About this file
This file is a seed mix specification document for Buckley Space Force Base in Colorado, detailing four distinct native grass and wildflower seed formulations designed for different landscape conditions. The seed mixes are specified in Pure Live Seed (PLS) pounds per acre, with each mix totaling 25 pounds per acre. The Shortgrass Species mix contains eight grass varieties including western wheatgrass, buffalograss, and blue grama, optimized for arid environments. The Tallgrass Species mix incorporates thirteen species including sand bluestem, big bluestem, and indiangrass, with two wildflower species (large-flowered penstemon and Rocky Mountain penstemon) noted as subject to availability. The Overflow Drainage Species mix comprises nine species including prairie cordgrass and switchgrass, formulated for areas with seasonal water accumulation. The Wetland Species mix contains ten species including various sedges and mannagrasses, with fowl mannagrass and large-flowered penstemon flagged as subject to availability at the time of order, with omission if unavailable.
No pricing, contract terms, delivery dates, or procurement requirements are specified in this technical specification document. The seed mixes appear to be part of a landscape restoration or grounds maintenance project for the facility, with species selections reflecting Colorado's climate zones and soil conditions. The availability contingencies for certain species suggest flexibility in procurement to accommodate seasonal or stock limitations from seed suppliers.
