01Narrative

Melanodendron is a genus of trees in the family Asteraceae, with only one species, Melanodendron integrifolium (black cabbage tree), native to the island of Saint Helena (South Atlantic Ocean). It is related to the Saint Helenan gumwoods (Commidendrum spp.) and is the commonest of the remaining cabbage tree species of Saint Helena, although it is considered endangered due to the restricted population size.

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 Melanodendron integrifolium has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Melanodendron integrifolium 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
