Nature Strip Gardens Attract 7x More Pollinators

A recent study in Melbourne has found that nature-strip gardens can be a paradise for pollinators, attracting seven times more insect pollinators and twice the variety of species compared to untouched nature strips. The study, conducted in partnership with the City of Merri-bek, involved 14 residents and used native plants known to feed or shelter local insects.

The study's findings are significant, given that nature strips make up more than one-third of public green space in Melbourne. Councils across Greater Melbourne already allow gardening on nature strips, some with permits, and many encourage residents to use low-growing native plants to support biodiversity and soften the streetscape.

The research used a before-after-control-impact design to compare insect biodiversity before and after each garden was installed. The gardens were planted with native plants known to feed or shelter local insects, following the council's nature-strip guidelines. The results showed that nature-strip gardens can support a wide range of insect pollinators, including native bees, beetles, and butterflies.

## Why it matters The decline of insects worldwide has significant impacts on ecosystem functions, including pollination. By transforming nature strips into gardens with native plants, residents can contribute to urban greening and biodiversity support. This approach can also help to soften the streetscape and provide resources for urban animals that rely on complex vegetation for food, nesting, and shelter.

The study's findings have implications for urban planning and biodiversity conservation. By harnessing the potential of nature strips, cities can create a network of green spaces that support local wildlife and promote ecosystem health. As the world faces the challenges of insect decline and urbanization, the humble nature strip can play a surprising role in supporting the health of our ecosystems.
