Conserving biodiversity in the context of global change is a challenge for the sustainability of life as we know it. Scientific protection work, particularly for flora, often lacks interdisciplinary approaches that consider human dynamics. The main objective is to evaluate the level of commitment of Spanish society toward the conservation of biodiversity in general and vascular flora in particular. As a secondary objective, it aims to contribute to the transfer between management and the general population. Methodologically, the survey has been used to estimate the willingness to protect threatened flora. The surveyed population is structured on the basis of its commitment to biodiversity conservation into: pro-conservation or pro-utilitarian group. The results are conclusive and indicate a high commitment of the Spanish society to conservation in aspects such as fees or legislative limitations on owners. It also reveals a deficiency in the transfer of the efforts made, from management, to society. It can be concluded that the survey, as a tool, allows us to know the starting social reality, detect weaknesses and deficiencies that allow management to be adapted to that reality, replicate work longitudinally to know the evolution of the measures and, indirectly, bring reality closer, of conservation to the people surveyed (science transfer).
