Lawn more like yawn!
Lawns are a major biodiversity risk, found in almost all gardens in Australia!
Not only do they use a large quantity of water, maintenance and fertiliser, they are hostile to animal and insect population. Lawns impact the local soil pH, structure and temperature changing dramatically from the typical local norm. While grass is better than concrete and asphalt, they don't lower the local temperature nearly as much as gardens and trees. Lawns create what is called the edge effect, which is linked to habitat fragmentation, causing increased exposure to the local fauna to harsher weather, increasing their risk and reducing population numbers.
You as a gardener can help reduce this impact! By reducing your lawn area and continuing to plant gardens you are helping all of your local fauna, big and small.
