Published registerCounty registerAlphabetical register

846 records are included in this imported selection. 846 have approximate map points; 0 remain searchable without a marker. Multiple trees can share one town or county point.

Register editions, retrieval dates, and individual measurement dates describe different things. This snapshot does not confirm current tree condition. Approximate map points do not locate individual trees or establish permission to visit.

How this register was selected and mapped

All 846 records from the Colorado Tree Coalition’s 2026 county and alphabetical workbooks are included. Both lists reconcile across names, measurements, scores, positions, and general locations, with one cultivar-name difference: Hot Wings in the county list and GarAnn Hot Wings in the alphabetical list. The difference is noted on its record.

The register includes 354 position-1 or 1T listings, other positions through 7, and one entry without a position, height, or points. We preserve every published position and T suffix rather than calculating titles or reducing the list to three trees per species. The “Nat’l Pts.” column gives points; it does not establish national champion status.

All records map to 45 approximate Census county points. The source’s Moffatt spelling maps to Moffat County. One street address is omitted, and no individual-tree coordinates or visiting permission are inferred. Dates of measurement are not supplied. Circumference and diameter are in inches; height and average crown spread are in feet. Source spellings, varieties, missing values, and published scores remain intact.

From a record to a relationship

Get to know the trees.

These Library species appear in Colorado’s imported register. Explore identification, seasonal observations, and a practice beside a tree. Photographs are species references taken elsewhere. Matches use scientific names without regard to capitalization; botanical synonyms remain separate.

A place to begin outdoors

Plan a thoughtful visit.

Our available Colorado guides pair arrival and access information with a practice. A guide may feature an ordinary tree, a forest, or a champion; its inclusion here does not give it a champion title. Check current site guidance before travelling.

Cottonwood at Chatfield Farms

Choose a permitted path-side viewpoint of the cottonwood, leaving the bridge and paths clear. Follow a moving leaf or branch tip, then widen your view to the surrounding garden. A short garden visit is enough.
