243. EncouraR ~•ado tion of legiaiation to vrotact humpback chub <br />populations and their habitat. <br />States aith no authority to protect humpback chubs should <br />press for adoption of meaningful leas. Creation of state <br />Endangered Species Acts, coordination of the activities of <br />several state agencies by executive order, or the power to <br />invoke emiaeat domain may be viable tools to protect <br />endangered species. . <br />25. Pre are habitat mama ement laps to maintain and increase the <br />availabilit4 of keg habitats. <br />Habitat change is the primary factor causing the rarity of hiaapbaclc <br />chubs. Rabitat management is necessary to establish the humpback <br />chub in party of ire former range, that is, to allow population <br />expansion. <br />251. Determine habitat im rovement or maintenance criteria; <br />techniques, and features. <br />Much of the applied research will be conducted under tasks <br />11 and 12. Each management play will no doubt be somewhat <br />unique in responding to the limiting factors for humpback <br />chubs in that area. Examples of suspected beneficial <br />management procedures-are providing optimum flaw during <br />reproductive seasons by manipulating reservoir releases to <br />maintaist•water levels on spawning arena or providing wazmer <br />water during the spawning period by building multi-level <br />reservoir outieta. ~• <br />252. Determine recise sites for habitat restoration or maintenance <br />for existinA-aad potential populations. <br />Closely tied to task 12, the sites with-the best potential <br />to became atabie 1~pback chub habitats will be identified. <br />Habitat management Plans should select at least one ad- <br />ditional site to establish a humpback chub population. <br />19 <br />
