Letting parts of your garden grow wild with long grass can increase butterfly numbers by up to 93% and attract a wider range of species, according to new research from leading wildlife charity Butterfly Conservation.   The study provides the first scientific evidence that having long grass in your garden increases butterfly abundance and diversity. Creating such wild spaces may help to reverse the decline of these beautiful insects.  The research is great news for gardeners and non-gardeners alike, proving the free and easy action of letting an area go wild can make a positive impact for butterflies.

The potential to provide wild spaces for butterflies and moths to thrive is huge. Gardens make up more than 728,000 hectares in Great Britain.   If each of these gardens had a space that was allowed to go a little wild, with grass growing long, it would make a huge difference for butterflies and moths, providing spaces for them to feed, breed and shelter.   While the research specifically studied gardens, the benefits to butterflies of long grass and wild spaces are likely to extend beyond the garden gate. Public green spaces such as parks, school grounds, allotments, and road verges, could also provide vital spaces for wildlife, and enable more people to see more butterflies if allowed to go a little wild.  Read how to create your own wild space on this page.
