Protecting biodiversity starts… in your own backyard!
When we think about protecting biodiversity, we often picture ecologists deep in tropical rainforests, rare animals in faraway lands, or vast nature reserves on the other side of the world.
So how can ordinary people get involved in protecting living species? The answer is probably much closer than you think. Literally. In our backyards, our gardens… and even on our balconies.
Because biodiversity isn’t protected only in national parks.
It’s also protected through small everyday actions, and helping local wildlife is much easier than most people realize.
Blessed be imperfect lawns
For decades, the image of the perfect yard was a large, perfectly trimmed green lawn with no leaves, no weeds and no insects. The problem is that for bees and many other tiny creatures, a yard full of grass is basically a green desert.
A short, uniform lawn offers very little food, very little shelter and almost no habitat for insects. Yet these tiny animals play an enormous role in our ecosystems. Bees, bumblebees, butterflies and other pollinators allow many flowering plants, including numerous fruits and vegetables we eat every day, to reproduce.
In fact, it’s estimated that one bite out of every three we consume depends on pollinators.
Canada alone is home to more than 800 native bee species. Unfortunately, many populations are declining due to habitat loss, pesticides and climate change.
Thankfully, a few flowers can already make a real difference.
Specialists recommend incorporating more native plants into landscaping. These plants have evolved alongside local wildlife for thousands of years. Insects recognize them, feed on them and sometimes depend on them entirely to complete their life cycles.
Ideally, gardeners should choose species that bloom at different times throughout the season, from spring through fall, to provide pollinators with a continuous food source. Even a few flowerpots on a balcony can help.
And most importantly, there’s no need to turn your yard into a jungle.
Often, simply leaving a small corner a little more natural is enough to create a valuable refuge for wildlife. In recent years, many municipalities have even encouraged residents to mow less frequently. Behind this movement lies a very simple reality: spontaneous flowers, taller grasses and slightly less “perfect” spaces quickly become feeding grounds for insects.
This new way of thinking about green spaces sometimes requires a shift in perspective. A yard that is slightly less immaculate can become far more alive.
Precious amphibians
And pollinators aren’t the only ones benefiting from these small actions.
Amphibians such as frogs, tree frogs and salamanders are among the species most sensitive to environmental disturbances. Their highly permeable skin makes them especially vulnerable to pollution and pesticides. Yet they, too, can find refuge close to our homes. Many amphibians are valuable allies for gardeners, helping control unwanted insects in vegetable gardens.
A few dead leaves left on the ground, some branches piled in a shady corner or a small damp area can become essential to their survival. What may seem insignificant to us, a simple pile of leaves, can actually be a five-star hotel for a salamander. In highly manicured gardens, where everything is cleaned up and trimmed to perfection, these animals struggle to find places to hide, retain moisture or escape the heat.
Welcoming bats
Then there are bats. Often misunderstood and sometimes feared, they are nevertheless among our greatest allies against pest insects. A single bat can capture thousands of insects in one night, making them some of the most effective natural exterminators in the animal kingdom.
But bats face many challenges as well: habitat loss, disappearing mature trees and disease. Here again, a few simple actions can make a difference. Installing a bat box, preserving older trees or reducing excessive outdoor lighting can greatly improve their environment.

In the end, protecting biodiversity doesn’t necessarily mean always doing more. Very often, it simply means leaving a little more room for nature by accepting, for example, that one corner of the yard may be a little less controlled.
Because a backyard can be much more than just a decorative space. It can become a corridor for pollinators, a refuge for amphibians or a feeding ground for birds. And when thousands of people make these small changes at the same time, the impact becomes enormous.
