Dhoop or incense is an essential part of all Hindu pujas. It is common that we rarely bother to find out how the dhoop is made or from which tree is the resin extracted. Dhoop or Incense Sticks are made from the resin extracted from Black Dammar (canarium strictum) trees. But sadly due to human greed and over exploitation this tree is on the verge of extinction in Maharashtra . Times of India writes At present, there are just five Black Dammar (canarium strictum) trees in the state," Ankur Patwardhan, head of the bio-diversity department, Garware College , told TOI. Asked the reason for this catastrophic decline in number, Patwardhan said, "The main reason is inhuman practices like cutting or burning of these trees, as these trees have good market value.

According to him, the trees grow well only in crest line areas
