Scientific projects can greatly benefit from the participation of non-professionals in identifying environmental changes at a variety of spatial and temporal scales. In 2010, we launched a long-term project in Northeast Spain (MONITO) that has recruited more than 200 volunteers and rangers. Participants monitor regional-species distribution and local-population abundance for a wide variety of plant species: threatened, rare, and indicators of climatic change or habitats of interest. At the local abundance level (the novel Adopt-a-plant program), they carry out annual censuses of population abundance for 10years at least, to eventually estimate standard trends and future vulnerability. In order to show the functional structure of the network and facilitate implementation elsewhere, we evaluate the key aspects of MONITO, which currently involves 183 single-species or multi-species monitoring sites. We use the participant database, an anonymous survey, and the analyses of time invested in fieldwork training, participant turnover, and scientific assessment of monitoring quality. No significant differences were found between volunteers and rangers regarding time invested per monitoring site, quality of data collected, or primary motivation (participating in a real scientific experience). Volunteers fit better the local abundance level and reach higher satisfaction and learning. Rangers contribute more to the distribution level and present a higher turnover throughout the monitoring period. MONITO represents a successful way of tracking real biodiversity changes and connecting scientific research to public outreach. Mentoring is a key element of this project, together with a socially integrative (participants with and without experience) and methodologically complementary approach.
