Fire is an integral component of many temperate and tropical eco­systems, but it can be disruptive when it occurs in normally fire-free environ­ments. Tropical deciduous forests in India have experienced annual anthro­pogenic fires for hundreds of years. We examined the effects of anthropogenic fires and fire exclusion on the stature of juvenile trees (_<1.5 m) in a tropical deciduous forest in central India. Plots burnt for 2 consecutive years showed no difference in juvenile size-class distribution before and after the treatment was imposed, while the juvenile trees in plots protected from fires showed a significant increase in height and attained greater stature. In plots protected from fire, juvenile trees exhibited some die-back as a result of dry season drought; however, the proportion of juveniles that died back was significantly smaller than the plants that experienced die-back in burnt plots. Relative growth rate of juvenile trees was significantly greater in unburned plots than in plots burned consecutively for 2 years (P < 0.05). Thus, our results suggest that anthropogenic fires stunt the growth of juvenile trees.
