2] Natural pieces of wood enhance habitat conditions
and promote key ecosystem functions in streams. Wood
pieces provide stable substrate for invertebrates and biofilms,
entrap leaves and other organic matter, afford overhead
cover for fish, promote hyporheic exchange flow and
transient storage, enhance hydraulic heterogeneity, and
encourage pool formation and channel meandering
[Angermeier and Karr, 1984; Beechie and Sibley, 1997;
Gregory et al., 2003; Johnson et al., 2003; Mutz and Rohde,
2003; Eggert and Wallace, 2007; Stofleth et al., 2008]. The
frequency and character of wood inputs varies in space and
time [Latterell and Naiman, 2007; Golladay et al., 2007]
and is strongly affected by riparian management [Flebbe
and Dolloff, 1995; Angradi et al., 2004; Kreutzweiser et al.,
2005; Czarnomski et al., 2008].
