Critical habitat for a listed species contains Primary Constituent Elements (PCE's), as defined below. ' Primary Constituent Elements: In accordance with Section 3(5)(A)(i) of the ESA,and regulations at 50 CFR 424.12(b),in determining which areas occupied at the time of listing to propose a critical habitat, we consider the physical or tbiological features essential to the conservation of the species and that may require special management considerations or protection. These features are the PCE's laid out in the appropriate quantity and spatial arrangement for conservation of the species. These include, but are not limited to: (1) Space for individual and population growth for normal behavior. (2) Food, water, air, light, minerals,or other nutritional or physiological requirements; (3) Cover or shelter;(4) Sites for breeding, reproduction, or rearing (or development) of offspring; and (5) Habitats that are protected from disturbance or are representative of the historical, geographical, and ecological distributions of a species. Essential habitat types for salmon and steelhead species can be generally described to include the following: (1) juvenile rearing areas; (2) juvenile migration corridors; (3) areas for growth and development to adulthood; (4) adult migration corridors; and (5) spawning areas. Within these areas, ' essential features of critical habitat include adequate: (1) substrate, (2)water quality, (3)water quantity (4) water temperature (5)water velocity, (6) cover/shelter, (7) food, (8) riparian vegetation, (9) space, and (10) safe passage conditions.
