Table 4 Fixed effects in a mixed model analysis of variance of number of shrub seeds 0.01 m−3 (1 m2 × 1 cm depth) of the three most common genera (Ceanothus, Arctostaphylos, and Prunus) in six layers from the top of the forest floor to 10 cm into the soil with and without prescribed burning at two sites (McCloud and Jennie Springs) in northern California. Treatments at the two sites were: McCloud—fall (October) burn and control; Jennie Springs—fall (October) burn, early summer (July) burn, and control. Degrees of freedom (df) are shown for both the numerator and the denominator.
