Description
The restricted soil depth, droughty conditions, and native grasses made them susceptible to frequent fires, once every 3 to 5 years. Consequently, fire-tolerant oak dominated the open-canopy overstory, and the understory consisted of a dense cover of native grasses and forbs (Community 1.1). During fire-free intervals, eastern redcedar, along with hickories and oak sprouts, increased in abundance and competed with the herbaceous ground flora, creating more brushy woodland (Community 1.2). However, the return of fire would re-open the woodland and promote the ground flora.
