This study of dissolved inorganic nitrogen is located in a regenerating clearcut area along Little Lost Man Creek, Redwood National Park, California. Factors affecting fluctuation of nitrate concentration in experimental channels include storms, time of day/night, age of the benthic community, and changing canopy cover. The study suggests that production related to nitrogen will decrease as the alder canopy matures until natural mortality reopens the canopy. The riparian vegetation is thus important in nitrogen cycling in the creek, affecting fish as well as other aquatic life. Establishment of dense alder stands is common after logging, and more research is suggested on long-term impacts of this kind of land use. Includes diagram of method, graphs (nitrate data), and tables (biological and physical factors, channel properties of experimental flumes).
