Occasional
More info for the terms: frequency, presence
Sheep sorrel is classified as a noxious weed in 23 states [67]. It is a
serious weed in pastures and rangelands. Control is difficult because
of its perennial, creeping rhizomes [4,52]. Sheep sorrel is a common
weed in West Virginia, except in limestone regions; liming the soil may
help eradicate sheep sorrel [82].
Sheep sorrel presence and abundance are indicative of poor and "sour"
soils [82,87]. It reaches peak abundance at low soil nitrogen levels
[87]. Sheep sorrel is potentially poisonous to livestock because of the
presence of soluble oxalates [19]; however, it is grazed by sheep and
cattle [39]. In Idaho sheep sorrel is an increaser species under heavy
grazing regimes, and a decreaser species under light grazing regimes
[54]. In Oregon percent frequency of sheep sorrel was not affected by
late season cattle grazing in a riparian mountain meadow [45].
In Novia Scotia sheep sorrel is one of the most common weed species in
lowbush blueberry fields. Control with hexazinone was attempted but
after the activity of the herbicide decreased, sheep sorrel grew and
produced a large number of seeds [62]. In Pennsylvania in a goldenrod
(Solidago spp.)-aster (Aster spp.) community, sheep sorrel was dominant
in 1- and 3-year-old plowed, disked, prometone-treated plots [64].
Control Methods: Repeat cultivation during dry weather gradually
weakens rootstalks of sheep sorrel [19]. According to Fitzsimmons [19]
several herbicides can selectively control sheep sorrel.
More info for the term: adventitious
Sheep sorrel is an introduced rhizomatous perennial herb that sometimes
forms dense colonies by adventitious shoots from widely spreading roots
and rhizomes [19,29,35,52,92]. Stems are erect, slender, and 4 to 24
inches (10-60 cm) tall [33,72,95]. Leaves are 0.8 to 4 inches (2-10 cm)
long and 0.4 to 0.8 inch (1-2 cm) wide [33,34,72]. The fruit is an
achene [25,29,38,72,95]. Roots are slender, almost fibrous and
penetrate to a depth of 5 feet (1.5 m) [48].
More info for the terms: cover, frequency, restoration
Some research describes no change in cover or frequency in sheep sorrel
after fire. In California the effects of a late fall burn on a mountain
meadow in Grover Hot Springs State Park were evaluated. Both wet and
dry meadow plots were prescribed burned by a low- to moderate-intensity
fire in mid-November 1987. Sheep sorrel was found only on dry plots
before burning and did not increase following fire [8].
In Connecticut experimental tracts were set up in a little bluestem
grassland in 1967. Tract A was prescribed burned annually from
1968-1976, and in 1978, 1980, 1983, and 1985. Tract B was prescribed
burned annually from 1968-1975, and in 1978, 1980, 1983, and 1985.
Sheep sorrel percent cover and frequency in two burns and 2 control
plots on each tract were as follows [69]:
Tract A Tract B
1967 1985 1967 1985
cover freq cover freq cover freq cover freq
treatment
Burn less than 1 9 2 6 less than 1 29 less than 1 5
Control less than 1 22 0 0 1 65 less than 1 27
The following Research Project Summaries provide information on prescribed
fire use and postfire response of plant community species, including sheep sorrel,
that was not available when this review was originally written:
- Vegetation response to restoration treatments in ponderosa pine-Douglas-fir
forests of western Montana - Effects of surface fires in a mixed red and eastern white pine stand in Michigan
- Vegetation change in grasslands and heathlands following multiple spring, summer,
and fall prescription fires in Massachusetts
Sheep Sorrel is usually found in full or partial sunlight, mesic to dry conditions, and a poor acid soil that is either sandy or gravelly (although not limestone). It can also flourish in rich loam or clay-loam soil at highly disturbed sites. This plant is quite aggressive and difficult to eradicate. Range & Habitat

Plants perennial, glabrous, with vertical rootstock and/or creeping rhizomes. Stems erect or ascend-ing, several from base, branched in distal 1/ 2 (in inflorescence), 10-40(-45) cm; shoots variable. Leaves: ocrea brownish at base, silvery and lacerated in distal 1/ 2; blade normally obovate-oblong, ovate-lanceolate, lanceolate-elliptic, or lanceolate, occasionally, linear-lanceolate to almost linear, 2-6 × 0.3-2 cm, base hastate (with spreading, entire or sometimes multifid, dissected lobes), occasionally without evident lobes, then base broadly cuneate, margins entire, flat or nearly so, apex acute or obtuse. Inflorescences terminal, usually occupying distal 2- 3 of stem, usually lax and interrupted to top, broadly or narrowly paniculate. Pedicels 1-3 mm. Flowers (3-)5-8(-10) in whorls; inner tepals not or slightly enlarged, normally 1.2-1.7(-2) × 0.5-1.3 mm (free wing absent or barely visible), base cuneate, apex obtuse or subacute. Achenes brown or dark brown, 0.9-1.5 × 0.6-0.9 mm. 2n = 14, 28, 42.
