The 6th Asian Dendrochronology Conference was held at Lucknow.
This is the first time that the conference is being held in India.
Dendrochronology is the study of tree rings.
Tree rings hold a wealth of information about not only a tree’s past but also that of the ecosystem in which it lives.
Scientists at the conference have said that “Reconstructions of past responses of vegetation from different ecosystems can predict the impact of climate change”.
