Lewis Center Ohio champion trees are the biggest verified trees of each species around this Delaware County community, ranked by points. A champion wins not on looks or age, but because its trunk, height and crown outscore every other known tree of its species in Ohio.
One honest point first. Ohio keeps records at state level through the Big Tree program of the Ohio Department of Natural Resources Division of Forestry, with no separate register for Lewis Center alone. A local champion is a top scoring area tree checked against the state list. The best documented giant nearby stood in Alum Creek State Park, and Highbanks Metro Park in Lewis Center holds old growth that shows why big trees survive here.

What Are Champion Trees in Ohio?
A champion tree in Ohio is the largest living example of its species in the state, held on the state Big Tree list. Ohio has tracked its biggest trees since the 1950s, following the American Forests model from 1940, across more than 200 species.
Definition of a Champion Tree
A champion is the biggest scored specimen of one species in a set boundary, state or national. It must be correctly identified, measured in the standard way, and scored above the current record holder. The title is never permanent.
How Champion Trees Are Measured
Every contender is measured the same three ways:
- Trunk circumference, taped at 4.5 feet above the ground, called breast height
- Total height, from ground level to the highest live point of the crown
- Average crown spread, from the widest and narrowest crown widths averaged together
If a trunk forks or swells at breast height, measurers use the narrowest normal point below it. On a slope, they measure from the uphill side.
State vs National Champion Tree Designations
A state champion is the biggest of its species in Ohio, and a national champion is the biggest in the United States. The national register uses the same points formula, one tree can hold both titles, Ohio has held national titles for oaks and black cherry, and close scores can produce co champions.
Why Lewis Center, Ohio Is Known for Champion Trees
Lewis Center sits in southern Delaware County, between the Olentangy River and Alum Creek. Big trees survive here because farming left woodlots standing and river corridors kept forest intact. The proof is Highbanks Metro Park, over 1,200 acres in Lewis Center and a National Natural Landmark since 1980, with trees of about 150 years old and two sycamores reported at 23 to 24 feet around.
Natural Environment and Soil Conditions
Glacial soils here are deep and moisture holding, which suits long lived hardwoods. Valley bottoms stay moist in dry spells, uplands drain well, and ravines cut by glacial meltwater shelter trees from strong winds.
Historical Land Use and Tree Preservation
County surveys from 1832 and 1835 show the original forest: beech at about 35.7 percent by basal area, then white oak at 16.0 percent, sugar maple at 15.7 percent and red oak at 14.0 percent. Farmers left woodlots, fence lines and stream banks standing, where many old trees still stand.
Suburban Growth and Surviving Mature Trees
Lewis Center has grown fast, yet growth did not clear everything. Land for Highbanks was bought from 1948, before the housing boom, and the park opened in 1973. Some builders kept mature yard trees, and floodplains stayed unbuilt.
Types of Champion Trees Found in Lewis Center
Champion size here comes from the hardwoods of the original county forest, plus fast growing river trees. Each species is only compared with its own kind. Our overview of Ohio champion trees in the Lewis Center area covers the same ground from a statewide angle.
Common Native Tree Species
Regular contenders are sycamore, sugar maple, silver maple, shagbark hickory, beech, tulip tree and eastern cottonwood. Sycamore and cottonwood grow huge near water.
Large Hardwood and Oak Varieties
Oaks carry many titles because they live long and keep growing for centuries. Local candidates include white oak, northern red oak, bur oak and chinquapin oak. Preservation Parks notes the largest American sycamore on the state list measured 432 inches around and 124 feet tall, while the biggest Ohio buckeye in the state measured 144 inches around and 77 feet tall.
Rare or Unusual Tree Specimens
Some titles go to trees that are small overall but huge for their kind. Redbud and dogwood champions may stand only about 30 feet tall. Ohio buckeye, the state tree, is closely watched, since the largest known example in the country has stood in Kentucky.
How Champion Tree Status Is Determined
A tree must be nominated, measured by the book and verified before the list changes.
Measurement Criteria Used in Ohio
Ohio uses the national standard: circumference in inches at 4.5 feet, height in feet, often taken with a laser or clinometer, and average crown spread in feet. Species identity must be confirmed too.
Scoring System for Champion Trees
The formula gives one point per inch of trunk, one point per foot of height, and a quarter point per foot of average crown spread.
| Part measured | Unit | Points earned |
|---|---|---|
| Trunk circumference | Inches | 1 point per inch |
| Total height | Feet | 1 point per foot |
| Average crown spread | Feet | 0.25 points per foot |
So a tall, slim tulip tree can lose to a shorter, thicker oak, because girth earns points fastest.
Verification and Re-Measurement Process
A forester or trained measurer visits to check species and health and retake all three measurements. Champions are remeasured over time, and a tree that dies, falls or is beaten drops from the top spot.
Who Identifies and Maintains Champion Trees
State staff, local experts and residents each play a part, and most new champions start with a resident who noticed a very big tree.
Role of Ohio Department of Natural Resources
The Division of Forestry inside the Ohio Department of Natural Resources runs the Ohio Big Tree program, publishes the rules and nomination form, and verifies contenders. Read the rules on the Ohio Big Tree program page.
Local Arborists and Forestry Experts
Certified arborists confirm tricky species such as oaks and hickories, take height and crown readings, and judge tree health. Volunteer big tree hunters also measure trees and pass strong results to the state program.
Community and Volunteer Contributions
Most nominations come from the public. Walkers and landowners report oversized trees, and owners give the permission without which a private tree cannot be verified. Big trees are most often found in yards, cemeteries and parks, where open space lets a wide crown develop.
Why Champion Trees Matter to Lewis Center
A champion grade tree is a living record of this land before the suburbs, and it does heavy practical work every day.
Environmental and Ecological Value
One huge tree stores far more carbon and catches far more stormwater than a young replacement. Deep roots hold creek banks together, and old trees host fungi and insects young trees cannot yet support.
Historical and Cultural Importance
The oldest local trees were standing when the surrounding farms were young. Boundary trees once marked farm lines, and inside Highbanks, earthworks built by the Cole Culture between about 800 and 1300 stand in the same woods as the oldest oaks.
Educational and Community Impact
School groups use park giants to teach measuring and species identification, and Highbanks uses the old growth preserve as an outdoor classroom. See also our piece on Lewis Center champion trees in detail.
Benefits of Champion Trees for the Local Community
Shade, cleaner air and wildlife habitat all trace back to keeping the biggest trees alive.
Wildlife Habitat and Biodiversity
Hollows shelter owls, bats and woodpeckers, acorns and hickory nuts feed deer and squirrels, and oak leaves feed caterpillars that feed nestling birds. Highbanks is home to nesting bald eagles.
Climate and Air Quality Benefits
A mature canopy cools the ground below and cleans the air passing through it. Shade lowers summer temperatures near homes, leaves trap dust and traffic pollutants along roads such as Columbus Pike, and evaporation moistens hot, dry air.
Property and Aesthetic Value
Streets with mature trees are the streets people most want to live on. A landmark tree gives a neighbourhood identity, and shade cuts cooling costs.
Where to Find Champion Trees Near Lewis Center
Start with public land: Highbanks Metro Park inside Lewis Center, and Alum Creek State Park nearby, where the famous county cottonwood stood. Spots for private champions are often kept quiet.
Public Parks and Green Spaces
Public parks give legal, safe access. Highbanks covers over 1,200 acres, with 100 foot shale bluffs above the Olentangy River, and Alum Creek State Park offers shoreline and ravine forest around the reservoir.
Nature Preserves and Walking Trails
The Edward F. Hutchins Nature Preserve, a 206 acre parcel in southern Highbanks, protects the best old growth, mostly oak, maple and hickory.
Publicly Accessible vs Private Locations
Many record trees stand in private yards, farms and cemeteries. Never enter private land to measure or photograph a tree without permission, and contact the owner first if you think one could be a champion.
Protection and Conservation of Champion Trees
A listing brings attention, not a legal shield. Real protection comes from park ownership, local rules and careful owners together.
Local and State Protection Guidelines
Protection depends on where the tree stands. Park trees are managed under plans that favour keeping them, county review can limit damage during development, and on private land the owner decides.
Tree Health Monitoring and Care
Old trees decline slowly, so regular checks catch problems while they are fixable. Inspections look for dead limbs, fungus, cracks and root damage, and mulch and drought watering extend life.
Threats from Development and Disease
The biggest risks are ground disturbance and disease. Digging and paving in the root zone wound roots, oak wilt moves between nearby oaks, and storms can cut a champion score in one night.
Best Practices for Preserving Champion Trees
Keeping a giant alive is mostly about leaving its roots alone.
Responsible Land Management
Fence off a root protection zone at least as wide as the crown during building work, keep heavy vehicles and soil piles out of it, and avoid changing ground level near the trunk.
Tree Care and Maintenance Standards
Use a certified arborist for pruning and remove dead wood only. Never top a large tree, since topping triggers weak regrowth and decay, and keep mulch away from the bark.
Community Awareness and Education
Trail talks help visitors value a tree without climbing or carving it, and reporting damage early gives arborists time to act.
Common Risks and Challenges Facing Champion Trees
Champions are old, tall and exposed, and their size catches wind, lightning and climate stress.
Urban Expansion and Construction Damage
Delaware County is one of the fastest growing parts of Ohio. Roots are cut for foundations and utility lines, and damage often shows up as crown dieback years later.
Severe Weather and Climate Stress
The Alum Creek cottonwood is the local warning. Recorded as Ohio champion eastern cottonwood at 358 inches in circumference, 136 feet tall and 135 feet in crown spread, for 528 points, it took serious storm damage in 2020 and its champion days ended.
Pests, Invasive Species, and Disease
Emerald ash borer has killed ash trees across Ohio and wiped out past contenders. Fungal root rots weaken the base long before the crown shows trouble.
How Trees Become Officially Recognized as Champions
Recognition follows a clear path: find, measure, document, verify, list. Anyone can start it.
Nomination and Application Process
Identify the species, take the three measurements, compare the score with the current state champion, and submit the nomination to the Ohio Division of Forestry if your tree looks close or ahead. American Forests sets out the national steps in its guide on how to nominate a champion tree.
Documentation and Measurement Requirements
You need photos of the whole tree, the trunk being measured and the crown, plus measurements with notes on slope or forks. National nominations ask for six photos, including one with a person for scale.
Review and Approval Timeline
There is no fixed deadline. A forester reviews the paperwork, visits genuine contenders, and updates the list after verification.
Champion Trees in Lewis Center vs Other Ohio Regions
Lewis Center does well for a suburb because its giants grow in protected parkland, not farm corners alone.
Comparison With Central Ohio Areas
Columbus city parks hold fine trees, but heavy use limits crown spread, while rural Delaware and Knox counties hold huge open grown oaks in fields and cemeteries. Lewis Center sits between the two. Preservation Parks of Delaware County promotes the state list in its article Ohio Big Trees.
Urban vs Rural Champion Tree Distribution
Most champions stand where a tree got open space and a long, undisturbed life. Yards and cemeteries produce the widest crowns, dense forest the tallest trunks, and floodplains the fastest growth and largest trunks.
What Makes Lewis Center Unique
Few suburbs offer a National Natural Landmark forest inside their boundary. Preserved green space at Highbanks protects old growth instead of isolated trees, and two water corridors meet in one small area.
Documented Big Trees Near Lewis Center: What the Records Actually Show
First, the Alum Creek eastern cottonwood in Delaware County, by Cheshire Road at Africa Road. Its 528 points came from a 358 inch circumference, 136 feet height and 135 feet crown spread. Reports after 2020 describe heavy storm damage and the loss of its champion status.
Second, the Highbanks sycamores in Lewis Center, recorded at 23 to 24 feet in circumference. They are not claimed here as official state champions, since that title needs a verified state listing.
FAQs
What qualifies a tree as a champion tree in Ohio?
It must hold the highest verified score for its species in Ohio: circumference in inches, plus height in feet, plus one quarter of average crown spread in feet.
Are champion trees only found on public land?
No. Champions stand on public and private land, and yards and cemeteries produce many winners. Private trees need owner permission.
Who is responsible for measuring and verifying champion trees?
The Ohio Division of Forestry holds the list, and foresters, arborists and trained volunteers check the measurements.
Are Lewis Center Ohio champion trees protected from removal or development?
Not automatically. A listing brings recognition, not a legal ban. Park trees are protected by park management, private trees by local rules and the owner.
Can a champion tree lose its status over time?
Yes, if a bigger tree is verified, if storm or disease cuts its score, or if it dies, as the Alum Creek cottonwood did after 2020.
How can I nominate a big tree in Delaware County?
Measure the trunk at 4.5 feet, the height and the crown widths, work out the points, get landowner permission, and submit the nomination to the Ohio Division of Forestry with photos.
Where is the best place to see a giant tree near Lewis Center?
Highbanks Metro Park is the best start, since its Hutchins Nature Preserve holds old growth plus two very large sycamores on public trails. The Alum Creek cottonwood site by Cheshire Road is the most famous single tree spot in the county.
