Measuring trees

Tree measurements are snapshots, not permanent facts. A redwood's height changes as leaders grow, break in storms, or suffer dieback. Girth measurements depend entirely on where and how the tape is placed—especially on sloping ground or around multi-stemmed trunks.

Because of this volatility, Among the Redwoods records measurements as evidence, not decoration. We do not automatically trust undocumented "tallest in the county" claims. Instead, we look for dated surveys, official arboretum records, or laser-measured field data.

When you see a height or girth on a place page, it should include a date and a source. Where a claim is approximate, old, or unsupported by recent visual evidence, the product says so plainly. Our goal is to provide a reliable baseline for visitors, not to mediate unverified champion contests.
