Bring fact-checked results to the top of your browser search. Economic and ecological importance Grasses dominate large expanses of the middle of continents, such as the North American prairies, South American pampas, African veld, and Eurasian steppes.
No single climate generates grasslands ; they develop in areas with wide ranges of rainfall from semiarid to subhumid and temperature. Native grasslands develop where there are frequent fires and droughts, level to gently rolling topographyand in some instances grazing animals and special soil conditions.
Fire is pervasive in natural grasslands—early settlers of the North American grasslands, for example, recorded spectacular annual fires—and beneficial in that a fire recycles nutrients bound in dead plants into the soil for use by living plants.
Persistence of grasslands depends on the exclusion of competing woody species that would supplant the grasses. Because fires tend to occur most readily during dry seasons when grass roots, rhizomes, and seeds are protected in the soil and woody plant stems are fully exposed, they tend to do more damage to woody plants than to grasses.
Fire alone, however, will not maintain grasslands, because some trees are tolerant of fire. Periodic drought damages the exposed stems of woody vegetation more than the buried underground parts or seeds of grasses. Further, the composition of grasslands has been partially regulated by large herbivores, such as the buffalo on the North American prairie whose grazing suppresses the invasion of woody plants into the grassland and, like fire and drought, may actually stimulate the growth of grasses.
Often, a small number of species dominates a grassland. For example, on the true North American prairie, which stretches from southern Manitoba to Texas and forms the eastern edge of grasslands in North AmericaAndropogon gerardi big bluestemSchizachyrium scoparium little bluestemSporobolus heterolepis prairie dropseedand Stipa spartea porcupine grass are the primary grasses.
These species occur in varying proportions and are joined by other grasses, depending on climatic and other factors. Grasses have adapted to the full range of environmental extremes occupied by plants, from the coldest regions and highest elevations where plants grow to equatorial heat, and from fully aquatic habitats to deserts.
These remarkably adaptable plants play significant, sometimes dominant, roles in many plant communitiessuch as freshwater and saltwater marshes, tundras, meadows, and disturbed habitats. In addition, civilization creates temporary habitats for many grasses including not only lawn, pasture, and crop species but also weeds.
Weedy grasses invade and colonize disturbed habitats. While this is not a concern on roadsides, abandoned farmlands, vacant lots, and other low-value land, weedy grasses do seriously devalue cultivated areas such as lawns, pastures, and croplands.
Phragmites australis, for example, is spread vigorously by rhizomes, threatening agriculture wherever there are lowlands or bodies of water near arable fields or pastures.
Natural forces, such as windstorms or fire, may disturb forests and other vegetation not dominated by grasses and thereby open a habitat for weedy grasses. The ancestors of modern weedy grasses may have evolved as a result of such natural disturbances. Except for the woody bamboos, grasses lack the stature needed to compete with trees for light and to elevate their flowers into the forest canopy for wind-dispersal of pollen.ACADEMIC ESSAY Importance of Family in Our Life Family is placed in the centre and top of priority of our life.
Family will take care of our well-being, acts as our role model, and they helps develop our values and identity. Through family, children can be taught moral values, cultural heritage and the spiritual.
