Gardens are human-made habitats, but they mimic the woodland edge, so they also hold on to water, slow down wind, create shade and provide food and homes for wildlife. In cities they can absorb pollution and help reduce urban temperatures. Crucially, they also link together to form vast corridors that connect other ecosystems (the woodlands, peatlands and other terrestrial systems mentioned above), enabling species to move between them, potentially giving them space to adapt to climate change. Of course, they also absorb and store carbon – in lawns, in the bark of trees, in the sludge at the bottom of garden ponds, in soil, in leaf litter and compost.
