  • Photographs of the vegetated North and East Forelands of Anak Krakatau, which emerged from the sea in 1930 and was totally devastated by volcanic activity in 1952/53, provide some evidence of rate of change of plant cover from grassland to woodland

  • Trampling damage to vegetation and soil cover within the Burren National Park, Mullach Mor, Co. Clare
  • Biogenic action;Biogenic process ; Biogeography ; Degradation ; Environment ; Fauna ; Ireland ; National park ; Plant canopy ; Soil erosion ; Vegetation
  • Between 1986 and 1992, surveillance of three selected paths revealed a pattern of increasing damage to vegetation and soil cover. An attempt was made to quantify the extent of trampling damage, and to examine possible causes of observed spatial

  • Natural vegetation of coal waste areas is sparse and patchy with low plant cover. More than 50 native plants species frequently occur there; they are better suited to recolonizing such sites than are exotic plants. - (DWG)

  • Cattle began to affect the Paramo de Piedras Blancas in the nineteenth century. Browsing the leaves of one rosette species, « Coespeletia timotensis », has severely affected almost half the plant cover in places.―(DWG)

  • Land cover forms in Slovakia identified by application of colour infrared space photographs at the scale 1:500 000
  • The land cover patterns identified in 22 categories from an environmental point of view document the present landscape structure as a reflection of natural, social, economic and political conditions of the Slovak territory. - (MS)

  • Climatic change, snow-cover and avalanches
  • Firstly snow as material and the climatic role of a snow-cover are described. Secondly, past changes of the Alpine snow-cover (quantity and quality), key variables and recent trends are enumerated. Finally, past fluctuations of avalanche activity

  • Runoff and sediment yield from topsoils with different porosity as affected by rock fragment cover and position
  • This paper analyses the relations between cover and position of rock fragments in topsoils on the one hand and interrill runoff and sediment yield on the other for two topsoils with different types of structure : i.e. a soil with essentially
