Cystopteris dickieana, commonly known as Dickie's bladder-fern, is a fern with a wide distribution in the Northern Hemisphere. There is debate amongst botanists as to whether it is a species in its own right or a variant of C. fragilis.

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 Cystopteris dickieana has left across the world's sequence archives.

09Environmental DNA5 detections
Where the DNA of Cystopteris dickieana 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.
