This dataset compiles a catalogue of forest restoration and adaptation projects and activities in Spain. The compilation was mainly carried out through a systematic search of European funding programme databases (such as LIFE, INTERREG, or SUDOE) and national sources (such as Fundación Biodiversidad). Additionally, initiatives not recorded in databases were identified through expert networks and partner organisations. The database includes over 350 projects and provides detailed information on various aspects such as title, acronym, geographical scope, start and end dates, summary, degradation causes, restoration objectives, main outcomes, budget, funding source, coordinating entity, among others. To complement the collected information and facilitate analysis, all projects have been categorised according to their objectives, degradation causes, and type of restoration undertaken, using predefined sets of categories. This dataset was developed within the framework of the REFORADAPT project, with the support of Fundación Biodiversidad from the Spanish Ministry for the Ecological Transition and the Demographic Challenge, through its grant call for projects contributing to the implementation of the National Climate Change Adaptation Plan 2021–2030. The dataset is provided as a CSV file, where each row represents a project and each column corresponds to an associated variable. A README file with the corresponding metadata is also included, available in both English (README_en.txt) and Spanish (README_es.txt) versions.
