摘要: Following the Water Framework Directive guidelines, several ecological indicators were examined in rivers Jiloca and Pancrudo, such as fish, benthic macro-invertebrate riparian communities, habitat elements hydrogeomorphic attributes of fluvial system. For evaluation indices calculated: IBMWP IASPT using macro-invertebrates; QBR, or Riparian Vegetation Quality Index, IHM, parameters index. The results show that River has a poor quality Pancrudo moderate one. main factors associated with degraded condition are surface perforations flow detractions, untreated sewage effluents, channel dredging straightening, zone alteration. In spite condition, have valuable assets to preserve, an autochthonous common trout (Salmo trutta) population, isolated old-growth black poplars zone, sections relatively unaltered morphology, rare wetlands, preservation which must be priority, previous rehabilitation plan developed meet requirements Directive.
