Abstract

Lantana camara L., a serious threat to the tree regeneration in Garhwal Himalaya.

Abstract

Invasive alien species are a product of the ongoing and increasing re-distribution of species, by human to support agriculture, forestry, horticulture and recreation, as well as a result of accidental introductions. Lantana (Lantana camara L.) is a multi-stem or branched thicket originated from tropics and subtropics of America infested many forest communities of the Southern part of Garhwal Himalaya. The results of the present study showed that its density is severely increasing in sub-montane part while approaching the higher montane part of the region. Local tree regeneration was greatly affected by this invasive species. Communities where its density was higher, the regeneration (seedlings and saplings) of trees was lower. Soil analysis revealed that its growth and dominance was higher in organic carbon rich containing soil. Nitrogen content was also higher in Lantana abundant sites.
