122. Recommend consultants or agencies to research and analyLe
key habitats.
Field work may be coordinated through the Fish end Wildlife
Service and the seven state wildlife agencies in the basin.
Specialised research problems may be delegated to con-
tractors and sponsored by a•resource management agency.
13. Establish critical habitat under Section 7 of the Endangered
~ecies Act. •
Based on analyses of habitat requirements and location of occupied
and potential habitats, critical habitat can be reco®ended.
Note that actual designation of critical habitat is a legal
process; only the Secretary of the Interior has authority to do
this.
2. protect and~manatte the humpback chub and its habitat so wild popula-
bans are increased and/or maintained. •
If the recovery program is to succeed some populations and habitats
of the humpback chub must be stabilized and others should be increased.
Combined with knowledge of what good humpback chub habitat is, popula-
tion levels must be researched and manipulated and the critical
habitats protected and restored via habitat management plans.
21. Locate all existing populations by conducting species inventories
in suspected habitats.
Only four populations are currently known, due to the difficulty
of getting access into deep canyon-bound rivers and the in-
efficiency of sampling techniques. Other populations may exist
in areas like Cross Mountain Canyon on the lower Yampa River or
Cataract Canyon on the Colorado River. The existence of the
humpback chub must be documented to offer the habitat legal
protection.
22. Determine ulation status and levels needed to maintain five
secure populations.
To manage and maintain viable humpback chub populations, the
characteristics of a "healthy" population must be described.
Very little is currently knows about such population descriptors.
