With the Pronouncement of the Sierra de Guadarrama National Park, the Spanish Parliament recognized, that the natural space that integrates it, has an ecological and cultural wealth so outstanding, that they advise its preservation has to be declared of General Interest, and to elevate its protection regime at the highest level allowed by our legal system.
This recognition was promoted from the Communities of Madrid and Castilla y León, by means of signing, on March 25, 2002, a Collaboration Protocol for the definition of a Natural Resources Management Plan, within the framework of which would be analyzed the possibility of declaring a National Park. Further to the previous planning, with the approval of the Natural Resources Management Plan, by Decree 96/2009 of the Community of Madrid and Decree 4/2010 of the Community of Castilla y León, the process culminated in a proposal for a declaration of National Park which was approved by both Communities Legislative Assemblies. The Ministry of Agriculture, Food and Environment considered the proposal was appropriated, and that it complied with the requirements provided in Law 5/2007, of April 3, of the National Parks Network (currently replaced by Law 30/2014 of National Parks). In the same vein, the Council of the National Parks Network was pronounced.
The Central Government produced an Act Proposal which, after being reviewed in both chambers, was approved on June 25, 2013. The law includes 15 articles in which the objectives are defined, as well as the different territorial areas (National Park, Peripheral Protection Zone and Socioeconomic Influence Area), the protection regime of these areas, organization of management and coordination, economic regime, planning instruments, citizen participation modalities, and sanctioning regime.
