How-To
How to Report an Invasive Plant Sighting
You do not need a degree in botany to help track invasive plants across Central Ohio. When you spot something growing where it should not (honeysuckle creeping up a streetside tree, garlic mustard carpeting a park understory, or knotweed taking over a roadside ditch), a simple report from the field gives volunteers and researchers the real-time data they need to map invasions, plan removal work, and protect our native species.
Step 1: Take Clear Photographs
The foundation of any good report is a photo, or several. You do not need professional equipment. A smartphone camera works perfectly. Capture the whole plant if you can, so someone can see its overall shape and size. Then zoom in and photograph a close-up of the leaves. If the plant is flowering or has fruit, get a clear shot of that too, because flowers and seed pods are often how invasive plants are identified.
It helps to include something for scale, like your hand, a coin, or a nearby object you recognize. Make sure the photo is in focus and well-lit. If you are photographing in heavy shade, move closer to a clearer area or come back when the light is better.
Step 2: Document the Location
Where you found it matters as much as what you found. Write down or use your phone's map app to capture the exact location. Include the county and the nearest landmark (a street name, park entrance, trail marker, or intersection). GPS coordinates are even better if your phone has location turned on. Many community science apps collect location automatically.
Precision helps. "Honeysuckle near the Olentangy" is a start, but "honeysuckle at the corner of High Street and Park Drive in Columbus" is far more useful. If you are in or near a metro park, include the park name and the specific trail or area.
Step 3: Record the Date and Size
Note the date you made your observation. This matters for tracking seasonal growth and timing removal efforts. Also estimate the infestation size. Is this a single plant, a patch covering a few feet, or a widespread infestation covering acres? Use simple language like "isolated plant," "small patch," or "large dense area." Your honest estimate is the data researchers need.
Step 4: Choose a Reporting Channel
You have several good options for getting your report into the hands of people who can act on it.
Community Science Apps
Several free apps designed for plant observation and species tracking work well in Ohio. These platforms let you upload your photos, location, and description, and your observation joins a larger regional or national database. Data from these apps often flows to universities, conservation groups, and state agencies tracking invasive spread.
Local Parks and Metro Parks
Metro parks and local parks departments have stewardship staff who actively manage invasives. You can contact your local park directly (look up the parks office for your county) and describe what you found and where. Parks that know about infestations can prioritize removal work and plan restoration planting. This is especially useful for invasives found on public land.
Soil and Water Conservation Districts
Every county in Ohio has a soil and water conservation district that works on watershed protection and invasive species management. Contact your county's district and share what you have observed. They track invasive trends across the landscape and can connect you with removal efforts or volunteer opportunities.
This Site's Contact Form
You can also report directly to us using our contact form. Share your photos, location details, and observations. Confirmed reports help build the picture behind our species guides. We will do our best to verify your observation and note it as a documented sighting across the Upper Scioto watershed.
Why Your Report Matters
Invasive plants spread fast, especially in disturbed soil along roadsides, near water, and in forest edges. Once an invasive gains a foothold, it becomes much harder to control. Early detection stops invasions before they explode. A single report of garlic mustard in a new park can trigger removal efforts before it sprawls into thousands of plants.
Your observations also build a map. Over time, patterns emerge: which roads have the most honeysuckle, which parks need immediate restoration, which invasive species are moving upstream into new counties. This big-picture view is impossible without people on the ground reporting what they see.
Frequently Asked Questions
Why does my report matter?
Early reports help map how invasive species spread and guide removal efforts. Your observation from the field contributes to a larger picture of invasions across the Upper Scioto watershed. A single report can prompt action before a small infestation becomes unmanageable.
Do I need to be an expert to report?
No. Clear photos and an honest description of what you saw is enough. You do not need to identify the species with certainty. Photos of leaves, flowers, or the whole plant help others confirm what you found. If you are unsure, say so in your report.
What happens after I submit a report?
Reports are reviewed by volunteers and, when confirmed, added to our records. Depending on which channel you use, your data may also feed into larger community science databases that help researchers track invasive spread across Ohio. You may or may not hear back about your specific report, but it becomes part of the bigger picture we are all building together.
Before You Go
Reporting takes only a few minutes but can make a real difference. Keep your phone handy when you are out walking your neighborhood, your favorite park, or along the Olentangy and Scioto. When you spot something that looks invasive, stop, take a photo, note the location, and submit it through whichever channel feels easiest. Not sure what you are looking at?
