01Narrative

The Malagasy pond heron (Ardeola idae) is a species of heron of the family Ardeidae. They are primarily seen in the outer islands of the Seychelles, Madagascar, and on the east coast of Africa including Kenya, Tanzania, and Uganda. Being native to Madagascar, this species is often referred to as the Madagascar pond heron or Madagascar squacco heron. The population of this heron is estimated at 2,000–6,000 individuals, with only 1,300–4,000 being mature enough to mate.

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 Ardeola idae has left across the world's sequence archives.

09Environmental DNA1 detections

Where the DNA of Ardeola idae 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.
