When broadcasting the seed, the pounds per acre noted below are to be doubled. The contracting officer is to be notified a minimum of seven (7) days prior to seeding of the project.

Seed Mixture ‐ Western wheatgrass and Wyoming big sagebrush must be included in the mix.

Thickspike wheatgrass or Montana wheatgrass may be substituted only when western wheatgrass is unavailable. The combination of seed must include all growth forms (grasses, forbs, and shrubs).

The percent of each species is the maximum percent of the total mix for example on a clayey site the various grasses listed make up 80% of the total seed mix, therefore individually western wheatgrass may account for no more than 25% of the total seed mix. The seed mixture shall be planted in the amounts specified at a rate of 30‐50 small seeds plus 20‐25 medium seeds plus 15‐ 20 large seeds per square foot; totaling 65 to 95 live seeds per square foot, or 2,831,400 to 4,138,200 live seeds per acre. Seeding should be completed between October 15 and May 15, when conditions are appropriate.

To calculate total amount of Pure Live Seed needed per acre for each species:

[(Pounds of Pure Live Seed/acre) x (percent of mix)] / [(Germination rate) x (Purity of seed)] Add totals for each species to be planted and multiply by the number of acres to be seeded to determine the amount of seed necessary for the proposed project area.
