The primitive physiognomy of the middle section of the Ebro Valley consisted of an extensive riverbank forest with numerous enclaves flooded almost permanently. Witnesses of this landscape, today still survive some old meanders abandoned by the river after heavy floods and that in Aragon are known by the name of galachos. At present, those of LA ALFRACA DE PASTRIZ, LA CARTUJA and EL BURGO DE EBRO are protected, constituting one of the best conserved riparian ecosystems of our Autonomous Community.

Galachos of the Ebro.

Since ancient times, these fertile lands have been the place chosen to locate important human settlements attracted by assured irrigation and good communications.
Progressively, the crops were stealing land from the riverbanks, but until the nineteenth century they still kept certain distances from the river bed. It is during this century that the successive clearings, fellings and extractions of aggregates, added to the channeling of several sections of the river, have destroyed a large part of the Ebro groves.

As of 1965, the protection of the Galacho de La Alfranca is claimed by numerous naturalists. In 1973 it was drafted by ICONA, the body responsible then for the conservation of nature, a protection project that would never see the light and in 1976, under the Law of Hunting, the total closure is achieved in this enclave. In 1982 the systematic campaigns began to ask for the protection of the galachos, obtaining the paralyzation of some burns in La Alfranca. After a great fire in 1986, a commission formed by technicians of the Diputación General de Aragón and representatives of the Ecological Coordinator of Aragón was formed, with the purpose of preparing a draft of a protection project that culminated in 1991 with the declaration of the NATURAL RESERVE OF THE GALACHOS OF LA ALFRANCA DE PASTRIZ, LA CARTUJA AND THE BURGO DE EBRO.

This area has become a place of recreation for the people of Zaragoza, being very frequented by hikers. As a result, new problems such as the increase of garbage have appeared in this Natural Space. However, the Reserve has also become a magnificent outdoor classroom, in which to carry out Environmental Education Programs. From the Interpretation Center of La Alfranca, various activities with schoolchildren and the population in general take place throughout the year.

These three galachos constitute the only riparian ecosystem in Aragón protected under one of the figures of Law 4/89. Guarantee the survival of these scarce natural spaces, avoiding any action that involves its deterioration is the main objective of its protection.
