Conservation threat assessment of Commiphora wightii (Arn.) Bhandari - an economically important species.

Abstract

In the present study, habitat, distribution and regeneration of Commiphora wightii (Arn.) Bhandari (Burseraceae) was explored in Rajasthan, India, to support conservation actions. Twenty-six sites were identified for sampling the populations of C. wightii in the desert region and in Aravallis. Commiphora wightii prefers rocky substratum and grows in shallow, gravelly, unfertile soils, hilly terrains and under open canopies. The number of saplings was only 5.68% as compared to its adult population. Population densities of C. wightii were 25 stems ha-1 in desert and 40 stems ha-1 in Aravallis of Rajasthan, India. Over-exploitation, narrow extent of occurrence, small area of occupancy, severe fragmentation of populations, very low regeneration and invasion of alien species to its habitat revealed that C. wightii is facing severe conservation threat and extinction risk. It should be prioritized for "endangered category" by ensuring the habitat conservation, sustainable utilization and cultivation of this economically important species.
