Fire Decreases Arthropod Abundance But Increases Diversity: Early and Late Season Prescribed Fire Effects in a Sierra Nevada Mixed-Conifer Forest
Pages: 79-102
DOI: 10.4996/fireecology.0202079

Prior to fire suppression in the 20th century, the mixed-conifer forests of the Sierra Nevada, California, U.S.A., historically burned in frequent fires that typically occurred during the late summer and early fall. Fire managers have been attempting to restore natural ecosystem processes through prescription burning, and have often favored burning during the fall in order to mimic historical fire regimes.  [Read More]

Shrub Seed Banks in Mixed Conifer Forests of Northern California and the Role of Fire in Regulating Abundance
Pages: 32-48
DOI: 10.4996/fireecology.0801032

Understory shrubs play important ecological roles in forests of the western US, but they can also impede early tree growth and lead to fire hazard concerns when very dense.  Some of the more common genera (Ceanothus, Arctostaphylos, and Prunus) persist for long periods in the seed bank, even in areas where plants have been shaded out.  To determine shrub seed density and investigate the feasibility of managing shrub abundance by regulating the size of the soil seed bank with fire, we sampled the seed bank in 24 mixed conifer forest stands throughout northern California.  [Read More]
