The Ultimate Guide to Japanese Barberry: Identification, Medicinal Virtues, Uses, and How to Host a Barberry Pull and Wild Medicine Making Event

Lately, I’ve been exploring how to build relationships with all plants in the ecosystem, including opportunistic (invasive) species and in and in re-orienting our view away from just a human-centric one and re-centering nature. Just like anything else in nature, opportunistic plants have much to offer us, and learning to honor them, their uses, their medicine, and how to work with them is an important part of aligning with our local ecosystem. In today’s post, I want to do a deep dive into one such common opportunistic species throughout Eastern North America – Japanese Barberry (Berberis thunbergii)–and create a comprehensive guide. First, I will share a story of an event I recently hosted in collaboration with two organizations to help remove and educate the public on Japanese Barberry and European Barberry (two opportunistic species listed on Pennsylvania’s Invasive Species list). I’ve had multiple readers ask for how to do this and to share resources to organize.Then, I will will offer resources for this specific plant in terms of identification, harvest, processing, and medicine making.

I have intentionally made this guide very comprehensive with the goal of making this a primer for people who want to offer a similar kind of event. You have my permission to reproduce and adapt parts or all of this post and the additional PDFs and photos to help teach about barberry and the medicine of the plant.

Is Black Walnut Killing Your Plants

“Black walnut kills plants.”

I first heard this statement many years ago. Occasionally, I still hear some version of this claim: Black walnut engages in warfare by releasing a chemical into the soil. This chemical kills or inhibits the growth of plants.

But is this entirely true? Does black walnut actually kill plants?

Some people say yes. Other people say no.

In a brand-new video, I share several key findings from scientific studies and personal observations that shed some light on this controversial topic.

Summer Forest Ecology Outing — New Event Scheduled!

I’m excited to announce that I’ll be leading a Summer Forest Ecology Outing in a few weeks, and I’d love for you to join me!

This outing offers a unique in-person opportunity to learn the fascinating ecology and geology of a remarkable area: McConnells Mill State Park in Pennsylvania.

Designated a National Natural Landmark for its outstanding features, McConnells Mill State Park is a treasure trove for learning. Central to the park’s landscape is the Slippery Rock Gorge — a deep ravine carved by powerful forces, exposing millions of years of ancient bedrock and currently supporting mature forest ecosystems.

During this outing, we will walk through deciduous and coniferous woodlands while discussing forest ecology. We’ll investigate big trees and big rocks. We’ll see historic landmarks, and we’ll discuss important geological influences that have drastically shaped the landscape.

In addition to learning key characteristics of mature forests, participants will learn tree identification techniques, mushroom ecology and identification, the influence of glacial activity on landscape development, ways to interpret forest history, and much more.

This outing is the perfect opportunity to learn, explore, and connect with nature in a truly spectacular setting.

Interested? Here are the details:

When: Saturday, July 12 or Sunday, July 13, 2025 (Choose one date; both programs will cover the same material.)
Where: McConnells Mill State Park, Pennsylvania
Time: 10:00 am — 4:00 pm

To maximize your learning experience, space is limited and registration with payment in advance is required to secure your spot.

I’d love to see you there!

Sunlight and Sage: Welcoming the Summer Solstice

By Beth Schreibman Gehring

Long before calendars and clocks, before schedules and spreadsheets, there were the sun and the stars and those of us who watched them closely—gardeners, healers, farmers, mothers. The summer solstice, the longest day of the year, was a sacred moment. A time of warmth and waiting, of ripening berries and blooming roses, of hands deep in the soil and hearts lifted to the sun.

For me, this day has always held a special kind of magic.

Does Living Near A Golf Course Increase Your Parkinson’s Risk?

Green isn’t always good. In fact, green can sometimes be associated with neurodegenerative diseases.

This is especially true when we take a look at golf courses. Golf courses use heavy amounts of pesticides to maintain uniform conditions. These chemicals kill undesirable plants and insects, but they also weaken human health.

Researchers have known for a long time that pesticides pose significant risks to human health, ranging from acute poisoning to chronic issues like cancer and reproductive problems. A brand-new study adds even more evidence to the growing body of research.

Published a few weeks ago, this latest study found an association between living close to a golf course and the odds of developing Parkinson’s Disease. People living within 1 to 3 miles of a golf course were found to be at greatest risk.

What is it about living close to a golf course that’s associated with developing Parkinson’s Disease? Is it breathing in airborne chemicals? Is it groundwater contamination? Does geology have anything to do with it?

In a brand-new video, I answer these important questions. I also address whether or not it’s safe to forage and hunt near golf courses.

I Don’t Think This Poet Is Wrong

“Our relation to the natural world takes place in a place.”

The American poet Gary Snyder wrote those words. I don’t think he’s wrong.

Every time we harvest a wild mushroom, we do so in a place. Every time we add a new bird to our life list, we do so in a place. Every time we gather spring water and admire a wooded valley, we do so in a place.

Alvars, bogs, fens, forests, marshes, prairies, savannas, and swamps are all places where life abounds. When we refer to these places specifically as “ecosystems,” a few interesting things happen: We see important connections, we see intricate relationships, and we see where humans fit into the story.

If you want to strengthen your connection to nature by learning these fascinating ecosystems, consider enrolling in Exploring Wild Ecosystems. This is my newest online course designed to improve your ecological literacy.

Today is the last day of the sale.

If This Isn’t Good Medicine, I Don’t Know What Is

To find good medicine, look in a forest. In a forest, you’ll encounter plants that have the ability to heal human ailments.

Many years ago, I learned about the medicinal properties of a particular woody plant. This woody plant, when applied to my face as an extract, improved my poor complexion.

Over the years, I’ve been able to maintain a decent complexion thanks to this plant (and thanks to significant lifestyle changes). While I no longer rely on this plant to heal my physical ailment, I do rely on it to address an existential problem.

Plaguing the human species, this problem can be solved if we know where to look.

To learn more about this plant and its ability to offer good medicine, check out the brand-new video.

I’d also like to mention that I’ll be part of the Wild Ones Western PA Chapter’s annual symposium on March 26, where I’ll be joining a panel discussion focused on strengthening communities and native habitats.
