NOAA-NMFS-NWFSC TM-35: Chinook Status Review

Appendix E (Cont.).
 

NOTES

?

Not an ESA issue (chinook salmon were not historically present in the watershed or current stocks are not representative of historical stocks).

¤

Denotes recent abundance mapped in Figures 28 - 45.

*

Denotes long-term trend mapped in Figures 28 - 45. (Only data with an adequate time series were mapped.)

¹

Run timing designations: Fa -- fall; Sp -- spring; Su -- summer; Wi -- winter (as reported by data reference).

²

Production: (as reported by data reference).

Status summaries from the following sources:

A--Nehlsen et al. (1991):

E, endangered (US); X, extinct; A+, possibly extinct; A, high extinction risk; B, moderate extinction risk; C, special concern.

B--Higgins et al. (1992):

A, high risk of extinction; B, moderate risk of extinction; C, stock of concern.

C--Nickelson et al. (1992):

H, healthy; D, depressed; S, special concern; U, unknown.

1, May not be a viable population; 2, Hatchery strays; 3, Small, variable run.

D--WDF et al. (1993): Three characters represent stock origin, production type, and status, in that order.

Origin: N, native; M, mixed; X, non-native; U, unknown; -, unresolved by state and tribes.

Production: W, wild; C, composite; A, cultured; U, unknown; -, unresolved.

Status: H, healthy; D, depressed; C, critical; U, unknown.

E--Huntington et al. (1996):

H-I, healthy Level I (abundance at least two-thirds as great as would be found in the absense of human impacts).

H-II, healthy Level II (abundance between one-third and two thirds as great as expected without human impacts).

⁴

Petition status [P?]: Indicates (by 'P') stocks included in the ONRC and Nawa petition dated 31 January 1995. Parentheses indicate stock is included as part of a larger unit in the petition.

⁵

Data Type Codes: AC, angler catch expanded (1988-92); CS, carcass; DC, dam count; FM, fish per mile; HE, total estimated hatchery escapement; IT, index total; PC, peak or index live fish, surveys combined; PI, peak or index live fish; PR, peak redd count; RC, redd count; RH, resting hole counts; RM, redds per mile; RMC, redds per mile (surveys combined); SC, spawner counts; SN, snorkle counts; TC, trap count; TE, total estimated escapement (includes hatchery escapement only for mixed production type); TL, total live fish count; WC, wier count.

⁶

Most recent 5 years of data used to calculate spawning escapement geometric mean. (Expanded angler catch = 1988-92).

⁷

Trend (Long-term): Calculated for all data collected after 1950.

⁸

Short-term Trend: Calculated for most recent 7-10 years during the period 1987-96, except as noted.
