The main objective of PEP725 is to promote and facilitate phenological research by delivering a pan European phenological database with an open, unrestricted data access for science, research and education.
PEP725 is a Module of the EUMETNET Climate Programme. PEP725 was made possible by the continued support of EUMETNET and GeoSphere Austria.
Plant phenology is the study of the timing of natural plant processes, such as leaf sprouting, flowering and leaf shedding in autumn. These seasonal changes are influenced by environmental conditions, particularly temperature and daylight hours.
In the context of climate change, plant phenology is particularly significant because these events are changing. For instance, many plants are flowering earlier in spring due to rising temperatures; some extend their lifespan into autumn. Tracking these changes helps scientists to understand how ecosystems are responding to climate change. This can affect agriculture, biodiversity and the timing of food availability for animals and humans.
Many European countries have observation networks that monitor developments in plant life. Our project aims to collect national data from these networks and make it available to all interested parties in a standardised format — particularly the scientific community, but also anyone interested in how nature responds across Europe.
We warmly congratulate the Swiss Phenology Observation Network on reaching 75 years of continuous, invaluable work! Since its founding in 1951 by Bernard Primault of MeteoSwiss, the network has depended on the steadfast commitment of over 700 volunteer observers spread across 160 sites, tracking the seasonal rhythms of 26 native…
