SEED MIX:

EXECUTION

3.01 SITE REHABILITATION:

A. Soil - All disturbed areas shall be left in a de-compacted roughened state; friable, and loose to 6 inch depth. Native topsoil shall be removed from areas prior to disturbance, stockpiled and re-spread after final subgrade is achieved. Any fill required to bury in place any foundation material shall be mineral sub-soil. If fill material is required from beneath vegetated areas; existing topsoil and vegetation will be removed first and stored on site for redistribution after final grade is achieved. Conserved topsoil shall be used to amend previously non-vegetated areas where buildings were located.

B. Invasive plants - To prevent introduction of weeds, no agricultural mulch shall be permitted. All equipment entering site must be sanitized, by removing all dirt clods and vegetation debris from all areas of the equipment. Steam or chemical sanitization may be required to prevent infesting the site with invasive plants and pathogenic organisms. The USFS may treat extant weeds prior to implementation of the contract, and exclude activity from areas of current infestation.

C. Seed – Seed shall meet seed mix requirements. The seed shall be uniformly distributed at the specified rate through hand broadcasting. Seed broadcasting may take place between Sept 15 and May 15. Seed shall not be broadcast over snow deeper than two inches, and should be broadcast just prior to ground freeze up.

3.02 SEED MIX

A. Contractor shall provide a seed analysis test for each lot and should be able to provide the results. The Forest Service will not accept any seed lot that has any cheatgrass (0% cheatgrass permitted)

B. For each seed lot the vendor must provide both the “purity” and “viability” (PLS) and “noxious weed exam” lab results from the seed analysis test. Purity assesses the species you ordered and is based on a smaller sample; noxious assesses the listed noxious weed seed and is based on a larger sample. Weeds may show up in both results. These two tests shall list all weeds encountered and searched for regardless of if noxious or not (“common weed”).

C. To find where weeds appear on seed analysis results, look in each of these three reports sections;

a) Noxious

b) Weed/common weed

c) Crop/other crop

D. Seed must be “certified”

-Purity and Viability (PLS) - (assesses what you are paying for and crop/common weed)

-Noxious weed exam – (all states Noxious (except Hawaii) or Western States Noxious (only tests Western US) or Gold standard to best reveal weeds = order “bulk exam for weed and crop” = tests a larger portion of submitted sample for all weed seeds and crop seeds regardless of noxious legal status.

Forest Service personnel will review the seed test analysis of all seed lots to see if there are any concerns with any species that came up in the test results before seed is purchased and seeded. Forest Service will not accept any seed lot that has prohibited noxious weed seed and is unwilling to accept any weeds; cheat grass or other annual Brome. Forest Service would prefer 0% restricted noxious weed seed presence in any of the seed lots purchased. Forest Service has the right to decline a seed lot if a weed/crop seed is determined to be a resource concern if planted on Forest Service lands. Seed lots that have test dates for viability, Purity and weed content older than 13 months will not be accepted.
