	note = {This paper examines population trends for Pacific herring on the West Coast.  The authors find that overall populations have been declining since the 1980s, although there are areas such as Yaquina Bay that have not seen large declines.  The data hints at cyclic fluctuations in population, but more study is needed.  {\textquotedblleft}We do not understand the drivers of changes occurring in the herring metapopulation, nor have the consequences to upper trophic levels in this marine ecosystem been investigated comprehensively. Expansion of current monitoring and new directed research on relationships between herring and the environment and higher level consumers is therefore warranted and essential.{\textquotedblright} (p.11)},
