DISTRIBUTION AND OCCURRENCE
SPECIES: Eleocharis rostellata | Beaked Spikerush 



GENERAL DISTRIBUTION : 
Beaked spikerush is widespread in the Americas from southern Canada
south through Mexico to the West Indies, the Caribbean, and the South
American Andes [4].  Although it is widespread in the conterminous
United States, beaked spikerush occurs in scattered disjunct populations
[12,13].  It may not be present in every state, especially in the
Appalachian Mountains and the Ozark Mountains.

HABITAT TYPES AND PLANT COMMUNITIES : 
Beaked spikerush occurs in saline or alkaline wetlands [13,21,23].  In
Montana thermal areas and alkaline seeps, beaked spikerush occurs with
common arrowgrass (Triglochin maritimum), hardstem bulrush (Scirpus
acutus), Torrey's rush (Juncus torreyi), and alkali muhly (Muhlenbergia
asperifolia).  Adjacent wetlands may be dominated by hardstem bulrush or
common arrowgrass [14].

In a saline meadow near Utah Lake, Utah, beaked spikerush occurs at low
densities in a common spikerush (Eleocharis palustris) community with
sea milkwort (Glaux maritima), saltgrass (Distichlis spicata), and
Baltic rush (Juncus balticus) [3].

In northern Minnesota, beaked spikerush occurs near spring-fen channel
margins with mud sedge (Carex limosa), lesser panicle sedge (C.
diandra), tufted bulrush (Scirpus cespitosus), whitebeaked rush
(Rhynchospora alba), and common reed (Phragmites australis).  These
channels have standing water and lack forest cover [10,11].

In a Delaware salt marsh, beaked spikerush is associated with saltgrass,
Olney threesquare (S. americanus), and saltmeadow cordgrass (Spartina
patens) [31].

Beaked spikerush is codominant in meadows in western New York with
needle beaksedge (Rhynochospora capillacea).  It forms small mounds or
tussocks within moss (Campylium stellatum) mats.  It also occurs with
low nutrush (Scleria verticillata) and Indian grass (Sorghastrum
nutans). [29].

At a calcareous seep in Illinois with sparse to patchy ground cover,
beaked spikerush and shrubby cinquefoil (Potentilla fruticosa) are
dominant.  Needle beaksedge and tufted hairgrass (Deschampsia cespitosa)
also occur [33].
