I just saw this blog post, by Kate Bradbury, a gardener who chose to remove the concrete from her front garden. She’s quite right to note that the concreting of front garden space is one of the blights of our towns and cities. People do it to create car parking space, but when this practise is widespread, the consequence is a loss of biodiversity, and increased flood risk.
It’s not a point she makes directly, but it is also one of the causes of hedges being lost in towns – on its own a hedge may not seem like a hugely important ecosystem, but the cumulative effect of many hedges is to create habitats for small creatures, insects and bees, wildlife corridors, and the absorption of CO2. The more hedges we lose the more of these effects we also lose.
I love the idea of removing the concrete from front gardens where it is practical to do so – and ideally I’d also want to see more hedges being planted to replace the ones we have lost.
