Spring of 2013 was the coldest since 1987 and the spring of 2011 was the warmest of the 20th and 21st centuries. These exceptional years directly influence the phenology of animals and plants. As a result, all spring stages for the flora studied were very late in 2013, whereas conversely, 2011 was very early for all species.

Interannual climate variability needs to be based on the series of data covering a long enough period in order to detect a trend.

How do species adapt each season to climate variations?

Despite being in existence for 10 years, the Phenoclim programme has not been around long enough to allow it to detect strong trends in the influence of climate change on the gap in the phenological stages. It is over the very long term that scientific studies must be recorded in order to fulfil their objective: to understand the impact of the temperature increase on ecosystems.
