Navajo sedge is found in seep-springs on vertical cliffs of red-pink Navajo sandstone (Arizona Ecological Field Services Office 2002). At first glance, this perennial sedge looks a lot like a grass, with 25-40 cm long, grass-like leaves growing in bunches. However, this plant is a sedge, not a grass, for a number of reasons. Rather than being round like a grass, the stems of a sedge are three-sided, or triangular. Flowers are concentrated in 2 to 4 groups clustered at the end of a long thin stalk, 2-3 times the length of the leaves, with female flowers situated above male flowers. Flowering and fruit set occur from spring to summer, but most of the reproduction appears to be vegetative. (USFWS 1985)
Many of the plants grow at such great heights that the only way to reach them is by rappelling down cliff faces.
Seep-springs on vertical cliffs of pink-red Navajo sandstone.
Distribution & Occurrence
The species grows only where water seeps out of vertical Navajo sandstone cliffs, usually in shady areas, at 5700 to 6000 ft in elevation.
|Several populations are known from the Navajo Nation in Coconino, Apache, Navajo and San Juan Counties. At the time of listing (USFWS 1985), it was estimated that the three known populations contained fewer than 700 plants.|
