Published register ↗

264 records are included in this imported selection. 258 have approximate map points; 6 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 264 distinct tree IDs returned by California Big Trees’ public listing endpoint, maintained by Cal Poly’s Urban Forest Ecosystems Institute and retrieved October 11, 2026. The data flags 263 state champions, 178 national champions, and 36 co-champions; these overlap. One Fremont cottonwood is marked only as co-champion, with no state or national flag, and retains that qualified label. No titles are derived from scores.

The homepage counter reports 247 listings and 181 national champions, which differs from the actual listing data. We use the records returned by the listing endpoint. No edition date is stated. Published champion designations and older measurement dates do not independently confirm current condition or national standing.

258 records use 46 approximate Census county points. Six have no county and remain searchable without markers. Two “Toulumne” labels are matched to Tuolumne County, with the original spelling retained and explained. Markers represent counties, not individual trees, and do not establish visiting permission. Individual coordinates, nominator and measurer names, contact IDs, and addresses are omitted, including for records with hidden locations.

The source’s accepted scientific names are used for species grouping; its alternate scientific labels remain in the notes. Common labels, decimal measurements, published scores, and measurement dates are preserved. Circumference is in inches; height and average crown width are in feet. January 1 dates may be legacy year-only entries and do not establish exact day precision.
