It is evident that there is a steady seasonal decline in silica-free ash. Silica, which is of no value in animal nutrition, is abundant in these grasses, and its presence masks the trend of the other mineral elements when no separate determination of silica-free ash is made. Grasses of Secondary Importance There are several native grasses which occur commonly in the Shortgrass Prairie area but which are not sufficiently abundant to rank with the dominant species discussed previously. Some are scattered throughout the uplands, while others are localized in areas where conditions of soil moisture, salt concentration, etc., differ from those prevailing in the zone generally. These species may con- tribute a considerable proportion of the grazing in certain areas or at certain seasons of the vear. The data for some of these forms are summarized in Table 8.
