Plant a tree, save the planet.

On Sunday, April 28, three Abington-area municipalities will unite with one common mission: to teach the public about why it is necessary to plant trees.

The shade tree commissions of Clarks Summit, Clarks Green and South Abington Township will host an Arbor Day celebration at the Clarks Summit Fire Hall, 321 Bedford St., from 2-5 p.m. This year's celebration will feature a presentation on native plants by Angela Lambert, an interpretative naturalist at Lackawanna State Park.

In preparation for the celebration, the shade tree commissions asked local students to create posters around the theme "Why should I plant a tree?" Prizes will be given to the classroom with the most submissions as well as for individual posters.

Donna Zagrapan, the president of the Clarks Summit Shade Tree Commission, explained why it was important for the schools to get involved with Arbor Day.

"At one of our planning meetings, we were looking for ways to get children involved and we decided on the poster contest for grades one through four across all Abington-area schools, public and private."

The day's events will also include live music by the Invisible Swordsmen, a visit from Smokey the Bear and free seedlings for all attendees. Members of the shade commissions will demonstrate how to plant the trees properly.

Zagrapan explained why Arbor Day should be remembered and celebrated.

"It is an opportunity to remember the importance of trees, they give us welcome shade, they surround us with beauty, they clean our air, they reduce stress and, very importantly to the Abington area, they help to slow down storm water runoff," she said. "Increasing the tree cover in the Abingtons not only helps our local environment but the waterways all the way to the Chesapeake Bay."
