Vines Swamp Southern Forests

A new study in the southeastern U.S. suggests that increased vine growth is changing bottomland hardwood forests. Researchers from Ohio State University charting the growth of grapevines, trumpet vines, poison ivy, and Virginia creeper in two South Carolina forests found as much as a 10-fold increase in just two decades. As the vines increase, the density of small trees decreases, probably because most vines use adhesive roots or tendrils to climb trees. The reasons for the shift aren’t yet understood, but rising CO2 levels may be to blame &mdash since other studies suggest that vines such as poison ivy benefit more than trees from higher CO2 levels. . .

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
