Description: Perennial plant often smooth to the touch, 8-14 dm tall. Leaf blades smooth, mostly 10-60 cm long, 4-8 mm wide; sheaths mostly smooth but often having long soft hairs marginally at collar; ligule 0.5-2.2 mm long. Panicles open to mostly narrow, 10-40 cm long; glumes sharply pointed, the first 4-6 mm long, the second 5-7 mm long; lemma sharply pointed, usually slightly shorter than second glume; palea firm, often equal in size to lemma. Anthers 2.9-4.5 mm long.

Origin: Native

Growing Season: A warm season grass beginning growth in early to mid May, flowering in late July, and setting seed through September.

Habitat: This species grows on prairies and plains, often dominating sandhill prairie regions. It is most commonly found on sand and sandy range sites, often associated with drier upland sites.

Distribution: Prairie sandreed occurs from Manitoba to Alberta south to Idaho, Kansas, Colorado, and Indiana. This species is found throughout the northern Great Plains region. It is commonly found throughout North Dakota on coarse textured soils. It is found in the south-western two-thirds of Minnesota.

Forage Value: This species provides fair to good forage value for cattle and horses and fair value for sheep during its first two months of growth and after it cures on the stem for fall and winter grazing. Crude protein content is about 16 percent in May, dropping to 4 percent by November. Although crude protein content is low in the fall and winter, available carbohydrates increase from 45 percent in May to 55 percent in November. This species is considered a decreaser with grazing pressure, but it will increase with initial heavy use, especially if growing within a big bluestem – sand bluestem plant community.

Wildlife Value: The foliage of this species will provide fair feed for grazing and browsing wildlife in the spring and early summer, becoming more important as a winter forage as it cures well on the plant, remains upright, accessible and nutritional. There is little information on the use of the seed by wildlife. The seeds are possibly used by some songbirds.

Description: An annual or short-lived perennial, 2-5.5 dm tall. Leaf blades are rolled, rarely folded, flat at maturity, 4-14 cm long, 2.8-6.5 mm wide; sheaths sometimes sparsely covered with soft hairs, normally smooth; ligules 0.6-1.3 mm long. Burs contain 30-60 spines; spikelets 2 or 3 per bur; largest spikelet with its first glume 0.8-3 mm long, its second glume 4-6 mm long, 5-nerved, the lemma of its first floret 4-6.1 mm long, palea of that floret usually as long as the lemma, enclosed in staminate flower. Anthers of the upper floret 0.7-1 mm long.

Origin: Native

Growing Season: A warm season grass beginning growth in early to mid May, flowering in July, and setting seed through September.

Habitat: Sandbur can be found growing on floodplains, in lawns, fields, and pastureland, becomes quite common on waste ground. This species is most commonly associated with sandy soils.

Distribution: This species can be found through-out most of the United States, becoming less common in northern states. Also common in Mexico and Central America. Sandbur may occur throughout North Dakota, especially on disturbed sandy soil. This plant occurs in the southern two-thirds of Minnesota.

Forage Value: This species is considered an undesirable plant that has limited forage value in the spring prior to seed set. Once burs are present it has no forage value. The burs are damaging to sheep fleece and goat hair, decreasing value of the product. This plant is considered an increaser with grazing pressure.

Wildlife Value: The value of this plant to wildlife is very limited, with only a few bird species utilizing the burs as feed.

Description: Tufted or matted perennial 1-7.5 dm tall. Culms are erect, smooth, and hollow. Leaf blades are smooth to covered with shallow depressions, thickened and whitish on the margins, midrib prominent and whitish below, folded in the bud and at maturity, tip boat-shaped, mostly 2-20 cm long, 1-4.5 mm wide when unfolded. Leaf sheaths smooth, keeled, open to the base; ligules membranaceous, whitish, usually torn, 3-7 mm long on the culm leaves; auricles lacking. Inflorescence a congested panicle 6-11 cm long, most branches bearing 1 or 2 large spikelets; spikelets 3- to 5-flowered, jointed above the glumes and between the florets, the rachilla bearded. Glumes about as long as spikelets, sharply tipped, thin and membranaceous, the first 3-nerved, 9-13 mm long, the second 3- to 5-nerved, 11-14 mm long; lemmas firm, 5-nerved, the lowest one 10-12 mm long, awned with a strong, bent, twisting awn 12-16 mm long. Anthers 2.7-4.5 mm long.

Origin: Native

Growing Season: A cool season grass starting growth in late April, flowering in June and July, and setting seed by August.

Habitat: This species grows in a variety of soil types where moisture is fairly plentiful, most commonly found on hillsides and open prairie slopes. It seldom forms dense stands, usually found as solitary plants scattered within a community.

Distribution: Spike oat can be found in south-central Canada, North Dakota, Montana, and Minnesota, most commonly found along the eastern slopes of the Rocky Mountains reaching all the way down to New Mexico. It can be found throughout North Dakota, but is often only found as a single plant within a community. This plant occurs only in the northwestern prairie region in Minnesota.

Forage Value: This species rarely exceeds 5 percent of the plant community, creating little overall forage value for livestock. It is rather palatable and a good forage prior to seed set, with crude protein content around 10 percent in mid July. This species is considered a decreaser with grazing pressure.

Wildlife Value: There is little information on the feed value of this species for wildlife, primarily due to its overall small composition within any one plant community. Since it seldom comprises more than 5 percent of the plant species mix, the overall value to the wildlife community would be small. No literature has been found that indicates an importance to any one wildlife species.

Leaf blades are soft, folded in the bud, usually flat at maturity, roughened, the midvein quite prominent beneath, mostly 10-43 cm long, 3-9 mm wide. Leaf sheaths are closed toward the base with margins overlapping and fused, smooth, keeled, and laterally compressed. Ligules are membranaceous, irregularly cut at maturity, 2.5-13 mm long; auricles none. Inflorescence a panicle with relatively few branches, the spikelets are clustered in 1-sided groups on short pedicels; spikelets compressed, 2- to 4-flowered, jointing above the glumes and between the florets. Glumes vary in texture and size, 2.5-7 mm long, approximately equal in size, 1- or 2-nerved, often markedly asymmetrical, sharply pointed or short-awned, smooth to rough or having minute hairs present, especially on the main nerve. Lemmas are rather faint, 5-nerved, gradually tapering to a point or short-awned, rough to slightly hairy, lowest lemma with an awn up to 1.3 mm long; paleas shorter than the lemma. Anthers 1.8-3.7 mm long.

Origin: Introduced from Europe and Asia, considered naturalized throughout North America.

Growing Season: A cool season grass beginning growth in late April and flowering from late May to early October.

Habitat: This species has been introduced primarily as a forage grass for pastures and hayland, however, when escaped it can occur on a variety of habitats associated with fine to coarse soils in crop fields, meadows, pastures, ditches, disturbed woodlands, and waste areas.

Distribution: This grass has been seeded and occurs throughout most of the United States, primarily in the upper two-thirds of the United States, in New Mexico, western Texas, and southern Canada. It is most abundant in the northwestern and northeastern regions of the United States. Orchard grass is rarely found growing naturally in North Dakota. However, when seeded, it is usually planted into previously cultivated lands in eastern North Dakota and mainly in the southern one-third of Minnesota.

Forage Value: This species provides good to excellent forage for all classes of livestock. It provides the best quality forage as pasture in the spring, declining rapidly with maturity. Orchardgrass cures well as hay, providing an excellent forage and is often seeded with legumes to provide a high quality and high producing feed. Orchardgrass stands need fertilizer to maintain high production. This grass is considered an invader on native rangeland.

Wildlife Value: This species is considered a highly desirable forage to grazing wildlife, especially in the spring. It is often relished by white-tailed deer. The seeds are used by some songbirds to an unknown extent but are not a necessity seed feed.
