RitmeNatura was born in 2018 as an evolution of the citizen observatory FenoDato , based on phenological observations made by citizens through Twitter . The Fenodato project was financed in 2015 by the Spanish Foundation for Science and Technology (FECYT) and developed a community of phenological observers throughout Spain who contributed their data through #FenoTweets .

In 2016, FenoDato became a case study of the European project Ground Truth 2.0 , funded by the European Commission within the Horizon 2020 program. The objective of Ground Truth 2.0 was to offer the demonstration and validation of six citizen observatories in real operational conditions in the Netherlands, Sweden, Kenya, Zambia, Belgium and Spain to demonstrate the technological feasibility, sustained use and social and economic benefits of those citizen observatories.

Within Ground Truth 2.0, the observatory went through a process of reconsideration and co-design common to the six case studies that led FenoDato to be reborn and become what it is today, RitmeNatura, a citizen science observatory thought, designed and supported by citizens, scientists and managers with a common goal: to contribute to the study of phenology in order to have robust, valid and conclusive data on the effects of climate change on living beings.
