biodiversity – Paths I Walk

I’m excited to announce that I’ll be leading a series of forest ecology outings, and I’d love for you to join me!

On August 30 and 31, 2025, I will be leading two Summer Forest Ecology Outings at McConnells Mill State Park in Pennsylvania.

Designated a National Natural Landmark for its outstanding features, McConnells Mill 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.

On October 11 and 12, 2025, I will be leading two Old-Growth Forest Ecology Outings at Cook Forest State Park.

Located in northwestern Pennsylvania, Cook Forest is home to one of the last remaining old-growth forests in the entire region, with 11 old-growth areas spanning over 2,300 acres. One of the areas within the park, the Forest Cathedral, contains arguably the finest concentration of old-growth trees in the northeastern United States.

During these outings, 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 and old-growth forests, participants will learn tree identification, mushroom ecology and identification, the role of fire as an ecological agent, ways to interpret forest history, and much more.

These outings are great opportunities to learn, explore, and connect with nature in spectacular settings. They’re also great opportunities to meet wonderful people.

Please note: Each outing is a single-day event. 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!

Greetings,

I am excited to announce that my newest online course, Exploring Wild Ecosystems, is now open for enrollment!

You can register here.

This course is designed to improve your ecological knowledge by introducing you to fascinating ecosystems — including alvars, barrens, bogs, dunes, fens, glades, savannas, vernal pools, and others!

Learning to recognize ecosystems is an essential step toward understanding how nature works. When we pay attention to the bigger picture, we see beyond individual components. We see connections, we see relationships, and we see where humans fit into the story.

If you want to develop ecological literacy; if you want to be able to read landscapes more effectively; if you want to see how all the components within nature are connected, consider enrolling in Exploring Wild Ecosystems today.

Please note that Exploring Wild Ecosystems is open for one week only — from today until Monday, September 30. After that, registration will be closed. Upon registration, you can immediately access all course content and view the lessons at your own pace.

To learn more about the course, check out this video which gives you an overview of what you can expect.
