Phénoclim is a scientific and educational programme that invites the public to contribute to the assessment of the impact of climate change on mountain fauna and flora. Launched in 2014 in the Alps at the initiative of CREA Mont-Blanc (Centre de Recherches sur les Écosystèmes d'Altitude), this programme is based on two scientific disciplines: FENOlogy and CLIMAtology to highlight the rhythms of nature.  The data collected in the different mountain ranges allows researchers to understand better the functioning of ecosystems for each season of the year, in order to be able to study the effects of climate variations on the environment.

In the Pyrenees, Phénolcim is run jointly by CREA Mont-Blanc and the Réseau Education Pyrénées Vivantes (Living Pyrenees Education Network), coordinated by the LPO (League for the Protection of Birds), within the framework of the FLORAPYR project led by the Conservatoire botanique national des Pyrénées et de Midi-Pyrénées (National Botanical Conservatory of the Pyrenees and Midi-Pyrénées) and by the OPCC2 project led by the Working Community of the Pyrenees.


Phenological studies consist of the evaluation of seasonal events taking place in living beings. Within the framework of the Phénoclim programme, observers closely monitor the phenological evolution of various plant species (bud opening dates, flowering and leaf colour changes) throughout the seasons.

The 13 species of trees and plants typical of the Pyrenean range, proposed for monitoring are:

How to participate in Phénoclim in the Pyrenees?

Present around us, the trees and other plants selected for the monitoring program are easy to observe as long as you pay attention to the details that differentiate the different important phenological stages.

To participate in the observation ofthe flora, it is necessary to follow some steps:

Firstly, you will have to select and describe very accurately a chosen observation area (your garden, a forest in the vicinity of your home...) where there are at least three of the plants or trees of three different species from among the 13 plant species studied in the context of this initiative.  After marking the chosen specimens to be sure that you will be able to recognize them throughout the different seasons, all you have to do is to complete the information fields on the Phénoclim website relating to the observation area (such as altitude, exposure, etc.) and the chosen species.

In spring and autumn, you will have to visit once a week the chosen site to monitor the evolution and note the dates on which you have observed the stages of phenological evolution described in the protocol (budding, flowering, leaf development). The various photos and additional information contained in the monitoring protocol will help you in carrying out the monitoring correctly.

In order to facilitate the transmission of observation data, we invite you to download the Phénoclim app that will allow you to send the data in real time to the programme technicians for validation and subsequent insertion into the visualization tool.
