The Schuylkill and Susquehanna railway corridor formed the basis of one of America’s first rails-to-trails, and exists today as a nearly 20-mile path across isolated woodlands. The history of this valley, which lies adjacent to the Appalachian Trail, is a microcosm for much of the coal country of central Pennsylvania.In the 1740’s, Moravian Christian missionaries

Harry Potter fans might recognize this plant from a seveth-century Italian herbal: it is a mandrake, or in Latin, “mandragora.” So named because Ancient and Medieval Europeans thought the way that its root resembles a man (or a woman, see illustration three) was just so extra, the mandrake gained a reputation for producing effects far

The Dolly Sods Wilderness Area in West Virginia is almost 72 square kilometers of protected lands. The ecology is unique — much of the area is between 2,000 and 4,000-foot elevation, and is filled with high-altitude marshy bogs, red spruce forests, and windswept boulders. But it did not look like this 100 years ago.In the

It fits that the grave of Carl Bosch in Heidelberg is overgrown with the competing green textures of the jumble of plants collecting at his tombstone. Plants were something Bosch understood more than most people — and that, combined with his engineering skills, got him the Nobel Prize in Chemistry in 1931. A just reward,

A lovely chapter in human history was undertaken with the formation and development of south-eastern Virginia’s Back Bay Natinal Wildlife Refuge. Formed in 1938 to provide a safe migration zone for migratory bird species, the Back Bay NWR was doubled in size to include over 9,000 acres in the 1980’s as the Virginia Beach area

Where I live in south-central Pennsylvania, farmers and outdoor enthusiasts are well aware of new invasive species posing a threat to our forests and crops, like the Emerald ash borer and the Spotted lanternfly.

Fowler’s State Park is another example of the good work done to heal clearcut land and create wild spaces during the Great Depression.
