I am often asked questions about how to manage our urban forest. That is, your back yard shade tree. These trees have to survive in a very demanding environment very different from our natural forested environments. My first comment to most is to consult with a certified arborist through the International Society of Arborculture (ISA). These folks have to pass a rigorous exam and are required to take continuing education courses in order to maintain certification.
Second I often refer folks to one of a few very good web sites. I thought I might share a few of these with my readers.
The first is a site entitled "Trees Are Good." It is sponsored by the ISA. The most important section on this site is the "Tree Care Information" link found across the top of the page. This page provides you with brief, up to date information on everything from selection to pruning and mulching. I often refer folks to these fact sheets. They are a wealth of information.
The second site was referred to me by a homeowner in the area who was interested in planting a screen of very fast growing trees. In his search he came across this site. I will caution you however, the fastest growing tree is not always the best choice to plant. The site does provide some great selections though.
Lastly, is a site called "Pennsylvania Trees." This site provides a wealth of information for the PA tree owner. It was put together by a number of professional entities including Penn State, DCNR Bureau of Forestry, the local ISA Chapter, USDA Forest Service, and others.
I hope you find these web sites useful in answering some of your urban forestry questions. Penn State Cooperative Extension also provides a wide array of publications on managing trees in urban settings, everything from selection and planting to pests and fertilizing. Contact your county office for a complete list.

"What is a podcast?" Simply put, a podcast is similar to a radio broadcast. It comes from the combination of the word iPod and broadcasting. However, a podcast can be played on any computer or device that supports the MP3 format, including iPods. People can subscribe to receive topic specific podcasts via Really Simple Syndication (RSS) channel. This is similar to a magazine subscription except that it is a broadcast instead of print.
Dr. Hansen’s first podcasts are available at the iTunes store. To access them you need to have the free iTunes download on your computer and then visit iTunesU at The Pennsylvania State University. On the iTunesU site scroll down to The College of Agricultural Sciences, click there and find NE Pennsylvania Forests. Podcasts currently available are "Selling Timber" and "Emerald Ash Borer." While on the site, subscribe to NE Pennsylvania Forests and listen to future podcasts as they are uploaded. Future podcasts will cover topics on the care and management of woodlands, especially relating to Pennsylvania.
While you are on your computer, visit the Bradford County Extension website at http://bradford.extension.psu.edu. On that site, navigate to the natural resources link and then the forestry resources link. There scroll down to the podcast site and click on the Northeast PA Forests link. Visit the site often to try it out.
After listening to the podcast Bob welcomes your feedback and ideas for future topics. If you have suggestions, email Bob at firstname.lastname@example.org. New 'casts will be posted on a regular basis. Listening to these podcasts is a new and simple way to get a daily dose of forestry. Try it out.

Residents of Adams, Bedford, Berks, Blair, Centre, Clearfield, Clinton, Cumberland, Franklin, Huntingdon, Lackawanna, Lehigh, Luzerne, Lycoming, Mifflin, Montour, Northumberland, Perry, Potter, Schuylkill, Snyder, Tioga, Union, and York Counties soon will see an emergence of periodical cicadas, commonly but mistakenly called 17-year locusts. "These insects are harmless to people, but they can damage shade trees, fruit trees or high-value ornamentals," says Penn State Extension entomologist Gregory Hoover.
Damage caused by periodical cicadas occurs during egg-laying. Using the blades of a saw-like device on her abdomen, a female will cut several small pockets in the bark of a twig before depositing 400 to 600 eggs. This process can cause small limbs or seedlings to wilt and may provide an opening for disease. Adults live only a few weeks, but the twig injury they cause may be apparent for several years.
Adult cicadas are clumsy flyers, often colliding with objects in flight. Males begin their constant singing shortly after they emerge, but the females are silent. When heard from a distance, the cicadas' chorus is a whirring monotone, sometimes described as eerie-sounding. On rare occasions when an adult eats, it sucks fluid from small twigs but does not feed on leaves. Ten days following emergence, mating takes place.
Adults live up to four weeks above ground. Six to seven weeks after the eggs are laid, the nymphs hatch and drop to the ground. There, they enter the soil, not to see the light of day for 17 years.
