IDU: What is Pando and why is it shrinking?

There is an area in Utah consisting of over 40,000 individual aspen trees spreading over 160 acres.
It is believed to be the largest, most dense organism ever found at nearly 13 million pounds.
It is called the Pando clone and specialists are concerned because the clone is showing signs of decline.
What is the significance of Pando? What are the causes of the decline? And what can humans do to help it regenerate?
Director at the Western Aspen Alliance Paul Rogers joins William Shatner on this week's episode of 'I Don't Understand' to explain Pando.
