Urban Nature-Strip Gardens Significantly Boost Biodiversity and Insect Populations
University of Melbourne researchers have discovered that planting native gardens on suburban nature strips can dramatically increase urban biodiversity. A study published in the Journal of Applied Ecology revealed that insect abundance in these areas increased sevenfold, and the number of species approximately doubled. The research, conducted across Merri-bek City Council in Melbourne's north, compared nature strips before and after the addition of habitat gardens. Lead author Dr. Philippa Bell highlighted that insect pollinators, such as bees, beetles, and butterflies, are crucial for ecosystems but are declining due to habitat loss. Traditional mowed lawns offer minimal shelter or flowering plants for these insects. The most significant positive response was observed among bees, directly correlating with the abundance and diversity of flowering plants in the gardens. Butterflies and beetles also showed positive, though more variable, responses.
