11 <br />Standard Native Seed Mix for Sagebrush and Pinyon-Juniper Zone <br />Mid Elevations (6,000-8,000') <br />This native seed mix should work well in the mid elevation zone in the 11-16" rainfall <br />zone. Use the complete mix on larger projects where substantial amounts of ground will <br />be disturbed, and the likelihood of reseeding from adjacent vegetation is low. On small <br />projects where linear or small patches of vegetation are disturbed and there is abundant <br />adjacent native vegetation for reseeding, use just the bottlebrush squirreltail and <br />western wheatgrass (at 4 Ibs PLS seed for each species per acre, under the drill rate, <br />double this rate for aerial application with no seed incorporation). <br />Price and seed availability vary, so not all species may be available at the time you <br />need them, or priced affordably. However the major ones should usually available. The <br />rate shown below is for a drilled seeding, or some other method that incorporates the <br />seed into the soil. Rates should be doubled if the seed is to be aerially applied. If price <br />or availability is a concern, reduce or leave out those species and increase percentages <br />of remaining species correspondingly (column A in table below, total to this column <br />should equal 100%, carry through changes in columns B, D, and E following instructions <br />under column headings). <br />BLM places the following requirements on seed mixes which are put on BLM lands: <br />1) Use the following minimum PLS Pure Live Seed tolerances <br />PLS tested % Tolerance % oints <br />81-100 -7 <br />61-80 -6 <br />41-60 -5 <br />21-40 -4 <br />0-20 -3 <br />2) All seed must comply with BLM and Colorado weed seed guidelines. There <br />should be no prohibited species seed, and no more than allowable levels of <br />restricted species seed. In addition, there should be no. more that 0.5% total <br />weed seed, less than 2% other seed, and no trash larger than 1/4" in length. <br />Seed shall not be stored in burlap bags. <br />3) The UFO places additional local restrictions on seed to minimize cheatgrass <br />spread. If seed tests show any Bromus tectorum or Bromus japonicus, the <br />BLM should be consulted with for approval. No mix placed on BLM shall <br />contain more than 150 Bromus tectorum and/or Bromus japonicus seeds per <br />pound. <br />4) BLM requires additional seed tests on seeding projects that are greater than <br />20 acres and/or require over 200 Ibs of seed. For these seeding projects, the <br />project proponent should have the seed supply company store the purchased <br />seed prior to mixing, and pull samples to be sent to a certified laboratory, <br />preferably Colorado State Laboratory at the following address. Seed test <br />results must comply with the criteria listed above before seed is mixed,
