Fact sheet: Green infrastructure and biodiversity Global biodiversity has declined by more than a quarter in the last 35 years. Butterflies, birds and bee populations are dwindling and more than one in ten of the UK’s wildlife species are threatened with extinction. Change on this scale isn’t sustainable. Species must be wreathed in diverse and protected habitats if we’re to continue our long transaction of looking after the earth in exchange for food, energy, raw materials, clean air and clean water. Though it’s not practical for most towns and cities to create large areas of new land for green space, there is a lot that can be done to reconnect plant and animal populations through green infrastructure. Filling built-up spaces such as courtyards, roofs and walls with greenery not only provides shelter and food for different species but also helps to absorb dust and pollutants from the air, reduce noise, balance the water cycle and alleviate summer heat. The problem is these actions are often not coordinated or properly funded, instead popping up incidentally. This fact sheet, published by the international green infrastructure group PERFECT (for which the TCPA is a lead member), presents key research to demonstrate why investment in green infrastructure is essential for meeting the needs of future generations.
