Secondary Production
After 4 years, total secondary production in mixed substrate habitats (cobble, pebble, and sand-silt) had decreased by 78% compared to pretreatment values, demonstrating a strong impact of the exclusion of terrestrial detritus (Wallace et al. 1999). However, secondary production of invertebrates living on moss-covered bedrock was not affected.
