Invasive Pests Kill Enough Trees To Hamper Carbon Storage

In addition to the ecological impact, the devastation invasive pests wreak on trees reduces carbon storage equivalent to the amount of carbon emitted by 5 million vehicles each year.

Invasive insects and pathogens have wreaked havoc on ash, elm, chestnut, and other trees, wiping some almost completely from American forests.

The trees the 15 most invasive pests kill each year contain 5.53 teragrams of carbon (TgC), equivalent to about 6 million US tons.
