DNA barcoding technology helping monitor health of all-important boreal forest. The Boreal forest is essential to Canada and the world, storing carbon, purifying water and air and regulating climate. But keeping tabs on the health of this vulnerable biome has proven to be a painstaking and time-consuming undertaking - until now. Cutting-edge DNA metabarcoding technology can help speed up and improve the monitoring process, according to a new study. Source 1k.
