The concept described in this paper explicitly incorporates both ecological integrity (maintaining function) human values (what society the ecosystem). Stream ecologists who want their research contribute improving conditions flowing waters require concepts like health, which will stimulate directions be more effective restoring preserving unique organisms ecosystems they study. Determining what a requires integration of ecology with disciplines such as economics political science, because health must take into account attitudes social institutions are part stream's watershed. New fruitful for lie developing operational measures include dimension move beyond identifying symptoms stress, elucidating processes actions maintain health.
