The environmental benefits of a biodiverse property

Many homes today have grass lawns that lack native vegetation. The concept of a plain lawn on private property originates in seventeenth- and eighteenth-century Europe, where the wealthy had labourers or animals keep their lawns in a neat appearance. 

Today, grass lawns are the unquestioned standard, but apart from their tidy look, they offer few environmental benefits. In fact, they negatively impact local wildlife and often demand significant resources to maintain. 

In contrast, a biodiverse property filled with native plants, shrubs and flowers is a tangible alternative with meaningful benefits for the planet.

Benefits of a biodiverse property

One advantage of a biodiverse landscape is its ability to support pollinators and local wildlife. A plain grass lawn provides almost no food or habitat for creatures. Native plants, on the other hand, can provide nectar, seeds and shelter. A lack of biodiversity and general habitat loss prevent wildlife from thriving, so creating mini-ecosystems provides safe feeding and resting spaces.

Another benefit is its reduced need for water and fertilizer. Many yards in Canada use non-native turf grass, which requires more water and fertilizer to maintain. Estimates suggest that in Canada and the U.S., more water and fertilizer are used on lawn grass than on corn and wheat combined, while lawn care accounts for almost one-third of all residential water use in the U.S. Since native plants are well-adapted to local climate conditions, they don’t require fertilizer and use significantly less water compared to regular lawns. 

Biodiverse yards also play a role in carbon management. Native plants and trees can store more carbon than turf grass. Traditional lawns also rely on frequent mowing, and some gas-powered equipment can emit carbon dioxide, carbon monoxide, volatile organic compounds, nitrogen oxides and even cancer-causing agents like polycyclic aromatic hydrocarbons. Biodiverse properties both capture more carbon and require less maintenance overall, avoiding some of the emissions created by lawn care.

Lastly, biodiverse properties can add aesthetics that lawns cannot match. Native plant gardens can provide vibrant colours, textures and movement throughout the seasons. 

Green, biodiverse environments may also improve well-being by reducing anxiety and improving mood. They could even inspire neighbours to rethink their own landscapes. If more homeowners embrace biodiversity around their homes, communities can cultivate a greener urban environment.

Tips on getting started

Getting started with a biodiverse property can be simple with a few practical steps. 

A helpful first step is to research what grows best in your region and understand the conditions of the area you want to naturalize, including sunlight levels and soil type. Connecting with local experts, organizations and groups can provide support and resources both at the start and as the yard develops. The city of Toronto provides advice as well.

When choosing plants, look to native plant nurseries rather than big-box stores, as they’ll likely carry plants that are suitable to the local ecosystem. 

Avoid pesticides, as they can harm native plants and make it harder for them to get established.

With a bit of planning and the right support, transitioning to a biodiverse yard becomes a manageable and rewarding process.

Summary

Choosing a biodiverse property over a standard lawn brings clear environmental benefits. From supporting wildlife to reducing the need for resource-heavy maintenance, these landscapes offer more resilience in the face of growing climate pressures. By embracing a more natural yard, you’re not just changing your home’s appearance — you’re fostering a healthier community and planet.
