| Abstract |
The “ramblas” (dry watercourses) are one of the most characteristics
geomorphological elements in the south-eastern part of the Iberian
peninsula, where they play an important role as vector of rapid
evacuation of water after torrential precipitations. However, the fact
that they no have permanent water have been a determining factor at time
to carry out actions of recovery, being most of them in a high degree of
disturbance. In this work is presented a model of recovery of the
traditional appearance of a south-eastern rambla, with particular
emphasis in the typical vegetation of the zona and its value as element
of landscape. The area of study has been the urban strech of the rambla
of Chirivel, that runs in paralell to the locality of same name in the
province of Almeria. To know the current environmental state of the
rambla, the description of the different plant communities present have
been done, as well as the data regarding the degree of coverage,
conectivity and land-use. The tipology of the rambla has been defined in
base to a series of parameters and the main impacts detected on it, both
natural and of anthropogenic origin, have been listed. The results show
that the anthropogenic activities are those generating the highest
number of impacts, being remarkable the traffic of vehicles, the
abandonment of agricultural land and inappropiate activities of
reforestation. The proposal here presented promotes a recovery at
different levels: botanical, using the autochthonous species of the area;
environmental, to minimize the existing impacts; ecological, maintaining
its functionality of vector of transport of water, and landscaping, to
return to the rambla all its value as characteristic element of arid
zones. |
