Varies Season: The species composition of grassland varies season widely from location to location, climate to climate, and season to season. The composition of an individual community depends upon the availability of seeds or other propagating materials and their ability to establish themselves, develop to maturity, reproduce, and reestablish and persist in a now-existing vegetation. In many situations various herbaceous plants other than grasses may form a significant part of the grassland vegetation, particularly during a portion of the season. In the spring, for example, semidesert and alpine grasslands contain many broadleaf herbs.
Increase or decrease the frequency of mowing according to the rate of growth, which varies season from season to season, and may be influenced by bad weather, feeding, irrigation, the varieties of grass being grown and the general health of the turf itself.
Different types of lawn require a different frequency of mowing. Fine lawns, for example, should be mown every two to three days,
average lawns at least every seven days and preferably at intervals of three to five days and, for other sod lawns, mow at least once a week.
Climate is an important factor in determining the location and development of grassland and its composition and production. Most other factors are conditioned by climate, or they result in the modification of the local climatic influence. Topography and elevation are such factors. Climate is not static. Its influence on grassland varies season widely from place to place, season to season, day to day, and even within the day and night hours. Adjacent areas may have quite different conditions of microclimate, which in turn influence plant adaptation and thus the grassland species association. Wide differences occur between and within grassland types. |
