Alopecurus saccatus is a species of grass known by the common name Pacific foxtail, or Pacific meadow foxtail. It is native the west coast of the United States from Washington to California, where it grows in moist areas at low elevations.

Where the DNA of Alopecurus saccatus 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.
