Mammals
Mammals fill many roles in our ecosystems and have adapted to fill a variety of niches where they can truly thrive. While some of these wide-ranging furry friends can be found throughout the state, some of them are more reclusive and can only be found in specific habitats. Learn about all the cool ways mammals contribute to our ecology.
Old Growth Trees
There are around 8,000,000,000 trees in Pennsylvania covering over 16,000,000 acres, but only .06% of that contain trees predating the 20th century. Either through early colonization or the later boom-and-bust cycles much of the old-growth forests no longer remain, but we have pockets of theses ancient trees right here in our backyard. Explore some of these sylvan sanctuaries and discover what Pennsylvania was like before people.
Summer Birds
The spring and fall bring the greatest diversity of birds to our region, but what about all the ones that call this place home? Dive into a new understanding of our summer avian residents and learn about some of our friendly flying friends. We will explore species that have adapted to cohabitate with humans and secretive forest dwelling birds.
Historic Land Uses
Take a trip back to the early days of human exploration of central Pennsylvania. From the earliest inhabitants to the rapid progression of colonial expansion land use in our community has changed drastically. Follow along as we dive into our unique cultural history and what these important events mean for us today.
Geologic Formations
We have an unusual geologic history in Pennsylvania, our rocks are upside-down! All of our young rocks make up the valley floors while the older formations are what make up the higher ridges. The same ridges that define our region also helped shape the socio-economic development of our communities. Take some time to explore why rocks rock!
Waterways
Pennsylvania has over 80,000 miles of streams and waterways, and we have the highest stream density of any state! We are indeed a well drained land, and you can scarce find a place to throw a rock that won’t hit a stream. Find out more about a water heritage and the important factors that have come together to make our home so replete with waterways.
Invasive Species
Invasive species are often introduced into an environment and can cause severe harm to those already present. Invasive often have an advantage over their competitors that make them more successful while providing less to the ecosystem than the ones they would be replacing. Learn about the various types of invasive plants, how to identify them, and management strategies to keep them from spreading out of control.
Native Wildflowers
Spring time is synonymous with flowers. From rue anemone to trillium and columbine to jack-in-the-pulpit, a wide variety starts to bloom in the first weeks of May. Many of these early-blooming species can be found on many trails throughout our region. It is often worth visiting a new trail every week to see what new blooms have opened and what others have started to go to seed.
Spring Bugs
Not all bugs are bad! Many of the springtime hatches form an essential part of the lifecycle of everything from fish to birds. Learn about the aquatic lifestyle of some of the most prevalent spring bugs. We will dive in and take a closer look at mayflies, stoneflies, dragonflies, and craneflies.
