Dynamics: Quercus emoryi is well-adapted to recurrent fire. It is a vigorous sprouter from the root crown or stump following fire (Carmichael et al. 1978). Historically, fires probably occurred every 10 to 20 years in oak woodlands (Baisan and Swetnam 1990). The estimated fire regime for the Madrean oak-pine woodland is probably a fire-tolerant, fire-maintained community (Swetnam et al. 1992). Recent or frequent past fires could reduce the conifers and increase shrub components. Vegetation would resemble chaparral. Arctostaphylos pungens does not sprout from the roots or crown following fire. It is a prolific seeder in response to fire. Such seed crops can be stored in the soil for decades. Arctostaphylos pungens communities are characteristic of frequently burned areas with dry, coarse soils and are typically found in the transition zone between chaparral and pine or oak woodlands.
