Greiders Run Nature Preserve

About This Preserve
  • 1 Acre
  • Region: Central
  • Coordinates: 40.00033, -76.29172

Ecology and Management

Greiders Run is managed for its habitat being of highest and best use.

Adopted by Martin Stolpe and Bill Ebel, both long-serving Conservancy members, these volunteers manage invasive trees and shrubs and have restored the understory of this preserve with native  flowering trees beneath a towering canopy of predominately tulip polar. This small, semi urban nature preserve serves as a demonstration for landowners with limited space and smaller forested areas. Creative brush piles offer homes for birds and small mammals.


Greiders Run flows directly into Mill Creek which empties into the Conestoga River and ultimately into the Susquehanna River just beneath the Safe Harbor Dam.

Hunting Information
