Tour university’s ‘tree museum’

Part of the free Get Outdoors Poconos series

Sunday, September 23, 2018 10:00 AM - 11:30 AM

Brodhead Watershed Association

The cool green shade of trees on East Stroudsburg University’s campus is a blessing on a steamy day. On Sept. 23, the Brodhead Watershed Association and ESU assistant professor Emily Rollinson will lead a walk to explore all the arboretum offers.

An arboretum is a botanical garden devoted to trees — a sort of living museum. Over the years, many kinds of trees have been planted and grown to maturity at ESU, both native and exotically non-native.

There is an import from Europe, an enormous copper beech. Then a fluttery crown of a gingko, an import from Asia, whose pedigree reaches back 270 million years in the fossil record. Next comes a small native shadblow, one of the first spring bloomers to brighten our forests in eastern Pennsylvania.

Rollinson, an assistant professor of biology, will show participants the finer points of the arboretum. Participants will also get a printed guide, “Arboretum Guide: The Trees of the ESU Campus,” which maps where trees of interest are located throughout the campus, identifies them and highlights interesting facts and characteristics of each one.

One large tree can lift as much as 100 gallons of water a day out of the ground, extract the nutrients it needs and then “breathe” the rest into the air. Climate scientists have found that as trees cycle water out of the ground and into the air, they actually cool the earth’s surface — gorgeous, green, natural air conditioners.

Come join this urban hike and see what walking among trees can do for you!

Join hike leader Carol Hillestad for this easy hike of about 1.5 miles. Dr. Emily Rollinson will join the hike and share information about the arboretum. Registered hikers will receive a copy of the “Arboretum Guide.”
