Planting for Nature

Doug Tallamy is a well-known advocate for native plants. In his book “Bringing Nature Home: How you Can Sustain Wildlife with Native Plants,” he discusses strategies for planting landscapes that attract insects, birds and other animals who have developed specific relationships with native plants. As an entomologist, Doug is particularly interested in attracting herbivores like caterpillars, which serve as a vital food source for birds and mammals and provide the foundation for a healthy ecosystem.

Monarchs depend on milkweed for survival.

Monarch butterflies, for example, depend on native milkweed plants as their sole food source. With the number of milkweed plants in decline, Monarch populations have declined as well. With nature suffering around us, what’s a homeowner to do?

There are a number of strategies you can act on and some of them might surprise you. Most people think of adding native perennials to attract butterflies and bees as a first step. In terms of positive impact on the environment, priority tasks for homeowners who want to be more sensitive to our natural world include removing invasive species; planting native, disease resistant woody ornamentals (trees and shrubs); and reducing lawn space.

Eliminating Invasives

Not all the species within a genus are invasive, but many are. Buddleia davidii is on the invasive list, but some of the newer cultivars are sterile. The same is true for Berberis, Ligustrum, and Euonymus. With over 3300 documented invasives in North America, I can’t list them all. Consult with your state’s department of conservation and natural resources or your local extension office for additional information on invasive species. Pennsylvania maintains a comprehensive list of the current offenders. You can also research Invasive.org for extensive information on invasives in the United States and learn about methods for control. We need to eliminate invasives on our own properties to help mitigate their consumption of our forests and other natural habitats.

Invasives like this barberry consume our forests and destroy the native landscape.

Planting for Impact

In a recent online interview, Doug Tallamy informed the audience that a Chickadee needs access to 6000 to 9000 caterpillars to raise a single brood. Even the red fox we love so much depends on insects, which make up 25% of its diet. A single perennial won’t support that kind of food source, but a white oak would help. An oak supports 557 species of caterpillars. In your own landscape, start your native plant transformation by installing trees and shrubs. In an environment where rampant construction and pests like the Emerald Ash Borer are destroying the woodlands, one of the best things you can do for our ecosystem is to plant a native tree. For additional information on the most suitable trees and shrubs, I recommend Garden for Wildlife, created by the National Wildlife Federation and Native Back Yards. Both sites offer helpful information. Another great resource for attracting birds to your home garden is the Audubon Society’s native plant database.

Chickadees and other birds need our help to provide the food sources they need to raise their young.

Limiting Lawn

Many homeowners are very proud of the expansive, emerald-green lawns and go to extreme measures to keep them weed free and perfect. But a pristine lawn does nothing for the ecosystem except pollute it with chemicals. A better approach is to reduce your lawn space by 50% and install plants instead.

Cedar waxwings spent three days frolicking in my water feature.

Once you have addressed the priority tasks in your garden, keep going. Install a water feature to simulate a wetland environment. Plant drifts of native perennials to attract pollinators year-round. Most of all, notice the change in nature’s response. In my own garden I have witnessed a flock of Cedar Waxwings in my water feature, welcomed hundreds of other birds and pollinators, and seen a lot of mammals trapsing through the garden. I couldn’t feel more at home in my little wildlife preserve and I wish the same for you. Don’t let me keep you. I know you have some research and planning to do, and I fully support those efforts.
