The flowers are wind-pollinated and attract few insect visitors. The leaves are a preferred source of food for the caterpillars of Lycaena phlaeas americana (American Copper), which has been interpreted as an indication that this butterfly is an introduction from Europe. Upland gamebirds eat both the seeds and foliage, while many songbirds, especially sparrows, eat the seeds (see Bird Table). Various small mammals occasionally eat the seeds or foliage, including the Cottontail Rabbit, Prairie Vole, and White-Footed Mouse.

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].
