• Coarse Textured Sites: All species except Agropyron smithii <br />PLS - is the pure live seed content or percentage found in bulk seed. PLS is calculated by <br />multiplying the germination rate times the purity rate. Example: a seed tag listing alfalfa <br />as being 99 percent pure having a 91 percent germination rate would have a pure live seed <br />rate of 90 percent as seen by: <br />.99 x .91 x 100 = 90.09 PLS <br />Because purity and germination rates vary with each growing season and seed producer, the <br />seed rates listed in the Revegetation Plan are PLS rates (instead of bulk rates which vary <br />greatly due to variations in purity and germination). <br />Seed Mix #2 -Reclaimed Drainage/Mesic Site Mix <br />Species <br />Scientific Name <br /> Drilled <br /> Rate lbs. <br />Common Name PLS/ acre* <br />Thickspike wheatgrass 4.0 <br />Western wheatgrass 5.0 <br />Slender wheatgrass 4.0 <br />Smooth brome 3.0 <br />Alfalfa, prostrate type 1.0 <br />Canada bluegrass 0.5 <br />Alkali sacaton 1.0 <br /> 18.5 <br />1.

These areas include spillway areas, low water lines, affected drainageways <br />and other associated disturbance areas exhibiting mesic conditions. <br />The following varieties are recommended for the species included in Seed Mix #2: <br />Common Name <br />Recommended Variety <br />• REVISED 3-19-98 <br />22-4 <br />
