Urban Rewilding: explained
Frequently asked questions
The Violet Crown Trail at Barton Creek Greenbelt, Austin. Urban trail networks like this one connect neighborhoods directly to restored greenbelt habitat.
Urban rewilding is the practice of restoring biodiversity and natural processes within towns and cities. It is one expression of the broader rewilding movement, applied to urban environments. It ranges from city-scale projects like creating wildlife corridors, daylighting buried rivers, and planting native street trees to individual actions like replacing lawn with wildflowers, installing a wildlife pond, or leaving a corner of your garden wild. The core principle is reducing human intervention and giving nature space to return.
Start by reducing tidiness: let a corner grow wild, stop using pesticides, and remove paving where possible. Plant native wildflowers and shrubs that provide food for pollinators and birds. Install a small wildlife pond, even a buried washing-up bowl can help. Create a log pile for beetles and hedgehogs. Make a hedgehog hole in your fence so wildlife can move between gardens. Every small action connects to a larger urban ecosystem.
A xeriscaped front yard: prickly pear, agave, and native flowering shrubs replace turf grass with habitat that actually supports pollinators.
Yes, it can have a significant impact on biodiversity. Research across UK and European cities finds that connected networks of rewilded gardens and green spaces support surprisingly high biodiversity. Urban areas can harbor more native bee species than intensively farmed countryside. Studies show that even small patches of native wildflowers increase bumblebee abundance by up to 89%. The key is connectivity: isolated patches are less effective than linked corridors.
A wildlife corridor is a connected strip of habitat that allows animals to move safely between larger green spaces. In cities, corridors can be formed by linked gardens, street trees, railway embankments, river banks, and parks. Without corridors, urban wildlife populations become isolated and inbred. GPS tracking studies show that connected urban green networks dramatically increase animal movement, foraging range, and genetic diversity.
The San Marcos River, Texas. Urban rivers like this one, kept clean and tree-lined, function as some of the most effective wildlife corridors a city has.
