Methodology
Published does not mean trusted. Every place on the map is useful to discover; the confidence tier tells you how much to rely on it before travelling. Scraped listings start unverified. Visits, photos, and official sources raise confidence — never in one jump from scrape to field-checked. We would rather show you an honest 'not sure yet' than a confident guess.
Public confidence
On the map you will see one of three public tiers. The finer labels below explain what sits inside each tier and what it means for a visit.
Useful leads — noticed online, mapped from listings, aging, or disputed. Check before you travel.
Photos, named sources, or field clues support the record — still worth confirming access and species.
Confirmed on the ground by us, a partner, or a mapping walk.
Truth-seeking
A core part of our methodology is moving public candidates toward stronger records. We cross-reference claims against official estate publications, arboreta records, photos, repeated source clues, and trusted field observations when those signals exist.
Review
Official visitor information, reference material, field notes, and unresolved claims do different jobs. Among the Redwoods keeps those roles distinct so a visitor can tell what supports access, identity, or wider background.
A place can be real and still need care before a visit. Access notes, ticketing, opening, and route context are surfaced independently because trip planning depends on them.
Missing sources, stale access details, new photos, and field sightings all help sharpen the public record. Reviewed updates matter as much as the first listing.
Data
Among the Redwoods publishes place records for public reference with source attribution on each record. We do not yet publish the dataset under a formal open-data licence (such as ODbL or CC BY). Partner and contributor data stays attributed; ask before reusing bulk exports.
