Game (Little and McKirdy). New Mexico has also pro-
hibited bait fishing for this species as they are quite
susceptible to over exploitation.
c) Colorado DOW has attempted to restock this subspecies in
at least one lake in the Colorado River drainage. Lloyde
Hazzard (DOW) reports this transplant was unsuccessful.
Attempts at hatchery rearing in Colorado and New Mexico
have also met with little success. '
5. BLM Interest
a) Inventory - All highland streams flowing through National
Resource Lands in the Rio Grande drainage should be sur-
veyed for pure strains of Rio Grande cutthroat trout
and/or streams that would be suitable for reintroduction
after renovation. At present no trout of this subspecies
are known to be maintaining populations on NR Lands.
b) Management - If and when stocks and suitable habitats are '
located, all efforts should be made to maintain them in
conditions most favorable for S. c. virginalis. State
DOW personnel will be asked to assist in the development
of a Habitat Management Plan to maintain stock purity
and increase population size. Eventually, several iso-
lated streams in diverse portions of the drainage should
be managed solely to perpetuate this subspecies.
