Here, But Functionally Gone

Extinction. The end of a species; no coming back. Many conservation efforts strive to save species from this fate, and a species’ risk of extinction can also be a major factor in determining its listing as endangered. A recent study published in Nature suggests, though, that we may want to pay a bit more attention […]

European Ash to Ashes?

By Marcelene Sutter European ash trees cannot seem to catch a break. Currently, an ash dieback fungus caused by Chalara faxinea has been plaguing Europe, requiring research funds and the efforts and attention of scientists. Now, another threat to these trees looms on the horizon. As readers of American Forests magazine know from the Winter […]

The Rise and Fall of Champions

Relative to humans, most tree species live a long time. Many of the trees we have personal connections to have been around long before us; some of the oldest trees have been here longer than the pyramids of Giza, perhaps even longer than Stonehenge. It might seem like we couldn’t possibly watch these giants rise […]

It’s World Animal Day

By Lizzie Wasilewska On October 4, 1931, a group of Italian ecologists founded World Animal Day with the hope of drawing attention to threatened wildlife.

The Serious Business of Leaf Peeping
