Sustainable Landscaping
The Hidden Impacts of Gardens (See
the video)
Landscaping with native wildflowers and grasses
improves the environment. Natural landscaping brings a taste of wilderness to urban, suburban, and
corporate settings by attracting a variety of birds, butterflies and other animals. Once
established, native plants do not need fertilizers, herbicides, pesticides or watering, thus
benefiting the environment and reducing maintenance costs. Gardeners and admirers enjoy the variety
of colors, shapes, and seasonal beauty of these plants.

There are a variety of ecosystems
in the Great Lakes basin. Many of the plants found in these ecosystems can also thrive in your
yard, on corporate and university campuses, in parks, golf courses and on road sides. These native
plants are attractive and benefit the environment. Many native plant seeds or seedlings are
available from nurseries for landscaping. While these native plants are yours to admire in the
wild, they must remain in their natural setting to ensure that they can be enjoyed for generations
to come.
How to Get Started.
Everyone can include native plants
in their landscaping; from those with acres of land (e.g. corporations, universities), to those
with small urban lots, to those protecting a pristine ecosystem during a construction project.
There are some tips to know how to get started and what to expect while your wild plants are taking
root.
And while natural prairies require
fire for maintenance, mowing the native plants in your yard, or next to buildings, works just as
well. There is a toolkit for local governments to promote the use of native plants - individuals
may also find it useful! Be sure to read the wonderful law review article on municipal weed
laws.
Case Studies
Native plants are beautiful, hardy
and once established require less maintenance than a conventional lawn. The native flowers and
grasses also function much like a natural system, with diverse plants providing food and shelter
for a host of birds, butterflies and beneficial insects. Within the Great Lakes basin, and beyond,
people are incorporating native plants into their landscapes. There are successful examples of
native landscaping at corporations, universities, residences, schools, and other
places.
Ask Mr.
Wizard
The good news... many people are working hard to promote the use of native plants in landscaping.
The President is encouraging the use of native plants in landscaping on Federal grounds and in
Federally funded projects. The U.S. Environmental Protection Agency in Chicago has formed a Natural
Landscaping Workgroup dedicated to promoting the use of native landscaping.
In addition to developing and maintaining this Web
site, we are involved in other activities such as developing educational fact sheets and hosting
workshops about landscaping with native plants. And you can always talk to the wizard about
commonly asked questions.
Resources for Re-seeding. Find out
about native plant experts and resources for your Great Lakes State. Consult the following sources
for information about native plants and seeds. There is a feasibility study about turning abandoned
lots into native plant seed gardens written by The Nature Conservancy. And as always, there are
other great WWW sites which will help you down that path landscaped with native
plants.
Benefits
Landscaping with native plants
improves the environment. Native plants are hardy because they have adapted to the local
conditions. Once established, native plants do not need pesticides, fertilizers, or watering. Not
only is this good for the environment, it saves time and money. A native landscape does not need to
be mowed like a conventional lawn.
This reduces the demand for
non-renewable resources and improves the water and air quality. The periodic burning (or mowing
when burning is not practical) required for maintenance of a prairie landscape mimics the natural
prairie cycle and is much better for the environment. Landscaping with native wildflowers and
grasses helps return the area to a healthy ecosystem. Diverse varieties of birds, butterflies and
animals, are attracted to the native plants, thus enhancing the biodiversity of the
area.
The beauty of native wildflowers
and grasses creates a sense of place, both at home and work. The native plants increase our
connection to nature, help educate our neighbors, and provide a beautiful, peaceful place to
relax.
Reduced Use of
Pesticides
Since native plants have adapted to local conditions, they are more
resistant to pest problems. Sometimes individuals use non-persistent pesticides, which break down
into harmless components, before sowing native plant seeds to minimize competition from the weeds.
Once the native plants are established, pesticides are seldom needed.
Improved Air
Quality
Native landscaping practices can help improve air quality on a local
regional and global level. Locally, smog (ground level ozone) and air toxics can be drastically
reduced by the virtual elimination of the need for lawn maintenance equipment (lawn mowers, weed
edgers, leaf blowers, etc.) which is fueled by gasoline, electricity or batteries. All of these
fuel types are associated with the emissions of the following air pollutants: carbon monoxide (CO),
carbon dioxide (CO2), nitrous oxides (NOx), sulfur dioxide (SO2), VOCs (volatile organic compounds)
and air toxics such as benzene. Gasoline lawn and garden equipment, on average, produces 5% of
ozone-forming VOCs in areas with smog problems. This equipment also emits toxics and
particulates.
Regionally, the NOx and SO2
released from lawn maintenance equipment react with water in the atmosphere to form acid
rain.
Globally, native landscaping
practices help to combat global warming in two ways. Carbon dioxide (CO2) is a major greenhouse gas
and by reducing the use of lawn maintenance equipment, the associated CO2emissions are also
reduced. Native plants help to reduce the amount of CO2in the atmosphere by taking in CO2and
storing the carbon in the body of the plants, roots and soil. Native plants work much better than
traditional mowed grass as a carbon sink due to their extensive root systems and increased ability
to retain and store water.
Improved Water
Quality
In conventional landscaping, pesticides are often wrongly applied at
times when target insects are not vulnerable. Overuse and inappropriate use often kill beneficial
insects and other wildlife. Less than 10% of all insects are harmful to plants. Pesticides have the
potential to cause serious human health problems when not handled properly or applied according to
the label directions.
By eliminating or minimizing the
use of pesticides and fertilizers, these pollutants will not run-off into streams, lake, and bays.
This improves the quality of the water and the aquatic life in it. In healthy water systems.
natural controls, such as fish, frogs, and snails will help keep insect populations under control
and reduce algae buildup.
