  • Vegetation succession and soil cover transformation after extreme flood : a case study from the Sázava River floodplain
  • Czech Republic ; Flood ; Floodplain ; Plant cover ; Plant succession
  • The goal of this study was to assess impact of flood on soil and vegetation cover in the Sázava river floodplain after an extreme spring flood in 2006.There was a significant difference in species' composition between eroded sites and sites on thick

  • Based on journal publications and a meta-analysis approach, this paper investigates the effects, and their spatiotemporal variations, of different land covers on red soil rehabilitation in China. Results indicate that all the land covers used in red
  • soil rehabilitation had been effective in improving degraded red soils but the degrees of effectiveness varied. Soil organic carbon was the most sensitive of the 3 major soil nutrients considered with regard to land-cover change during ecological
  • rehabilitation. Coniferous and broadleaf mixed forest was detected as the most effective land cover in red soil rehabilitation. Some spatiotemporal trends of land-cover effectiveness on red soil rehabilitation exist in a statistically significant sense

  • is related to extrinsic habitat conditions (planting site, ground cover, land cover, and district) and intrinsic tree traits (species provenance, seasonality, tree dimensions). A total of 6,351 trees were evaluated. District differentiation in tree
  • This paper focuses on the urban biogeographical study of tree quality with regard to habitat conditions that vary mainly by land cover. Statistical analysis, including logistic regression, was used to test the hypothesis that tree performance
  • performance was related to land cover. Exotic and evergreen species grew better than indigenous and deciduous, offering hints on species-habitat matching. Detailed field and statistical analyses could yield tree-environment information to enhance urban

  • Modified MMF (Morgan-Morgan-Finney) model for evaluating effects of crops and vegetation cover on soil erosion
  • This paper describes modifications made to the MMF model to allow the effects of vegetation and crop cover on erosion to be expressed through measurable properties of plant architecture instead of empirically derived coefficients. Tests
  • with this modified model using field measurements under a range of slope, soil and crop covers from Bedfordshire and Cambridgeshire, UK, give good predictions of mean annual soil loss.

  • Runoff and sediment lost due to water erosion were recorded for 36 plots with varying types of vegetative cover located on sloping gypsiferous fields in the South of Madrid. Vegetative cover above 40% is capable of dissipating the relationship
  • between runoff and sediment loss, especially when the vegetative cover is greater than 60%. The soil here experiences a chronic loss of 0.02 mm annually as a consequence of frequent, moderate events, in addition to any loss produced by extraordinary events

  • Impact of plot length on the effectiveness of different soil-surface covers in reducing runoff and soil loss by water
  • Erosion rate ; Experiment plot ; Plant canopy ; Runoff ; Slope gradient ; Soil erosion ; Water erosion
  • The main aim of this review is to explore to what extent the impact of plot length on the effectiveness of different surface covers (rock fragments, organic mulch and vegetation) in reducing runoff and soil loss by water erosion emerges from
