The term rewilding first appeared in the conservation world in the 1980s with a continental-scale vision to protect large tracts of wilderness and connect these areas with migration corridors. Biologists recognized the important role of wide-ranging large carnivores in maintaining the health of the whole landscape by controlling populations of grazing animals that they prey on. Yellowstone National Park is a case in point. After a century of wolves being absent, the landscape had been severely overgrazed by elk. In 1995, wolves were reintroduced into the park and, within a decade, vegetation returned, and a diversity of wildlife now thrive.
At Wild Seed Project, we consider rewilding to be not just for the large wilderness areas or charismatic megafauna like wolves. We focus our efforts on actions that people can take right outside their door. Rewilding is also a deliberate shift from human-centered, intensively managed landscapes to humans sharing their lands with the rest of nature. It is an intentional practice of restoring native plants in urban, suburban, and rural landscapes to reverse habitat loss, support ecosystems services, and bring nature back into our daily lives.
Rewilding begins with recognizing native plants as the basis of the local food web. Native plants are essential for populations of insects that in turn support birds, which serve as the bellwether of ecological health and resiliency. Recent research by University of Delaware biologist Doug Tallamy demonstrates that for a place to support a diversity of life, native plant species must represent at least 70% of the biomass in the landscape. Below this critical threshold, food webs collapse and habitats unravel.
Seventy percent native plant biomass is a clear goal to strive for in all of our landscapes. But what does that look like, and how do we make that happen?
Below are collections of images to help you visualize how you might rewild a wide variety of places.
When reimagined through the rewilding lens, the vast expanses of (rather sterile) pavement and lawn in cities and suburbs can be transformed into habitat for both people and wildlife and help rekindle the sense of wildness and connection to the natural world that we crave.
Native species of oaks, cherries, willows, birches, poplars, and elms are found to support the widest variety of life. Since trees produce such a large volume of leaves that insects rely on as a food source, they are in turn essential to feeding songbirds with a bounty of protein-rich caterpillars. The sheer amount of vertical mass we’ll get from planting native trees will carry us toward our rewilding goal of 70% native plant biomass in leaps and bounds.
Rather than letting resource-sucking lawns dominate the bulk of our yards, they can instead be used sparingly and purposefully, such as for recreation or as pathways that convey us through the landscape. Urban and suburban lawns can be mostly converted into meadows, or other types of layered plantings with trees, shrubs, and groundcovers to feed pollinators, birds, and other wildlife.
Restoring native plants is not just about planting, but also preserving existing native vegetation. Sometimes mowing less or removing invasive plants is all that is needed to encourage native plants to make a comeback and return these landscapes to the vibrant species-rich places they once were.
Rewilding can look intentional and ornamental while still providing essential ecosystem services. Well-defined edging and beautifully arranged textures, layers, flowers, and fruits set gardens apart from more wild spaces. They are made more ecologically functional by adding a diversity of native plants and using more wildlife-friendly practices, such as eliminating the use of pesticides, fertilizers, and keeping natural leaf litter intact. How we manage our native plantings will determine whether we can sustain and support the life-cycles and successful reproduction of butterflies, moths, bees, birds, salamanders, frogs, and many more organisms.
You don’t need land of your own to be a rewilder! Adopt a street tree to care for, tend a sidewalk hellstrip, display native containers on your stoop, plant a window box with natives, encourage your favorite restaurant or place of business to add native plants to their outdoor spaces, or make your community garden plot into a safe haven for butterflies and birds.
It can be intimidating to talk to your neighbors, friends and family about the need to plant natives for habitat creation, and it can be even more difficult to ask others to change their landscape practices. One way to spark conversation in a non-confrontational way is to put up a yard sign that offers insight into the work you are doing. Curious passersby will stop and ask questions if they like what they see. You can start by inspiring others through your example.
As we face the unprecedented urgent and entwined challenges of the climate crisis and biodiversity loss, you can be part of the solution when you pledge to rewild. When you take the pledge, Wild Seed Project will share practical tools and resources that will guide you through rewilding. This is a holistic process of restoring native plants to the landscape, shifting away from harmful landscape practices, and engaging your community in this ongoing cooperative effort. We hope to inspire a movement to build momentum toward our shared vision of bringing nature back to where we live.
