“…In these areas, seasonal grass covering steep (25-40°) hillslopes is frequently removed by soil slips during heavy rainfall. These steep slopes, however, become stable if they are colonised by shrubs whose roots anchor deeper into the thin soil mantle (Ferrari, 1971;Ferrari and Speranza, 1975;Ferrari and Gerdol, 1987).…”

“…Ferrari (1971) subdivided the Table 4 Measured root TS for shrubs (this study) and TS for trees (Greenway, 1987) Species badland-like environment into three main geomorphic units with different gradients and different grass and shrub associations: 1) low gradient (b 15°) convex ridges between steep gully walls; 2) steep (N 40°) facets extending along gullies; and 3) fan/cone/talus surfaces (slope 10°-35°). Relationships between the presence of I. viscosa (L.) or S. junceum (L.) and the three geomorphic units were evaluated using the phytosociological data obtained by Ferrari (1971), Ferrari and Speranza (1975) and Ferrari and Gerdol (1987). I. viscosa (L.) (subass.…”

“…Sin embargo, algunos fitosociólogos italianos han constatado la existencia de una serie de asociaciones vegetales que caracterizan la vegetación de algunas zonas de Italia, que incluyen desde áreas débilmente acarcavadas (localmente biancane) hasta las que lo están más intensamente (calanchi) (ALLEGREZZA et al, 1993;BIONDI et al, 1988;BIONDI et al, 1990;BIONDI et al, 1992;FERRARI and GERDOL, 1987). Fuera de Italia y también desde un punto de vista fitosociológico, se han estudiado algunas comunidades vegetales propias de los "badlans".…”

“…En ocasiones, las tipologías de plantas utilizadas han sido las estrategias anuales vs. perennes o las formas vitales de Raunkiaer (FERRARI and GERDOL, 1987;JIMÉNEZ-MARTÍNEZ et al, 1992;LÁZARO SUAU, 1995). En otros casos, se ha investigado la respuesta de diversos tipos y atributos vegetales a la pérdida de suelo (DANIN, 1996;GUARDIA, 1995;GUERRERO-CAMPO, 1998) e, incluso, se ha intentado analizar la variación de estrategias funcionales de las plantas al aumento de la erosión (HODGSON et al, 1994).…”
