Restore your own backyard
By David Beach
The guy from the tree company thought he could save the paper birch in my front yard. The tree was suffering from two pests: the bronze birch borer and the leaf miner. But a regimen of pesticide injections and sprays could control the problems, he said. It would be a shame to lose such a decorative tree.
The paper birch, with its lacy white bark, had been planted years ago by a previous owner who no doubt had noble landscaping intentions. But it was a cool-weather tree out of its natural range. Ohio's hot summers placed it under too much stress, made it too susceptible to pests. It was doomed to die and early death unless I agreed to pay for perpetual chemical fixes.
In the end, I decided to accept nature's verdict. I told the guy from the tree company to cut the birch down. I replaced it with a hardier tree that's adapted to local conditions.
It's the kind of decision faced by everyone who is the steward of a piece of land. How far do you go to impose your own will and landscape prejudices on your yard? Do you follow the 'barefoot grass' admonitions of the lawn care companies, or do you allow natural processes to run their course?
In recent years, it seems more and more people are choosing to err on the side of nature. Some are concerned about the health dangers of pesticides used to poison nature into submission. Others want to turn their artificial, monoculture lawn into a more diverse, natural habitat. They realize that, while urban or suburban land is usually so disturbed that is must be 'managed' in some way; the management doesn't have to be toxic. And the resulting yard can contribute in many ways to the larger ecosystem of the region.
"It starts off with homeowners realizing that they are just temporary custodians of this habitat, and they can help restore it or they can blindly follow the landscape style of the guy down the street with a lawn and a few shrubs," says Brian Parsons, natural areas coordinator at the Holden Arboretum in Kirtland.
"If you look at each blade of grass in your yard as an introduced plant species that has displaces a native species, then you can begin to sense the magnitude of change we have made in the name of 'progress,'" he adds.
Gardening writer Sara Stein comments in her book, Noah's Garden: "Suburban development has wrought habitat destruction on a grand scale. As these tracts expand, they increasingly squeeze the remaining natural ecosystems, fragment them, and sever corridors by which plants and animals might refill the voids we have created. To reverse this process, to reconnect as many plant and animal species as we can to rebuild intelligent suburban ecosystems, requires a new kind of garden, new techniques of gardening, and, I emphasize, a new kind of gardener."
In this spirit, here are a few basic steps we can take to restore our yards and the larger ecosystems of Northeast Ohio:
The cooler north and east sides of a house can become woodland meadows. The south and west exposures can feature prairie species. You can find examples to follow in parks throughout the region.
One problem for the casual gardener is finding sources of native plants. Restoration purists scoff at all-purpose, wildflower seed mixes (a "meadow in a can") sold by national retailers. They say it's important to collect seeds of native plants growing within 100 miles or so. Only then can you be reasonably sure that the plants' genes have evolved in response to the specific climatic and ecological requirements of the region. Local nurseries don't often sell such native plants, leaving most gardeners to depend on nurseries elsewhere in the eastern United States that sell seed or propagated natives.
Ultimately, the goal should be to create an authentic, regional landscape aesthetic, just as some parts of the country have regional cuisines or styles of architecture, Parsons says.
"Right now, we have no landscape style of our own," he says. "Everyone's got this exotic landscape. There's no sense of place."
"We need to consider ourselves as the temporary custodians of land which is home to hundreds of native plant and animal species our own lives are brief. But the consequences of our actions can far outlive us. After we move on, our plants stay put, and they can remain for 100 years."
