Background information and definitions
Cities generate large amounts of heat, and as a result are often warmer than surrounding areas of natural habitat, a phenomenon known as the ‘urban heat island effect’ (Kleerekoper et al. 2012). For species which are otherwise able to survive in cities, higher temperatures may cause problems for survival and reproduction. Planting trees within cities provides shade, and actively cools the environment by increasing evapotranspiration (Kleerekoper et al. 2012). This may provide benefits for temperature-sensitive butterflies and moths, but could be detrimental if the trees replace other important habitats.
