Litter Production by Red Alder in Western Washington
Abstract:Litter production was measured with four 45.7² cm traps per stand for 8 to 9 years in seven 30-year-old red alder (Alnus rubra Bong.) stands. Production between years did not differ significantly except for one in which buds and twigs were severely damaged by frost the previous November. The wetness of the summer in a given year affected timing and amplitude of the annual production peak. Annual nitrogen return was from 80 to 200 kg ha-1 yr-1 Forest Sci. 20:325-330.
