Carex vallicola is a species of sedge known by the common name valley sedge. It is native to western North America from British Columbia to New Mexico, where it grows in many types of moist and dry habitat, including forest and grassland. This sedge produces clumps of stems up to about 60 centimeters tall. The inflorescence is a crowded cluster of a few flower spikes. The fruit is enclosed in a brown perigynium.

Where the DNA of Carex vallicola 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.
