* Should one or more of the species in Table 2.05-7 be unavailable or proven ineffective, then substitutes from
this list will be selected in the priority stated. They will be placed in the seed mix at the rate specified in the
priority stated. They will be placed in the seed mix at the rate specified for the unavailable/unsuitable species or
as appropriate. If more than one species of a given lifeform cannot be obtained or is otherwise unsuitable, then
the first and second priorities in the substitute list will be used. Colowyo can also choose to increase a seeding
rate of an approved species if a corresponding substitute is not available rather than choose a substitute from
Table 2.05-8. Colowyo will obtain prior verbal approval from the CDRMS.
