At the time of settlement,
grass-dominated ecosystems covered more than a million acres in Ohio. These
prairies evolved 5,000-8,000 years ago when Ohio’s climate was warmer and drier
than it is today. Even though the climate changed, Native Americans burned the
prairies which continually reset the process of succession that turns prairies
into shrubby woodlands in Ohio’s current moist climate. However, only a
fraction of Ohio’s prairies survived European settlement.
A 14-acre (5.4 ha.) sand
and gravel borrow-pit left from the construction of I-675 was hydroseeded in
1986 with prairie grasses, and plugs of forbs (non-woody, broadleaf plants) were
planted by hand. Undesirable species have been controlled primarily through
timed mowing and prescribed burns. Today, the prairie hosts nearly 150 native
plant species and increasing bird and mammal diversity.
Ohio prairies co-evolved
with fire, and controlled burns are an important part of MEEC’s management
strategy. Burning controls invasive, woody or otherwise undesirable species,
returns nutrients from standing thatch to the soil, and warms the soil in the
spring to encourage seed germination. Approximately one-third of the prairie is
burned each year to allow ample insect refuge.
