29 <br />• Observations of the plots after another growing <br />season will give an even better estimate of the species <br />composition and seeding rates for revegetation of large- <br />scale disturbances. <br />Table 6. Density by species measured on 10 August on plots <br />seeded to species mix on 24 May 1978. <br />S ecies Seeded Density 2 Plant Density <br />p Pure live seeds/ft Plants/ft2 <br />Prairie sandreed 10 0.71 <br />Blue grama, Covington 5 2.36 <br />Western wheatgrass, 5 0.27 <br />Arriba <br />Sideoats grama, Vaughn 2 0.20 <br />Sand dropseed 1 2.05 <br />Sand bluestem 1 0.12 <br />Little bluestem 1 0.05 <br />Indian ricegrass 1 0.01 <br />TOTAL 26 5.77 <br /> <br />Sod Transplanting <br />Certain desirable species growing on the Deep Sand Site <br />are rhizomatous (spread and sprout from underground stems) <br />and thus might be possible to reestablish by transplanting <br />with topsoil. These species include prairie sandreed, sand <br />bluestem, and western wheatgrass. So an attempt was made <br />to simulate transplanting in a topsoiling operation by using <br />a front-end loader to scoop up sod to a depth of about <br />8 inches and redeposit it over subsoil. In the front-end <br />loader operation the vegetation growing in the sand (moist <br />at the time) did not hold together as a mat, and thus was <br />dumped as a jumble of sand, roots, and tops. The deposited <br />topsoil was mulched, and received 0.8 inches of precipita- <br />tion over the period of 25 May (transplanting date) to <br />5 June. On 6 June regular sprinkler irrigation was started. <br />Very few transplants can be found. Thus it appears <br />• unlikely that many plants will be reestablished from rhizomes <br />in topsoil. <br />
