Stratified vegetation cover index: A new way to assess vegetation impact on soil erosion

Catena, 2010
Vegetation cover is an important parameter used in assessing the relationship between vegetation and soil erosion However, the intensity of soil erosion actually changes not only with vegetation cover but also with differences in vegetation type and ...

Simulation of vegetation cover on sidewalks in Denmark

Pest Management Science, 2004
Abstract Data from five 3‐year experiments comparing different strategies of non‐chemical weed control were analysed in order to set up a model that could be used for simulating further strategies. The treatments included different frequencies and effects of weed control using flaming, steaming and weed brushing.

Vegetation and Land Cover

2018
Four main factors, namely climatic situation, phytogeographical regions, varied topography , and the impact of human activity are considered responsible for the changes in distribution and character of the natural vegetation. The extensive Iranian plateau displays quite a variation in such a way that 167 families of vascular plants and 1215 genera ...

Transformed difference vegetation index (TDVI) for vegetation cover mapping

IEEE International Geoscience and Remote Sensing Symposium, 2003
In this study, we present a new vegetation index, the TDVI: transformed difference vegetation index. This index shows the same sensitivity as the soil adjusted vegetation index (SAVI) to the optical proprieties of bare soil subjacent to the cover. It does not saturate like NDVI and SAVI and it shows an excellent linearity as a function of the rate of ...

Vegetation cover and occurrence of salamanders in the western Mediterranean

Integrative Zoology, 2021
AbstractThe Mediterranean region possesses a rich diversity of salamanders, which also exhibit a high degree of ecological diversification. It is assumed that the presence of salamanders is dependent on the level of vegetation cover in terrestrial habitats, but the strength of this association is likely to vary among species.

Vegetative Covers for Waste Containment

2003
Disposal of municipal and hazardous waste in the United States is primarily accomplished by containment in lined and capped landfills. Evapotranspiration cover systems offer an alternative to conventional landfill cap systems. These covers work on completely different principles than traditional covers do, and that difference may slow understanding and

Relationships between percent vegetation cover and vegetation indices

International Journal of Remote Sensing, 1998
In this paper, percent vegetation cover is estimated from vegetation indices using simulated Advanced Very High Resolution Radiometer (AVHRR) data derived from in situ spectral reflectance data. Spectral reflectance measurements were conducted on grasslands in Mongolia and Japan.

Vegetation Cover of Porphyry Outcrops

1996
The plant cover of the porphyry landscape northwest of Halle forms a mosaic of strongly contrasting vegetation units. These are characterized by a high species diversity and the presence of a high number of species rare for this region. Reasons for the high species number and diversity are site dependant changes in edaphic and microclimatic factors ...

Vegetation Cover Monitoring

2003
The plant cover of the Nizhne-Koshelevsky hydrothermal field area (Southern Kamchatka) was studied 20 years after being damaged by prospecting and exploratory drilling. Siberian dwarf-pine and dwarf-alder elfin woods were replaced by secondary herb- and grass communities.
