Amphibian Species Characteristics Sample Clauses

Amphibian Species Characteristics. The southern torrent salamander and tailed frog are alike in that: • Both are found primarily in perennial watercourses and colder water relative to the salmonid species; • Larval stages of both prefer xxxxxx habitats that have clean cobble and gravel with minimal sediment accumulation; • Both have limited dispersal abilities and are seldom found outside the stream or riparian strip; and • Under certain circumstances, both can persist in streams with temporary periods of no flow or segments of subsurface flow during the late summer and early fall.

Schematic profile of the Covered Species distribution along a hypothetical stream channel. Figure 3-1 is a generalized view of the distribution of the Covered Species within a hypothetical sub-basin in a coastal California watershed. The limits of each species’ distribution in regard to channel gradient and distance upstream are not to scale, and smaller tributaries are not accounted for. Table 3-1.
