Project summary

Edit project overview to modify the project summary.

The River Chícamo is located within the SCI of the Chícamo River (SCI ES6200028), hosting 8 habitats of community interest. The Chícamo River rises near Macisvenda, a small village belonging to the Abanilla municipal district, one of the most arid places in Murcian Region, which gives this scenery a special peculiarity. It is a permanent flow river with related temporary watercourses and wetlands. You can find different community plants such as Nerium oleander (Rosebay), Tamarix boveana and Tamarix canariensis ; also, some endemic plants as Sideritis leucantha and Thymus moroderi. In terms of fauna, the Spanish toothcarp ( Aphanius iberus ) stands out, as the only presence of this species in continental courses in Murcian Region, included in Annex II of Directive 92/43/CEE, together with the invertebrate Coenagrion mercuriale (Southern Damselfly); Himantopus himantopus ( Black-winged Stilt) , included in Annex I of Directive 79/409/CEE is also present. The Chícamo River source is a natural river with shorter than 3.5 km , 1.5 m of average width and no more than 75 cm of average depth. The whole project comprises actions in different places of Murcia: Ajauque's wetland and “Rambla Salada”, Marchamalo” saltflats, "Rasall" saltflats and the River Chícamo. The actions at the River Chicamo and Marchamalo saltflats were aimed to increase the physical habitat availability, the Rambla Salada´s complex rehabilitation was destined to create a centre for re-establish and semi-captivity control of a “Chícamo” River stock population, and the restoration of the “Rasall” saltworks aimed to re-establish a Spanish toothcarp population that belongs to the genetic stock who lives in “Marchamalo” saltflats. The measures on the River Chícamo were: creation of a water intake through the rehabilitation of an old channel; construction of two bridges and restoration at these places in order to increase the aquatic habitat; creation of new pools to increase habitat quality; control of invasive species Gambusia holbrooki and Procambarus clarkii and monitoring and evaluation of abundance and structure of Spanish toothcarp´s population and invasive species populations.
