Modelo para determinar áreas susceptibles a la expansión del retamo espinoso (ulex europaeus l.) mediante el uso de herramientas espaciales en la localidad de Santa fé, Bogotá D.C.

Abstract

The oriental hills of the city of Bogotá D.C. in their origins they presented environmental conditions different from the current ones. These were characterized by rocky landscapes with low soil density and therefore little vegetation, in the 50s it was tried to change the landscape of the eastern hills introducing exotic species in order to give greater density to these areas of the city and generate an environment of landscape more favorable for the hills. In this incorporation of species, exotic varieties such as eucalyptus and pine began to create another kind of vegetation cover in the soils of the eastern hills. As these coverages were increasing, the development of the city was also given, in this period of time, water sources became vital for the supply of the communities, based on this, it is understood that the bodies of water may be susceptible to illegal seizures, which is why in the decade of the 50s, administrative decisions were taken to protect or close fences with live fences with water bodies with the exotic species called thorny reed (Ulex europaeus L.). which, as the name implies, generates an impenetrable barrier given its harsh-sharp condition. The thorny reed (Ulex europaeus L), is characterized by vertiginous growth considering that its reproductive mechanisms are highly accelerated in addition to being pyrrhite, that is, it is prone or has affinity with generating forest fires1, which has represented environmental risks high levels involving harmful ecosystems and strategic water sources of the eastern hills of the city of Bogotá. The study will focus on the third location of Santa Fé, a territory with a rural area that occupies 82% of its jurisdiction, its paths Monserrate, Guadalupe, El Verjón Bajo and Alto have entered into environmental and social conflict due to the expansion of the thorny reed (Ulex europaeus L.), it requires a correct and effective attention to address this problem. This is how Geographic Information Systems (GIS) can be a fundamental tool in the identification, modeling and evaluation for decision making and / or planning for the subsequent eradication of the exotic space that is damaging the Eastern hills of the city ​​of Bogota.
