The Turó de Montcada is within the Natura 2000 Network, what does this imply?

The objective of the Natura 2000 Network is to maintain habitats and species of community interest in a favourable conservation status. This implies that there are a series of restrictions and limitations.
The inclusion of a territory in the Natura 2000 Network entails the duty, on the part of the owners, to comply with the obligations arising from the respective Community Directives. For their part, the Public Administrations must ensure and guarantee their compliance.

This is also included in article 45 of Law 42/2007 on Natural Heritage and Biodiversity, only allowing the carrying out of projects or actions in these spaces if they are fully justified and following a fairly strict procedure.
In general, some activities, such as forestry, hunting, recreational and sports uses, are very restricted.

In 1992, the European Union approved Directive 92/43/EEC of 21 May on the conservation of natural habitats and of wild fauna and flora, better known as the Habitats Directive. As a precedent, Directive 79/409/EEC of 2 April 1979 on the conservation of wild birds (collected by the Habitats Directive), known as the Birds Directive, had been approved thirteen years earlier. These two regulations, which were subsequently transposed into Spanish legislation, are the legal framework for the creation of the Natura 2000 Network.

The overall objective of the Habitats Directive is “to contribute to ensuring biodiversity through the conservation of natural habitats and of wild fauna and flora in the European territory of the Member States”. Therefore, the Directive aims to conserve biodiversity while protecting habitats and species. The main instrument to achieve this objective, although not the only one, is the Natura 2000 Network, a coherent European system of protected areas that should integrate representative samples of natural habitats of Community interest, on the one hand, and of the habitats of species of Community interest, on the other. The concept of Community interest depends on whether it is applied to a habitat or a species, but broadly speaking it means that both are threatened with extinction, have a reduced distribution area or require special attention due to their uniqueness.

The Natura 2000 Network is made up of two types of sites: Special Areas of Conservation (SACs) and Special Protection Areas for Birds (SPAs). SACs are designated by the Member States in accordance with the Habitats Directive. Prior to this designation, however, it is necessary for the European Commission (EC), in agreement with the member states, to classify the proposed sites as sites of community importance (SCI).
