  • The aim of this study was to test, under field conditions, the response of runoff, soil erosion, nutrient, carbon losses, and heavy-metal transport to different plant covers, including aromatic and medicinal plants and native vegetation during two
  • hydrological years. The study area is located in a coastal area of the south-eastern part of the Iberian Peninsula at Almuñécar (Granada, SE Spain). The results support the recommendation of using plant covers with multiple purposes (aromatic–medicinal–culinary

  • The objective of this report is to set out a district typology according to land cover structure, and this will be achieved through the use of statistical methodologies. An intermediate objective is to establish land cover change trends

  • Cover crops are a very effective erosion control and environmental conservation technique. When cover crops freeze at the beginning of the winter period, the above-ground biomass becomes less effective in protecting the soil from water erosion
  • , but roots can still play an important role in improving soil strength. Therefore, root density distribution with soil depth and the erosion-reducing effect of these cover crops during concentrated flow erosion were assessed by conducting root auger
  • . Fine-branched root systems (such as ryegrass and rye) are less vulnerable to frost. Ryegrass, rye, oats and white mustard are suitable cover crops to prevent concentrated flow erosion.

  • Polar desert vegetation and plant recruitment in Murdchisonfjord, Nordaustlandet, Svalbard
  • A vegetation survey in the vicinity of Kinnvika in Murchisonfjord, Nordaustlandet, was carried out at 23 sites ranging from sparsely vegetated to almost complete cover on the slopes under a birdcliff. In total, 36 vascular plant species were
  • recorded in the area, 28 species under a birdcliff and 21 species at the other sites. At moisture limited sites, recruiting plant density significantly correlated to cyanobacterial crust cover. This crust ameliorates the substrate surface providing moisture
  • , warmth, nutrients and a more stable environment for establishing plants, and is thus of major importance for plant community development in High Arctic polar deserts.

  • Integrating geographical data and phenological characteristics derived from MODIS data for improving land cover mapping
  • China ; Comparative study ; LANDSAT ; Land use ; North-Eastern China ; Phenology ; Plant cover ; Satellite imagery ; Soil properties ; Thematic mapping
  • The study developed a feasible method for large-area land cover mapping with combination of geographical data and phenological characteristics, taking Northeast China (NEC) as the study area. First, with the monthly average of precipitation
  • with phenological variables derived from the moderate resolution imaging spectroradiometer (MODIS) data (enhanced vegetation index (EVI) and land surface water index (LSWI)), which were taken as input variables of land cover classification. Decision Tree (DT
  • ) classifiers were then performed to produce land cover maps for each region. The results highlight that this land cover map produced (NEC_MODIS) has a good performance.

  • Effect of ground cover on splash and sheetwash erosion over a steep forested hillslope : a plot-scale study
  • Experiment plot ; Forest ; Honshu ; Japan ; Plant canopy ; Rill wash ; Sediment transport ; Slope ; Soil erosion ; Splash ; Water erosion
  • The contributions and relationships of erosion by splash and overland flow over a steep slope in a Japanese beech forest in plots with different percentages of ground cover were examined. Three erosion plots with average understory coverage of 1
  • %, 45%, and 94% were installed. Sediment transported by rain splash and by overland flow was sampled separately. The sparse ground cover showed the largest variation of splash and sheetwash contribution in soil erosion. This variability was due
  • to variation in ground cover and soil surface wetness condition which led to a variation of detachment and non-linear relationship of sheetwash splash.

  • The AA. analyze variation in soil moisture, water availability for plants, and drying processes on the hillslopes, and relationships between these factors and the annual variability of vegetation cover. The results show that clay content is a key
  • factor defining the limit of water availability in the soil (the wilting point). Significant differences between soil moisture/available water and vegetation cover were observed, defining a positive feedback process that varied in nature along
