Shrink the lawn. Plant diverse native species instead.
Tallamy says if each suburban home cut its lawn in half and replaced it with native flowers, shrubs and trees, we’d create a rich, bio-diverse "Home-grown National Park" 20 million acres in size.
Plant “keystone species.”
Among our area's most ecologically productive species —those that are best at making the caterpillar food that drives our entire food web — are native oaks, willows, birches, poplars, maples and cherry trees, as well as goldenrods, asters, sunflowers, strawberry and Joe-Pye weed.
Cut light pollution to protect moths, pollinators and other valuable insects.
Don’t blow away your leaves. Keeping leaf litter allows caterpillars to complete their development and become pollinators or food for birds.
Most species (94%) drop from trees or plants and pupate in the soil, or in cocoons in leaf litter. So "leave the leaves" when they fall, and create native flower beds around your trees instead of surrounding them with grass or purchased wood mulch.
