Juncus nevadensis is a species of rush known by the common name Sierra rush. It is native to much of western North America from British Columbia to New Mexico, where it grows in wet areas in many habitat types. This is a rhizomatous perennial herb which varies in appearance. Its thin, smooth stems reach a maximum height between 10 and 70 centimeters. The thin green leaves may be up to 30 centimeters long. The inflorescences generally contain a number of flowers, with each flower bearing dark to very light brown tepals, six stamens with large anthers, and very long stigmas. The fruit is a shiny chestnut brown capsule.

Where the DNA of Juncus nevadensis 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.
