Tallgrass Prairie
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba. They were characteristically found in the central forest-grasslands transition, the central tall grasslands, the upper Midwest forest-savanna transition, and the northern tall grasslands ecoregions. They flouris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bouteloua Gracilis
''Bouteloua gracilis'', the blue grama, is a long-lived, warm-season (C4 carbon fixation, C4) Perennial plant, perennial grass, native to North America. It is most commonly found from Alberta, Canada, east to Manitoba and south across the Rocky Mountains, Great Plains, and U.S. Midwest states, onto the northern Mexican Plateau in Mexico. Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains. It is a green or greyish, low-growing, drought-tolerant grass with limited maintenance. Description Blue grama has green to greyish leaves less than wide and long. The overall height of the plant is at maturity. The flowering stems (culm (botany), culms) are long. At the top are one to four, usually two, comb-like spike (botany), spikes, which extend out at a sharp angle from the flowering stem. Each spike has 20 to 90 spikelets. Each spikelet is long, and has one fertile floret and one or two reduced steril ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortgrass Prairie
The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama (''Bouteloua gracilis'') and buffalograss (''Bouteloua dactyloides''), the two less dominant grasses in the prairie are greasegrass (''Tridens flavus'') and sideoats grama (''Bouteloua curtipendula''). The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less Precipitation (meteorology), precipitation than that of the tall and mixed grass prairies to the east. The prairie includes lands to the west as far as the eastern foothills of the Rocky Mountains and extends east as far as Nebraska and north into Saskatchewan. The prairie stretches through parts of Alberta, Wyoming, Montana, North Dakota, South Dakota, and Kansas, and passes south through the High Plains (United States), high plains of Colorado, Okl ...

Sporobolus Cryptandrus
''Sporobolus cryptandrus'' is a species of grass known as sand dropseed. It is native to North America, where it is widespread in southern Canada, most of the United States, and northern Mexico. Description ''Sporobolus cryptandrus'' is a perennial bunchgrass forming a tuft of stems growing up to a meter long, erect to decumbent in form. The stem bases are thick but not hard or woody. The leaves are up to long and rough-haired along the margins. Some stand out from the stems in a perpendicular fashion. The inflorescence is dense and narrow when new, spreading out and becoming diffuse, with some branches sticking straight out, with age. The base of the inflorescence is often sheathed within the top leaf, which spreads out beside it. The grass produces abundant seeds; an individual inflorescence is capable of bearing 10,000 seeds. Habitat Sand dropseed is a common grass in many types of North American prairies and grows in a wide variety of other habitats, including disturbed are ...

Bouteloua Curtipendula
''Bouteloua curtipendula'', commonly known as sideoats grama, is a perennial, short prairie grass that is native throughout the temperate and tropical Western Hemisphere, from Canada south to Argentina. The species epithet comes from Latin "shortened" and "hanging". Description Sideoats grama is a warm-season grass. The culms (flowering stems) are tall, and have alternate leaves that are concentrated at the bottom of the culm. The leaves are light green to blue-green in color, and up to across. The flowers bloom in summer and autumn. They consist of compact spikes that hang alternately in a raceme along the top of the culm. The spikes often fall to one side of the stem, which gives the plant its name. There are 10–50 spikes per culm, and in each spike there are three to six spikelets, or rarely as many as 10. Each spikelet is long and consists of two glumes and two florets. One of the florets is fertile, and has colorful orange to brownish red anthers and feathery ...

Aristida Purpurea
''Aristida purpurea'' is a species of grass native to North America which is known by the common name purple three-awn. Distribution This grass is fairly widespread and can be found across the western two thirds of the United States, much of southern Canada and parts of northern Mexico. It is most abundant on the plains. Description This is a perennial bunchgrass, growing erect to under a meter-3 feet in height, and the flower glumes In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and ... often assumes a light brown to reddish-purple color. There are several varieties with overlapping geographical ranges. This is not considered to be a good graze for livestock because the awns are sharp and the protein content of the grass is low.

Bothriochloa Saccharoides
''Bothriochloa saccharoides'' is a species of grass known by the common name silver bluestem. It is native to the Americas, including Mexico, the Caribbean, and parts of Central and South America. This perennial bunchgrass grows to 2 to 3 feet in height. The leaves reach 8 inches long. The stems are often purplish toward the base. The inflorescence is white and hairy.

Amorpha Canescens
''Amorpha canescens'', known as leadplant, downy indigo bush, prairie shoestring, or buffalo bellows, is a small, perennial semi-shrub in the pea family (Fabaceae), native to North America. It has very small purple flowers with yellow stamens which are grouped in racemes. Depending on location, the flowers bloom from late June through mid-September.Penskar, M.R. 2008. Special Plant Abstract for leadplant (Amorpha canescens). Michigan Natural Features Inventory, Lansing, MI. 4 pp. The compound leaves of this plant appear leaden (the reason for the common name "leadplant") due to their dense hairiness. The roots can grow up to deep and can spread up to radially. This plant can be found growing in well-drained soils of prairies, bluffs, and open woodlands. Description Typically between tall, leadplant can be identified by its small purple flowers grouped in long spikes and its grey-green leaflets that are alternate and pinnately compound.

Sporobolus Heterolepis
''Sporobolus heterolepis'', commonly known as prairie dropseed, is a species of prairie grass native to the tallgrass and mixed grass prairies of central North America from Texas to southern Canada. It is also found further east, to the Atlantic coast of the United States and Canada, but is much less common beyond the Great Plains and is restricted to specialized habitats. It is found in 27 states and four Canadian provinces. Description Prairie dropseed is a perennial bunchgrass whose mound of leaves is typically from high and across. Its flowering stems ( culms) grow from tall, extending above the leaves. The flower cluster is an airy panicle long with many branches. They terminate in small spikelets, which each contain a single fertile floret. When it blooms, the floret has three reddish anthers and a short feathery stigma. If it is pollinated, the floret produces a nearly round seed long. At the base of the spikelet are two bracts (glumes), one of them long and ...
