Heat Resistance of Trees
May 12, 202500:15:51Tap to summarizeIn this Monday episode of Talking Trees, we explore how urban trees respond to rising temperatures and what determines their heat resistance in the face of climate change and the urban heat island effect.We discuss:The physiological and biochemical effects of heat on trees, including impacts on photosynthesis, respiration, and water regulationMethods to assess heat tolerance, from leaf-level tests to remote sensing technologiesWhy urban trees are particularly vulnerable due to limited rooting space, reflective surfaces, and compacted soilsStrategies to enhance heat resilience: species selection based on provenance, breeding programs, and targeted fertilisationThe critical gap in research focusing specifically on urban tree species, and the need to prioritise this area for sustainable city planningSelecting and managing trees for heat resilience is key to maintaining urban canopy cover and the essential ecosystem services it provides.Background information:Percival. 2023.
