The folks at Wildlife World put a lot of thought and care into beautifully designed structures that will attract beneficial insects and animals into your local ecology. They tested out everything from bat boxes to butterfly habitats in a 35-acre farm in the UK. Each one is sustainably built, with timber that’s FSC certified and sourced from well-managed forests and other elements (like plastic or metal) that’s recycled.
Along with bird feeders and bird baths, these habitats help provide learning opportunities, too. Scientific concepts like “pollination” and “the food chain” are way less abstract when you can see them come to life in your own yard.
