01Narrative

Archontophoenix maxima, the Walsh River palm, is the largest species of the genus Archontophoenix. It is endemic to Queensland, Australia. This robust palm grows in rainforest in altitudes of between 800 and 1200 metres on the Walsh River and the adjacent Mount Haig Range in the Atherton Tablelands at approximately 17° South latitude.

05DNA & barcoding1 specimens

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Archontophoenix maxima has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Archontophoenix maxima was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
