Question: How do interactions between rocky landscape fea-
tures and fire regime influence vegetation dynamics?
Location: Continental Eastern USA.
Methods: We measured vegetation, disturbance and site char-
acteristics in 40 pairs of rocky and non-rocky plots: 20 in
recently burned stands, and 20 in stands with no evidence of
recent fire (`unburned' stands). Two-way analysis of variance
(ANOVA) was used to assess the main and interaction effects
of fire and rock cover on plant community composition.
Results: In burned stands, rock cover had a strong influence
on vegetation. Non-rocky `matrix' forests were dominated by
Quercus, and had abundant ground cover and advance regen-
eration of early and mid-successional tree species. Burned
such as Acer rubrum, Sassafras albidum and Nyssa sylvatica
and had little advance regeneration or ground cover. Quercus
