They will be placed in the seed mix at the rate specified in the <br />priority stated. They will be placed in the seed mix at the rate specified for the unavailable/unsuitable species. If <br />more than one species of a given lifeform cannot be obtained or is otherwise unsuitable, then the first and second <br />priorities in the substitute list will be used. Colowyo can also choose to increase a seeding rate of an approved <br />species if a corresponding substitute is not available rather than choose a substitute from Table 2.05-8.
