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