| 6 | WLP 2670 | RJL2022PA-016 | Acer negundo L. | Pennsylvania, United States | NA | | | 2022 | COLLECTED | 10/21/2022 | Plants growing in woodlands above a small unnamed creek that dumps into the Middle Branch White Clay Creek in Goddard Park, West Grove Pennsylvania, off of Wickerton Road, Chester County. Plants are found regularly but scattered in the understory of the woodlands. | 39.80426000, -75.82609300 | 105 | Plants growing in a mesic, well-drained habitat of deciduous woodlands along streams and above the riparian zone that drains toward a small unnamed creek that feeds into the Middle Branch White Clay Creek. Plants generally grow in part shade to full sun, but perform best and fruit more heavily in full sun where there is abundant access to moisture. The remnant woodlands exist mostly along the steep slopes, wetlands and seeps of seasonal and year-round creeks flowing into the Middle Branch White Clay Creek. The woodlands are bordered by numerous housing developments and land converted to meadows; hence there is significant first order edge that is heavily impacted by invasive plant intrusion. Despite this fact, Acer negundo is highly competitive and competes well.
Soils: The underlying geology of this area is the Glenarm Wissahickon Formation of lower Paleozoic origin and lithologically similar to oligoclase-mica schist of the Wissahickon Formation (PZw), but also includes lenticular amphibolite bodies having ocean-floor basalt chemistry.

The primary soil type in the area of this collection is classified as Glenelg silt loam, 3 to 8 percent slopes. This series consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. Saturated hydraulic conductivity is moderately high in the subsoil and moderately high to high in the substratum. This upper horizon of this soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion.
