Spring

With spring almost upon us, CREAF’s experts are reporting that this year could be a chance for Catalonia’s forests to recover from accumulated past droughts and the devastating effects of the pine processionary. There will be no let-up for the territory’s undergrowth, however, with the box tree moth’s continuing expansion leaving just 20% of box plants with new growth.

At this time of year, deciduous trees across Europe are losing the last of their leaves. When will they come into leaf again? A study just published in Nature Communications has shown that while year-to-year leafing date variations can be explained by heat accumulation, local climate is a key factor in geographical variations.
