PHILADELPHIA (CBS) – Going for a walk on a fall day is a great way to get some fresh air and see some beautiful trees and shrubs you might decide to plant in your own garden. This Sunday, September 15, Bill Astifan, Director of the Haverford College Arboretum, will lead a walk to show off recent work they’ve done along an eroded stream bank by their Nature Trail.

To encourage the spread of native plants and help reduce water runoff and erosion, their efforts entailed everything from bulldozers to a herd of goats to control invasive plants. Yes, I said goats – did you know you can hire goats to eat your invasive weeds? Well you can and you can learn more about that and see how the goats did their job during this “Native Woodland Plants” walk.

It’s free and you don’t need a reservation, you can simply wake up and decide to go. Just put on your walking shoes, dress for the weather and be at the Whitehead Campus Center at Haverford College at 370 Lancaster Avenue, Haverford, PA on Sunday by 1:30 in the afternoon.
