“…However, the significant effect of the basal area as a gully erosion controller can be associated to the role of the tree roots, especially from mature forests, as soil stabilizers (Gyssels et al, ). Whereas the dominance of young forest from reforestation plans, together with accompanying soil preparation works, can actually increase the sedimentation rates of gully erosion, which can be higher than in undisturbed shrubland in semiarid areas according to Williams et al (). Additionally, land use changes from 1987 to 2005 showed increase in agricultural, bare areas and urban land uses in gullied drainage areas.…”

“…Forest information used for land degradation processes is usually defined by variables such as canopy cover, often feed into already predefined empirical models such as RUSLE (Zhou et al, ; Mohammad & Adam, ; Jamshidi et al, ) or expert models (Lavado Contador et al, ) used for estimating the vulnerability of sites. There are also few studies using empirical data for evaluating the impact of forest related variables on sediment losses, most of them focusing on the impact of specific events, such as logging operations (Williams et al, ; Hartanto et al, ; Slesak et al, ) or recreational activities (Selkimäki & Mola‐Yudego, ), and seldom on the impact of more general features such as forest structure and species composition (Selkimäki et al, ). Regarding gully erosion, it is recognized that forest has an impact on preventing or stabilizing gully erosion (Dotterweich et al, ; Rey, ).…”

Gully erosion is an important land degradation process affecting soils around the world. This paper studies gully erosion in forest lands, analysing related local and environmental factors influencing its occurrence in Catalonia (north-east Spain). The data on gully erosion are based on observations from the Third Spanish National Forest Inventory, and include 157 plots with gully erosion and 9932 non-eroded plots for reference. The variables studied as potentially related to gully erosion occurrence included characteristics of the forest plots and variables describing drainage areas, such as land use configuration and edaphic and geological characteristics. For evaluating these factors affecting on gully erosion occurrence, a binary logistic model with stepwise selection of variables was used. The final model explained 30·4% of the variance. According to the results, the probability of gully erosion occurrence was increased with larger drainage area, steeper slope, presence of fine textured soils, increased urban land use and presence of unpaved roads. On the other hand, the dominance of forest and the presence of paved roads on the drainage area diminished gully erosion probability. The presented model can be used for mapping the areas with higher gully erosion risk, in an effort to direct land use planning and management in order to mitigate soil losses.

“…Studies regarding relationships between erosion and natural vegetation in Spain, have been carried out since the 1980s (Morgan et al, 1990;Quine et al, 1994;Williams et al, 1995;Cerdá, 2001). The major role played by shrubs in the erosion control in Spain has been deal with works from Francis and Thornes (1990); Andreu et al (1994); Andreu et al (1995);and Ruecker et al (1999).…”

Reducing water erosion in a gypsic soil by combined use of organic amendment and shrub revegetation

et al. 2005

Degraded gypsic soils in the centre of Spain can be rehabilitated with organic amendment and shrub revegetation. Erosion has been measured on plots of 2 Â 0Á5 m 2 under simulated rainfall of 70 mm h À1 and a kinetic energy of 18 J mm À1 m À2 . Samples of water runoff and sediments were studied in the summer of the years 2002 and 2003. The presence of shrub Atriplex halimus (Chenonodiaceae) significantly reduces runoff from 16Á9 to 6Á7 ml m À2 min À1 and sediments from 0Á16 to 0Á02 g m À2 min À1 . When sewage sludge is applied the differences among plots with and without bushes disappear. Although both treatments independently applied are efficient as erosion control measures, the combined use of revegetation and organic amendment allows a reduced dose of sewage sludge with the same effect on erosion. A low dose of sludge is desirable in view of the accumulation of toxic chemicals.

“…The construction and maintenance of ski runs on steep slopes requires erosion control measures to prevent soil loss. Although physical erosion control features, like berms, are often constructed, the re-establishment of vegetative groundcover is critical in reducing runoff and soil loss as it binds soils and increases infiltration rates (Andreu et al 1995, Williams et al 1995, Oliver and Larson 1990, Marks and Bormann 1972. Natural re-establishment of indigenous vegetation in disturbed areas may take years (Curtin 1995, Dyrness 1973, dictating the need for artificial seeding to re-establish vegetative groundcover quickly.…”

The cover of native and non-native introduced plants was compared between seeded (reclaimed) ski runs and adjacent or nearby unseeded (control) areas at a managed ski area in northern Arizona to determine the potential effects of revegetation efforts on plant species composition of the area. Although vegetative cover was similar, plant species richness was significantly lower on reclaimed ski runs compared with control areas. At 3 of 4 sites, the number of plant species was more than 2-fold greater in control areas, although species richness was similar between control and reclaimed areas at 1 site. The proportion of native species was more than 3-fold greater in control areas compared with reclaimed ski runs. The proportion of non-native species was more than 5-fold greater on reclaimed ski runs than in control areas. Although sites differed substantially in time since seeding, no evidence was found at 3 of the 4 sites for either an invasion of non-native species into the native plant community, or significant re-establishment of native species in reclaimed areas. Relatively high biomass of native species on a reclaimed ski run at 1 site appeared to be tied to a low level of initial disturbance and favorable conditions for growth. Results suggested that minimizing initial soil disturbance, retaining topsoil, and maintaining islands or patches of natural vegetation within cleared areas promoted the re-establishment of native species on ski runs.
