Abstract

Studies were undertaken in ten and twenty year old pure stands of Acacia auriculiformis along with twenty year old mixed stand with dominance of Enterolobium cyclocarpum in Auroville, South Arcot District, Tamil Nadu.

The diversity of species and the number of seedlings sprouting under tree stands differed with overstorey vegetation. The mixed stand favoured more diversified indigenous regeneration than pure stands of A. auriculiformis.

The diversity index for regenerating seedlings was greater in mixed stand (0.356) than in ten and twenty year old pure stands of A. auriculiformis (0.193 and 0.096 respectively).

Abundance of established seedlings of A. auriculiformis was greater in ten year old pure stand (14.8 per sq. m) than in twenty year old stand (10.9 per sq. m) and was least under mixed stand (6.8 per sq. m).

The accumulated litter layer (with annual litter production ranging from 10.4 to 14.0 t/ha) and dense canopy of A. auriculiformis stands favoured less the establishment of indigenous species and at the same time it encouraged its own progenies to establish in its shade.
