During periods of extreme heat, trees can become more susceptible to falling, a phenomenon that environmental experts are warning the public about. The intense temperatures associated with heatwaves can significantly stress trees, compromising their structural integrity.
While the exact mechanisms can vary, the combination of high temperatures and lack of moisture, a common feature of heatwaves, can lead to a weakening of the tree's root system and overall structure. This weakening makes them more prone to toppling, especially when subjected to additional pressures such as wind or simply their own weight.
Experts advise caution, particularly recommending that individuals avoid seeking shelter under trees during heatwave conditions. The risk is not limited to the most severe heat events, as prolonged periods of high temperatures, even if not record-breaking, can contribute to the gradual weakening of trees over time.
