What Will Urban Heat Islands Do on Wildlife and Biodiversity? | CBCGDF Climate Change Working Group

Urban heat islands, areas in cities that experience higher temperatures than their rural surroundings, are a growing concern for wildlife and biodiversity. The increased heat in urban environments, coupled with the loss of green spaces, can create inhospitable conditions for many species. Asphalt and concrete surfaces absorb and retain heat, leading to higher nighttime temperatures that disrupt the natural thermal rhythms of wildlife.

Wildlife adapted to urban environments often face a suite of challenges, including reduced habitat quality, food scarcity, and increased exposure to pollutants. Species that thrive in cities, such as pigeons and rats, are often generalists with broad ecological tolerances, while specialists and sensitive species are forced to retreat to cooler, greener fringes of urban areas or face local extinction.

To mitigate the impacts of urban heat islands on wildlife, cities are implementing green infrastructure strategies. Green roofs, vertical gardens, and urban forests can provide cooler microclimates and enhance biodiversity by offering refuge and resources for a variety of species. Cool pavements and reflective coatings on buildings can also reduce surface temperatures.

By prioritizing the creation and preservation of green spaces, urban planners and policymakers can help create more wildlife-friendly cities. These efforts not only benefit biodiversity but also improve the quality of life for urban dwellers by enhancing air quality, reducing energy consumption, and providing natural spaces for recreation and relaxation.
