Greenspace Gems recognizes and celebrates natural areas in the Green Umbrella region with outstanding scenic value, biological diversity, scientific importance, or historic interest. By telling the stories of these protected places, we hope to grow public support for greenspace conservation and the organizations who are leading this work in our region.

Greenspace Gems were selected by a team of conservation experts to reflect unique natural sites in our region. The team strives to highlight places that represent the geographic spread of Green Umbrella's 10-county region while showcasing a diversity of interesting features: from geology to biodiversity to plant communities to history. Each site tells a story of people taking action to protect a natural resource.


Oxbow Nature Conservancy

Dearborn County, Indiana

Oxbow Lake formed in 1847 when floodwaters of the Great Miami River cut a new channel, isolating a meander in the abandoned riverbed. The lake and surrounding floodplain support a wetland/farmland population of more than 290 species of birds, 65 species of butterflies, 472 species of vascular plants, and 66 species of fish. Thousands of migrating birds pass through each year.

Protected by Oxbow Inc. 

In 1985, when industrial development threatened Oxbow Lake and adjacent lands, Oxbow, Inc. formed as a land-trust conservation organization and began purchasing the property. The organization now protects 2.5 square miles of the floodplain.

The protected property lies near the confluence of the Great Miami and Ohio Rivers. From exit 16 on I-275, travel 200 yards south on U.S. Route 50, turn left onto the road between the Shell/Subway and Waffle House, right at the end of the road, and left into the Oxbow, Inc. property.

Glidewell Mound

Franklin County, Indiana

The Glidewell Mound is one of the surviving Native American earthworks in our region. Adena people built this oval-shaped mound on a promontory overlooking the Whitewater Valley about 2100 years ago. Later cultures also used it. Excavations beginning in the late nineteenth century found several Hopewell burials and copper grave goods. The earthwork is located about mid-way around the two-mile “short loop” Glidewell Trail in the Mounds State Recreation Area. The trail winds through mature second-growth upland forest with views of the lake.

Protected by Indiana Department of Natural Resoucre

The mound, named for an early landowner, is a preserved feature in the Brookville Lake–Whitewater Memorial State Park Complex. The federal government purchased the area for flood control, wildlife, and recreation. Brookville Lake filled after construction of a dam in 1974, and IDNR now manages the area surrounding it.

The trailhead is next to a gravel parking lot near the end of Mounds Beach Road off State Route 101.


Big Bone Lick State Historic Site

Boone County, Kentucky

The birthplace of American paleontology The lick has several salt springs that attracted mastodons, mammoths, and other Ice Age mammals to the site. The discovery of the animals’ large skeletal remains at the location led to the naming of Big Bone Lick in the eighteenth century. A diorama recreates the ancient scene, and there are hiking trails and a museum. Paved, wheelchair-accessible trails lead to viewing points.

Protected by Kentucky State Parks

In a fund-raising effort during the 1950s, citizens of Boone and Kenton Counties, including thousands of school children, collected money to purchase the land and protect it. Ownership transferred to Kentucky State Parks in 1960, and state funds have been used to expand it several times.

The site is located three miles off the intersection of State Route 338 and US Route 42.

Dinsmore Woods Nature Preserve 

Boone County, Kentucky

This 107-acre natural area is adjacent to the historic Dinsmore Homestead (1842). The preserve has a 1.7-mile walking trail, old-growth forest, and a population of the endangered native species, running buffalo clover. The deeply-entrenched remnants of a pre-1800 buffalo trace, on which the animals traveled from the Licking River mouth to the Big Bone Lick salt springs, runs beside the trail at the preserve entrance and contains a length of the trail upslope.

Protected by Boone County Parks

In 1985, Mrs. Martha Breasted donated the land to The Nature Conservancy. In 2010, Boone County used proceeds from the Kentucky Heritage Land Conservation Fund to purchase the preserve from the Conservancy.

From I-75 (Florence-Burlington exit 181) go west on Route 18 for 10.5 miles. The preserve entrance is on the right, just past the Dinsmore Homestead. Park at Middle Creek Park parking lot, directly across the road from the entrance trailhead.

St. Anne Woods and Wetlands

Campbell County, Kentucky

Situated along the Ohio River in Melbourne, Kentucky, St. Anne Woods and Wetlands’ 164 acres of wetlands and mature forests are home to rare flora and fauna. The site’s lowland and upland forests hold a diversity of tree species, while wetlands contain water-filled depressions that provide a rich habitat for a variety of species. Previously the property of St. Anne Convent, the site has served as a beacon of research and education for over a century. Today faculty and students of Northern Kentucky University and Thomas Moore College conduct ecological studies on site.

Protected by Campbell County Conservation District

In 2013, the Campbell County Conservation District purchased the land with a grant from the Kentucky Heritage Land Conservation Fund. A conservation easement held by the Commonwealth of Kentucky protects the property in perpetuity.

A trail into the wetlands begins at a parking area beside Anderson Lane one quarter mile north of Kentucky Route 8 in Melbourne.

Battery Bates Woodlands

Kenton County, Kentucky

Battery Bates is an earthen Civil War cannon battery constructed by the Union Army and civilian volunteers. The three-sided fortification is the most intact remaining structure of the ten-mile line of defensive works built in 1862-63 to protect Cincinnati against Confederate attack. Rifle trenches and an associated military road are also in the mature upland forest around the battery. Recognizing the pivotal role these fortifications played, the National Register of Historic Places entered Battery Bates in 2018.

Protected by Covington Parks and Recreation

Battery Bates is named for Brigadier General Joshua Hall Bates, chairman of the Cincinnati Committee for Public Safety. It is located in the 246-acre “back-country” area of Devou Park, which is named for the family that donated the park to the City of Covington in 1910.

Licking River Greenway Trailhead

Kenton County, Kentucky

This narrow greenspace currently stretches for almost two miles along the west bank of the Licking River. A trail through riparian forest provides views of the Licking, a stream ecologists consider to provide a unique ecosystem in the region. Several relatively rare fish species are present as well as one of the world’s most diverse communities of freshwater mussels. Eleven of the river’s 50+ mussel species are globally endangered or threatened with extinction.

Protected by Covington Parks and Recreation 

In 2010, Covington became the first city to begin implementing this urban greenspace project. The completed greenway will span 12-14 miles and include land in three additional cities: Newport, Taylor Mill, and Wilder.

Hueston Woods State Nature Preserve

Butler County, Ohio

Beech and sugar maple trees comprise 80% of the trees in the preserve, an old-growth forest located within Hueston Woods State Park. The “Big Woods” are a remnant of the beech-maple forests that once covered much of Ohio. Miami University faculty and students have conducted numerous ecological studies in the 200-acre woodland. It was designated as a National Natural Landmark in 1967 and a State Nature Preserve in 1973.

Protected by Ohio Department of Natural Resources

Matthew Hueston settled the area in 1797 but preserved a remnant of the native forest. Morris Taylor, a conservationist, purchased the woods in the 1930s following the death of the last Hueston descendants. The state has owned and maintained the land since 1941.

The woodland is located on the state park’s Main Loop Road, between Acton Lake and the golf course.

Rentschler Forest Earthwork

Butler County, Ohio

This 2,000-year-old Adena or Hopewell earthwork originally consisted of a wall enclosing eleven acres on land overlooking the Great Miami River. Following years of erosion, only the entranceway to the earthwork survives: A 100-foot earthen ring embraced by two arcs. Private and public conservation of the earthwork has served to preserve the old-growth trees at the site.
