Alkali sacaton, western <br />' wheatgrass, slender wheatgrass, alkali bluegrass, little <br /> bluestem, Canada wildrye, sedges and rushes occur in lesser <br /> amounts. <br /> <br /> Prairie gentian, vetch, bundleflower, wild rose and wild <br />' licorice are also present in small amounts. <br /> Following are percentages, by weight, of the total annual <br /> yield for the potential plant community: <br /> <br /> Grasses and Grasslike Plants: :Percent <br /> Switchgrass----------------------------- 10-30 <br /> Big bluestem---------------------------- 5-15 <br /> Prairie cordgrass----------------------- 5-15 <br />' Indiangrass----------------------------- T-10 <br /> Alkali sacaton-------------------------- 5-15 <br /> Western & Slender wheatgrass------------ 5-15 <br /> Little bluestem------------------------- T-10 <br />' Alkali bluegrass------------------------ T-10 <br /> Sedges---------------------------------- T-10 <br /> Rushes---------------------------------- T-10 <br /> Canada wildrye-------------------------- T-4 <br /> Saltgrass------------------------------- T-6 <br />' Others---------------------------------- T-8 <br />' Forbs: <br />Wild licorice--------------------------- T-4 <br />' Others---------------------------------- T-6 <br /> <br />i~ <br />
