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 or <br />as appropriate. If more than one species of a given lifeform cannot be obtained or is otherwise unsuitable, then <br />the first and second priorities in the substitute list will be used. Colowyo can also choose to increase a seeding <br />rate of an approved species if a corresponding substitute is not available rather than choose a substitute from <br />Table 2.05 -8. Colowyo will obtain prior verbal approval from the CDRMS. <br />Page 4 -2 <br />
