Present on Pacific Islands?  yes

Primarily a threat at high elevations?  no

Other Latin names:  Festuca bromoides L.

Common name(s): [more details]

English: barren fescue, brome fescue, desert fescue, squirreltail fescue

French: vulpie faux brome

Spanish: pasto de sedilla

Habit:  grass

Description:  "Glabrous annuals; culms loosely tufted, base decumbent, 1-3 (-5.5) dm tall, lower nodes geniculate.  Sheaths open, sparsely to evenly pilose or glabrous, margins membranous, overlapping; ligule erose-ciliate, 0.2-0.6 mm long; blades usually involute, filiform, lower surface pubescent.  Panicles often slightly secund, narrow, 2-8 (-12) cm long, with short, ascending branches, sometimes the lower branches spreading; spikelets 3-5 (-6)-flowered; glumes unequal, first glume 3.5-5 (-7) mm long, filiform, 1-nerved, second glume lanceolate, 4.5-8 mm long, prominently 3-nerved, sometimes slightly awn-tipped; lemmas (4-) 5.5-7.5 mm long, minutely scaberulous or glabrous, the awns (4-) 6-11 (-15) mm long; palea narrow, apex bifid.  Caryopsis 3.5-4 mm long"  (Wagner et al., 1999; p. 1603).

Description from GrassBase.

Habitat/ecology:  "Grass- and heathland, riparian habitats, freshwater wetlands, coastal beaches.  This shallow-rooted grass grows well in soils of low fertility.  Where invasive, it successfully competes with native grasses and forbs for water, space and nutrients.  It forms dense swards crowding out native plants and reducing species richness"  (Weber, 2003; p. 452).

In Hawai‘i, "naturalized in dry, disturbed sties such as along roadsides, in pastures, and on rocky slopes, 185-2,590 m" (Wagner et al., 1999; p. 1603).

Propagation:  Seed

Native range:  "Native to Europe, northern Africa and Asia Minor" (Wagner et al., 1999; p. 1603).

Control: 

Physical:  "Scattered plants can be hand pulled or dug out.  A combination of grazing in spring (to reduce seed set) and grazing in autumn (to reduce seedling establishment) has shown to reduce the density of the grass".

Chemical:  "Chemical control includes spraying flowering plants with glyphosate to prevent seed set, or treating with simazine, simazine plus paraquat, or dalapon"  (Weber, 2003; p. 452).
