Scientists say signs of spring are appearing earlier in woodlands because of temperature rises in past decades.
They predict that climate change will alter the order in which different trees start to grow leaves, with long-term implications for the survival of some woodland plants.
A 200-year-old record from a Norfolk estate shows warmer springs are causing most woodland plants to leaf earlier.
But warmer autumns are having the opposite effect on some species.
It is shifting the timing of when different trees grow leaves and flowers, according to biologists at the University of Edinburgh.
