Why is this area so special?
The Oak Openings Region of Northwest Ohio is a globally rare
ecosystem declared by the Nature Conservancy as “One of
America’s Last Great Places”.
The region is much more than just Oak Openings Preserve
Metropark.
The Florida Everglades is on the same list as the this region. Who
would have thought a sandy stretch of land in Northwest Ohio would
be included with such prestigious company as the Everglades? They
are both included on the Nature Conservancy's list of
America’s Last Great Places.
It is home to more endangered native plant species than any other
place in Ohio. More than one-third of all Ohio’s rare plant
species can be found here.
Consequently this part of Northwest Ohio has been a favorite place
for botanists from all over the country (and world) to study the
unique animal life and rare plants that grow here.
A recent success story of the Oak Openings is the reintroduction of
the Karner Blue Butterfly. It wasn't seen here since the late 1980s
but is now back.
Where is it?
The Oak Openings Region is in the western portion of Lucas County,
stretching in to portions of Fulton and Henry counties at the south
end. To the north is extends almost to the Ohio-Michigan line It is
a band of sandy soil that is approximately 22 miles long and varies
from 3 to 5 miles wide.
How the region was formed?
The Region was formed during the last ice age. When the glacier
that covered this part of the state began to melt it created a very
large lake. The lake has since been named Lake Warren.
As the lake waters receded the old beaches and sand dunes were all
that remained.
Click Here for an interesting paper that discusses how the region
was geologically formed. It was written by some researchers at the
University of Toledo.
Land Characteristics
< The sandy soil left by the lake helped to create one of the
most unique ecosystems and habitats in the state of Ohio as well as
globally. The depth of the sand is anywhere from inches to 20 feet
deep. Beneath the sand is a thick layer of blue clay that water
cannot penetrate.
That’s why in some areas there is standing water for much of
the year and in other areas it is almost desert-like. On the sand
dunes the water quickly filters through the sand down to the clay
layer.
Where the sand is thin and the clay is only inches below, there is
standing water and swampy areas for much of the year. It is only
during the warm, dry days of summer and fall that the water dries
up.
You will see high, dry sandy areas which quickly give way to wet,
swampy areas. This transition is in a matter of feet. You can be
standing on top of a sand dune looking down at a swamp.
The entire Oak Opening Region is like this, yellow sand dunes
giving way to swamp forest or wet prairie.
These unique characteristics are the reason so many rare plants and
animals live here.
Yellow Sand Dunes
The dry, hot sand dunes are not very hospitable places for most
plants to grow. The plants that do grow in that kind of habitat are
unique. Many of them don’t grow any where else in Ohio.
The plants that grow on the sand dunes have adapted to the extreme
conditions. Plants like the prickly pear cactus thrive in the hot
sand. That’s because they have long roots that work their way
down to the water table below.
Other plants like wild lupine and bluestem grasses were once quite
abundant. Open prairies full of colorful wild flowers, tall
grasses, and sparse oak trees must have been quite a sight.
Black oak is the most prevalent oak tree that grows here. It likes
the sandy soil and has adapted to the conditions.
Wet Swampy Areas
The same holds true for the wet, swampy areas adjacent to the
dunes. The wet prairies are also home to many rare species of
plants and animals not found any where else in Ohio.
The swampy spots come in a couple different forms. Some swampy
areas are covered with forest. These areas are swamp forest areas
(appropriately named) and are typically full of pin oak trees,
maple trees, black tupelo, and others.
There are still many swamp forest areas scattered throughout the
region. They can be found on many privately owned wooded lots as
well as parks and preserves.
They have remained over the years since the land was too wet to
farm in the early days. Land owners didn’t bother to remove
the trees.
Other swampy locations are open areas and considered to be wet
meadows or wet prairies.
The best example of a wet meadow / wet prairie is Irwin Prairie
State Nature Preserve. This prairie once extended for miles across
western Lucas County. Only a small portion of of the original
prairie remains today.
The Name Oak Openings
The name Oak Openings comes from early settlers who came through
here on their way west.
After spending horrid days and nights trudging through the deep,
thick muck of the Great Black Swamp they would have made their way
to this area. What a welcome change the dry, open ground must have
been.
The sand dunes would have had oak trees (mostly black oak) growing
sparsely on the sand dunes.
Growing below the oak trees would have been sedge grass and little
bluestem grass. These “openings” were referred to the
settlers as Oak Openings.
Restored oak savannas still have this characteristic. They can be
seen at Oak Openings Preserve, Kitty Todd Preserve, Secor
Metropark, and some private residences.
Native Americans
Humans have played a role in the Oak Openings Region for thousands
of years. The Native Americans helped preserve the prairies and
black oak savannas.
The natives saw the benefit of fire to the landscape. They saw that
it was a critical component to maintaining the natural habitat.
Fire would keep invasive plants and other brushy, woody plants from
taking over the oak savannas.
With periodic fire the native prairie species, like wild lupine,
could thrive without being choked out by larger woody plants.
Native Americans would set fire to the prairies to maintain food
sources like wild blueberry. The open savannas attracted wildlife
which made hunting easier. Food was more abundant.
Development of the Oak Openings
It wasn’t until the Europeans began settling this area and
the natives were pushed out that the practice of fire suppression
began.
When management of the land was no longer practiced the invasive
plants began to take over. Over a period of time the savannas
became overgrown. The grasses and wildflowers were choked
out.
The rare ecosystem that had been thriving for thousands of years
was starting to disappear.
The development of Northwest Ohio lagged behind the rest of Ohio as
a result of the Black Swamp. This just wasn’t a great place
to be in the early to mid 1800s. Standing water was a breeding
ground for mosquitoes. Malaria was rampant.
As the area became more populated in the late 1800s and early 1900s
drastic changes began to take place in the Oak Openings. The main
objective of settlers was to create as much tillable farm land as
possible. Standing water was in the way.
Hundreds of miles of ditches were dug in Lucas County to drain the
water. Ponds were created. The wet meadows and prairies were filled
in. Residential homes were built, and then commercial development
began.
Edwin Moseley
In the 1920s a naturalist from BGSU by the name of Edwin Moseley
began studying the Oak Openings Region. He was the first one to
define the area known today as the Oak Openings.
There are other sandy areas in Northwest Ohio that can be
considered similar habitats. These are also as a result of the
different stages of Lake Warren receding. Some are near Bowling
Green. Others are further west in Fulton County.
But the area known as the Oak Openings Region today is the area in
western Lucas County defined by Moseley.
He began studying and writing about the unique and rare plants and
animals found here. He published many of his papers worldwide. Soon
after, naturalists from around the world began coming to the Oak
Openings Region to study the unique plants and animals.
It is Disappearing
Since Edwin Moseley’s work, the habitats of the Oak Openings
Region have drastically been reduced in size and numbers.
Development continues. The Toledo airport destroyed hundreds of
acres of Oak Openings Region land in the 1950s. Residential
developments continue to destroy prairies and wet meadows.
The rare plants and animals that can only be found here in the
state of Ohio continue to be at risk of disappearing forever.
Awareness
The destruction of the Oak Openings isn't necessarily being done
deliberately. Many people just don't know what it is or why its
special. A rare plant to some is a weed to others. A sand dune
capable of sustaining a globally rare habitat is also a nice, dry
building site for some.
Fortunately the number of local residents who are familiar with the
Oak Openings continues to increase. Local programs by the Toledo
Metroparks, Toledo Zoo, and other local organizations continue to
promote awareness.
The local Nature Conservancy office, located at Kitty Todd
Preserve, operates a land registration program for home owners in
the Oak Openings Region. This program recognizes home owners who
make a conscious effort to conserve all or a portion of their
land.
The return of the Karner Blue Butterfly and Wild Lupine to Kitty
Todd and Oak Openings Preserve has done a lot to increase local
awareness.
Hopefully man and nature can find a balance and what is left of the
Oak Openings Region will still be here for future
generations.
Congrats to Mighty Mo for the FTF
