The colour spectacular trees treat us to each autumn before their leaves fall could be at risk from climate change, says the National Trust.
Over the next few weeks we will see just how much the summer heatwave and droughts have impacted trees.
While some have shown signs of autumn early, overnight temperatures must drop before the leaves really start to turn. But the Trust says signs of stressed and struggling trees have been seen across Northern Ireland, with many thinking autumn arrived early carpeting the ground below them in August.
