The rise of ‘blandscaping,’ and why not all green space is created equal

This copy-and-paste approach to landscape design is the ecological equivalent of gentrification. And it needs to stop.

With skyscrapers climbing ever higher and unoccupied city areas increasingly scarce, demands on urban space are increasing. Making the most out of this space requires a careful balancing act between short-term human needs and long-term planetary benefits.

All too often, attempting this balancing act ends up in “blandscaping,” the practice of creating virtually uniform green spaces that are devoid of local character or distinctiveness. These bland landscapes arise when urban green spaces are designed with an entirely human focus: making them attractive to look at and easy to manage, but containing almost none of the valuable biodiversity that would otherwise have occupied the space.

Rather than tailoring the built environment to the local landscape, blandscaping uses what might politely be called a “copy and paste” approach. Globally, similarly generic designs abound, often using the same materials—and the same species—across vast geographical areas.

Like a tidal wave of uniformity, this approach sweeps biodiversity aside. Just as the monocultures created by intensive single-crop farming have threatened a huge range of plant and animal species, blandscapes render formerly diverse ecosystems identical by removing the variety of habitat features—including different soil types, complex plant structures, and unique hydrological patterns—that allow nature to flourish.

The creatures that blandscaping benefits most are “urban generalists”: the kind of hardy animals that thrive almost anywhere, such as feral pigeons and house mice. These species prosper at the expense of others that require more specific habitats, including hedgehogs and rarer pollinators like the pantaloon bee.

The danger of blandscaping

Blandscapes are often celebrated for increasing biodiversity simply because they’ve replaced slabs of tarmac or concrete with something green. Typically focusing on evergreen hedges, exotic and complex flowering plants, lots of grassy areas to sit or walk, and a covering of wood chippings, or bark, to suppress undesirable plant species, blandscapes can at first glance appear to provide a home for nature.

When the starting point is a square of sterile gray, adding any greenery might seem to be the best option. But the “any green is good” mantra misses opportunities to rewild our urban landscapes with the complex mosaics of nooks and crannies that help nature proliferate.

Far from being praised, blandscaping should be seen as the ecological equivalent of gentrification. Resident communities are being displaced under the guise of revitalizing the area, and what remains is a habitat suitable only for the elite few rather than the many.

Throwing generic plants and soil into a landscape design is a form of ecological cleansing. Local species face little chance of survival when natural habitat diversity, which provides the range of resources needed to support all kinds of nonhuman communities, is removed.

The irony is that many of the postindustrial “wastelands” being blandscaped, such as the rapidly regenerating landscape of the Royal Docks, were much richer in the very biodiversity that we need to be protecting predevelopment. In fact, some of the most biodiverse habitats can be found on unmanaged postindustrial sites like Canvey Wick, in Essex, where nature has been allowed to thrive by itself. Sites like these offer a far better blueprint for urban design than the cookie-cutter approaches typical of many city spaces.

When we confine ourselves to blandscapes, we miss out too. From birdsong to butterflies, proximity to nature carries a host of benefits. Why should we settle for unimaginative and exclusory urban environments, when the natural world has so much more to offer?

Ecomimicry: design inspired by nature

An emerging approach to urban design—ecomimicry—recognizes the many lessons we can learn from the self-organizing systems of the natural world. In the words of designer Van Day Truex, when it comes to design, Mother Nature is our best teacher.

An ecomimicry approach starts with reading the local landscape like a book. By getting to know how different parts of a regional ecosystem intertwine, urban designers can integrate the ecological functionality that already exists in the landscape—like an abundance of pollinators, natural flood defenses, and food—into what they build.

Examples include covering roofs in locally typical vegetation that can feed animals and humans, or building around, not over, coastal treasures like dunes and mangrove forests, and incorporating habitat features of these landscapes into the new surrounding landscaping to increase habitat connectivity, ecosystem service provision, and resilience.

With an awareness of nature’s importance gaining momentum, increasing numbers of entrepreneurs are developing nature-based designs with ecomimicry at their core. Welcoming biodiversity back into our urban areas can reconnect communities with nature, supporting equal access to the social, physical, and psychological benefits nature provides us for free.

Our project, EU Horizon 2020 Connecting Nature, is working with cities worldwide to explore how to bring nature back into urban landscapes. We’re helping tease out the trade-off process between human and environmental needs that city planners face when trying to integrate nature. In doing so, we hope to introduce ecomimicry approaches to the mainstream and to restore cities to the biodiverse glory of the landscapes in which they lie.

If ecomimicry is to gain a foothold in our landscapes, three things are necessary: We must involve local ecologists who understand the unique complexities of the habitats being altered. We must ensure that the inherent value of all creatures is reflected in our approach to urban design. And we must embed this approach into policy so that it lasts for years to come.
