Plant Native Plants to Support Local Environment, Wildlife

Earth Day is April 22. Every year, people around the world observe the day by helping1 to care for the environment. They carry out all kinds of activities in an effort to better the planet's health.

One way to support this goal is to grow plants native to your area. This helps wildlife like birds and insects that evolved alongside native plants. For many of these animals, plant pollen2 is their food.

Native pollinators often cannot recognize non-native plants as food. This means they do not collect the pollen or spread plants' seeds.

Planting non-native species creates so-called "food deserts" for pollinators including bees, birds, bats, butterflies and more.

Doug Tallamy is a professor of entomology at the University of Delaware. Entomology is the study of insects. He found that non-native plant species can harm the natural food chain, which can lead to a collapse3 of the environment.

"Plant choice matters," he said. "The plants we choose to landscape our properties (with) should be determined4 by how much life can live there."

Humans depend strongly on insects. Without them, we would have no flowering plants, which would harm the food web that supports important animals. Birds, for example, depend on plants for food and spread their seeds while keeping the populations of harmful insects down.

Insects support plants that provide oxygen, clean our water, capture carbon and add nutrients5 to the soil. That builds topsoil and prevents flooding. Without insects, the biosphere6 – the living parts of the Earth – would rot because of the loss of insect decomposers. Humans simply could not survive that, Tallamy said.

In addition to providing food and habitat for insects and other wildlife, native plants are able to grow easily and do not require much care. That means less watering and less fertilizing7. The situation is a win-win for gardeners and pollinators.
