The planned actions are part of the irrigable area of Lobón, specifically in the following rivers: Guadajira River (19.05 km), Arroyo del Entrín Verde (7.6 km), Arroyo del Golfín (4.9 km) and Arroyo Valdehombres Colorado (2.1 km). The Montijo Irrigation Area is located northwest of the province of Badajoz, on the right bank of the Guadiana River, between Merida and Badajoz, with an area of 14.99 ha. The channels included in the project are located in the municipalities of Badajoz, Merida, Talavera la Real and Lobón. The main actions are: Silvicultural treatment on existing vegetation and trees progressive elimination of foreign species; Plantations with native species for restoration of vegetation cover; Cleaning of sludge and invasive vegetation in rivers; Performances of landscaping: removal of debris, waste, rubbish, demolition of concrete, etc.; Protection and promotion of wildlife: placing artificial nests, artificial shelters, etc.; Reorganization of the social use: install interpretive and informative signage and marking of pedestrian paths using the existing paths; and Control and monitoring environmental, legal advice.
