A recent study on urban indicators for UK butterflies shows how relevant and important campaigns such as ‘Let It Grow’ are. When researching the 28 different species of butterfly found in the UK, it became clear that for all 28 species the abundance trends were negative in urban areas. Butterflies are also in decline in the countryside, but at a slower rate than in the cities. The rate of decline in the urban setting can be attributed to various reasons, including the loss of green space, the neglect of park areas and an increased use of pesticide in gardens. The trend of turning lawns and flower beds into driveways and patios has also contributed to the increased decline.
There’s are a surprising amount of possibilities in an urban setting that can be used to encourage native species. From window boxes and balconies through to public parks and unused community spaces. All of it has potential to provide a home to local species of living things – if we get to work and provide the conditions that nature needs to work its magic. We therefore encourage you to investigate the possibilities of setting up let spaces in and around your institution, perhaps in cooperation with local botanical gardens or nurseries. Left spaces are great way to encourage the public to partake in the campaign and make a difference. Why not invite visitors to help create left spaces for World Biodiversity Day on 22 May 2017?
