Can I use this data for free? +
Yes. All four datasets are free under CC BY 4.0. You can use them in articles, reports, slides, apps and research, including for business. Just credit Lirevon and link to this page.
How should I credit Lirevon? +
Use the citation on this page, or a short line such as "Source: Lirevon open data, https://lirevon.com/data". A link to the page you used, for example a state report, is also fine.
Where does the market data come from? +
From our own check of tree service and tree removal listings on Google Maps, finished October 26, 2026. We removed duplicates, franchises, closed listings and businesses that are not tree companies, then checked the home page of each website with our own script. The short method is on this page; the full method is on the report page.
Does the data name any tree companies? +
No. The market data is counts and shares only. No company, owner or phone number is in any file.
Why are some cells blank? +
A blank means we did not check that number for that area. For example, if we did not run website checks in a state, the texting and booking shares for that state are blank.
Is the licence data legal advice? +
No. It is a short summary of what we found on official sites, with a link to each source. Rules change, and cities and counties often have their own. Check with the state and your city before you rely on it.
How accurate are the species facts? +
They are typical, well established ranges of the kind a university extension service publishes. Local soil, climate and care change how a tree grows, so treat them as a starting point.
Can I see where a pest is found by state? +
Not in this file. Pest ranges change, so we point you to the official maps instead. As of 2026, check your state's official map from USDA APHIS, your state department of agriculture or your university extension.
Will you update the data? +
Yes, when we run a new check or review a page. The date columns tell you when each row was checked. Changes are noted on our changelog.
Can I put the numbers on my site as a live box? +
Yes. Our embed page has state data badges you can paste into your site. They update on their own if we run a new check.
I found a mistake. What should I do? +
Email hello@lirevon.com with the file, the row and what you think is right, ideally with a source. See our corrections page for how we check and fix errors.
