Summer Bugs

Insects readily make their presence known at two points during the year - the spring when the aquatic insects emerge to mate, and summer when the more terrestrial bugs set out to do the same. The most noticeable of these warm weather wonders are either visually interesting, like the fireflies, butterflies, and moths or produce a cacophonous chorus like the katydids, crickets, and cicadas. Summer wouldn’t be summer without the regular emergence of fireflies. Easily the most recognized bioluminescent set of species, fireflies’ characteristic green strobe illuminates the night from July to September. The light is a chemical reaction that, unlike most of the ways we can produce artificial light,

Old Growth Trees

Around 8 billion trees cover Pennsylvania’s 16 million acres, yet just over one half of one percent of this area contains trees predating the 20th century. Most of our trees are just nearing their hundredth birthday, which is not nearly as old as the trees standing there before them. These younger, first or early second-generation growth trees have a long way to go before they will resemble the old growth forests of yore. Old growth forests, in Pennsylvania specifically, are usually dominated by large hemlocks or dense stands of pines. These trees readily reach into their quadricentennials and become dominant landscape features whether standing alone or as part of continuous stands. Importan

Lovely Lakes

Pennsylvania is a well-drained state. We have a tremendous quantity of streams and waterways, both above and below ground, that contain and move an enormous quantity of water. With so much moving water, we have very few natural lake systems. We simply don’t have the right conditions throughout most of the state to afford water the luxury to just sit there. Therefore, most of Pennsylvania’s lakes are manmade and engineered to act as a reservoir or for flood control, such as Raystown Lake. Manmade lakes often require dredging or other active control methods to ensure the lake remains a lake and does not transition into other forms of wetlands. Periodically they can even be completely drained f
