amoughin watershed, Ardabil

Soil erosion is one of the environmental problems that is a threat to natural resources, agriculture and the environment, and in this regard, assessing the temporal and spatial amount of soil erosion has an effective role in management, erosion control and watershed management. The main aim of this study was to estimate soil erosion in Amoqin watershed and its relationship with well-known veget...
