In early April, Allderdice students and parents partnered with Nine Mile Run staff Maranda, Jared, and Nathan to plant 16 native trees and shrubs adjacent to the Fern Hollow stream in the restoration area of Nine Mile Run. The entire project was student initiated and organized.
Students Julia Strassburger and Angelo Goldberg reached out to us in March to coordinate a service project as a component for a school project. The students very specifically wanted to contribute to the restoration area with native plants. It was perfect timing as the the Pittsburgh Parks Conservancy and City of Pittsburgh had just completed the removal of 120 small samplings and 7 mature invasive Siberian Elm trees in the restoration area. The result of this removal left a significant ecological gap to be filled.
Siberian elms are native to eastern Asia and were originally introduced into the US in the 1860s for their hardiness and fast growth in moist areas. The species is still sold today as a windbreak tree. The invasive Elms in the restoration area were treated and cut down, but all debris was left behind to provide wildlife habitat.
As for the trees and shrubs, our staff chose wetland specific species. The 16 plants included Blackgum, Red Osier Dogwood, and Red Chokeberry. The plants were generously provided by an Anonymous donor and were sourced entirely from the Tree Pittsburgh Heritage Nursery.
In addition to the trees and shrubs installed by the students, the City of Pittsburgh planted 6 Blue Spruces in this area. The ongoing maintenance of the newly planted trees and shrubs will be assigned to the Urban EcoStewards of that area.
Please remain on the trails when near this area as the newly planted plants are very sensitive to disturbance and their future success is extremely critical. Signs have been installed to indicate this as well.
