How urban bushland improves our health and why planners need to listen
Urban bushland has health benefits beyond being a great place to go for a walk. It filters our air and water, helps cities avoid extremes in temperatures, and is linked to lower rates of chronic disease.
But these and other health benefits are virtually never accounted for in local and state land development processes.
Urban planners need to consider these health benefits when making decisions about the future of our cities.
What do we mean by urban bushland?
Urban bushland ranges from a bush park of native trees, to wetlands – in fact any native vegetation characteristic of the local region. With its undisturbed soils and associated wildlife, urban bushland is more diverse than other types of green spaces in our cities, like parks. So it adds significantly to neighbourhood biodiversity.
The more unfragmented the landscape, or unaltered the bushland, the more likely it will be to retain its biodiversity. Hills, watercourses and gullies, or a mixed forest, have greater biodiversity than flat land or a plantation of trees. Landscapes that change by the season add to that diversity.
The health benefits of green spaces (and urban bushland) partly comes from this biodiversity.
In cities, health benefits work at two levels. Not only do local residents receive health benefits when they use urban green spaces, the wider urban population also feels the health effects.
