What Is a Champion Tree?
When we talk about champion trees, we’re referring to the largest known individuals of a tree species within a defined area, such as a county or state. In Ohio, champion trees are recognized based on three scientific measurements:
- Trunk Circumference at 4.5 feet above ground
- Total Height from base to highest living tip
- Average Crown Spread — the width of the canopy
These measurements are combined into a score using this formula:
Total Champion Points = Circumference (inches) + Height (feet) + (¼ × Crown Spread in feet)
The highest-scoring tree of each species earns official recognition. This method ensures champions are identified based on quantifiable size, not subjective impressions.
Champion trees can be categorized as:
- State champions – recognized as the largest of a species in Ohio
- National champions – largest in the United States
- Local champions – notable within a county or community
The Ohio Champion Tree Program Explained
In Ohio, the Ohio Champion Tree Program is overseen by the Ohio Department of Natural Resources, specifically through its Division of Forestry. The program:
- Maintains an official registry of Ohio’s largest trees
- Provides measurement standards and documentation
- Encourages conservation awareness
- Supports citizen participation in identifying new candidates
Champion trees are tracked not just for size but as living records of ecological resilience and natural history.
As of 2026, Ohio’s statewide registry includes many species, from sycamores and oak to silver maple and tulip poplar — each chosen based on size, not age or rarity.
Why Delaware County and Lewis Center Produce Giant Trees
Lewis Center, located in Delaware County, Ohio, benefits from a unique combination of natural factors that support large tree growth:
Glacial Soil Richness
The soils beneath Lewis Center are remnants of ancient glacial activity—deep, nutrient-rich, and well-drained. These conditions support long, sustained growth for hardwoods like oak and maple.
Access to Water
Nearby waterways such as the Olentangy River and Alum Creek maintain moist soils ideal for species like cottonwood and sycamore, which require abundant water to reach large size.
Historical Land Use
Much of the landscape around Lewis Center was once farmland or pasture. In many cases, farmers preserved shade trees, allowing them to grow without competition. Over time, suburban growth expanded around these trees, rather than replacing them in some locations.
This combination of soil, water, and a history of relatively low disturbance has allowed trees to grow larger than in many other suburban regions.
Notable Champion & Near-Champion Trees in Lewis Center
While some champion trees in the Lewis Center area may not always appear on official state lists — often due to private land ownership or lack of formal nomination — several remarkable specimens are locally known and occasionally documented:
Historic White Oak
One of the most talked-about giants in the Lewis Center area is a massive white oak, often cited for its size:
- Trunk Circumference: ~233 inches
- Height: ~65–71 feet
- Crown Spread: ~124 feet
This specimen, though sometimes not officially listed, is frequently referenced by local tree enthusiasts as one of the region’s largest hardwoods.
Eastern Cottonwood
Trees of the species Populus deltoides — Eastern cottonwood — thrive near Alum Creek and other drainage corridors. The largest cottonwoods in Delaware County can exceed:
- Height: over 120 feet
- Circumference: nearly 380 inches
This makes Delaware County home to some of Ohio’s most impressive cottonwoods.
American Sycamore
Sycamores (Platanus occidentalis) are among Ohio’s most massive trees, often dominating floodplain forests. While Ohio’s top sycamore champions are outside Lewis Center, similar trees in local parks, especially within Highbanks Metro Park, approach champion-caliber size.
Other Large Species
Other species with strong champion potential in the region include:
- Silver Maple (Acer saccharinum)
- Bur Oak (Quercus macrocarpa)
- Tulip Poplar (Liriodendron tulipifera)
- Ohio Buckeye (Aesculus glabra)
These trees thrive in moist soils and have broad crowns that contribute heavily to champion scores.
Public Places to See Large Trees Near Lewis Center
Even if specific champions are on private property, several public spaces near Lewis Center allow visitors to experience impressive trees:
Alum Creek State Park
This state park protects large cottonwoods, sycamores, and other hardwoods along the creek — many of which have reached remarkable size due to consistent moisture and long-term preservation.
Highbanks Metro Park
Highbanks is especially known for its mature forests and deep ravines. Though not all trees there are officially registered, many old oaks and maples grow to impressive dimensions and are often champion candidates.
Other Natural Areas
Local parks, protected greenspaces, and older sections of neighborhoods often contain large trees visible from public trails or right-of-way areas.
How Champion Trees Are Measured: Step-by-Step
Anyone interested in champion trees can measure and potentially nominate a tree. Here’s how:
1. Circumference
Measure the trunk circumference at 4.5 feet above the ground — this is known as Diameter at Breast Height (DBH).
2. Height
Height is measured from the tree’s base to its highest living branch. Professionals use tools like a clinometer or laser rangefinder for accuracy.
3. Crown Spread
Measure the widest part of the canopy and the narrowest part, average them, and use this figure in the scoring formula.
Once these are recorded, submit measurements and photos to the Ohio Division of Forestry for verification.
The USD Value of Lewis Center Champion Trees
Champion trees are more than natural wonders — they have measurable economic value in United States Dollars (USD), providing long-term services that benefit communities:
Property Value Boost
Large, mature trees can increase residential property values by up to 15% compared to similar properties without significant tree cover.
Stormwater Management Savings
Champion trees intercept thousands of gallons of stormwater annually through their expansive canopies, reducing infrastructure costs.
Energy Savings
Shade from large trees can reduce cooling costs in summer and heating costs in winter, saving homeowners tens or even hundreds of dollars per year.
Carbon Sequestration
Big trees store carbon dioxide — potentially hundreds of pounds per year — contributing to climate mitigation. As carbon credit markets grow, this storage has real economic value.
Combining environmental and financial benefits, a single champion tree can provide hundreds to thousands of USD worth of services annually, depending on species and size.
Environmental Benefits of Large Trees
Beyond economics, champion trees play vital ecological roles:
- Air purification: Removing pollutants and greenhouse gases
- Wildlife habitat: Supporting birds, insects, and mammals
- Soil stabilization: Preventing erosion
- Flood mitigation: Slowing stormwater runoff
- Shade & microclimate cooling: Reducing urban heat islands
These benefits multiply as trees grow older and larger.
Historical Significance of Delaware County Trees
Trees around Lewis Center are natural history markers, often pre-dating modern development:
- Some trees began growing when the area was farmland
- Many survived agricultural clearing due to cultural respect or utility
- These living witnesses connect current residents to the region’s natural past
Local stories about legendary trees — such as the large white oak that shaped neighborhood design — showcase how nature and human history intertwine.
Threats Facing Champion Trees in Lewis Center
Despite their size, champion trees face risks:
- Urban development and root damage from construction
