Slope: 20-50%. Aspect: Northwest. The underlying geology of this area is of Devonian origin and characterized as the Duncannon Member of Catskill Formation. It is characterized by grayish-red sandstone, siltstone, and mudstone in fining-upward cycles; conglomerate occurs at base of some cycles. The sandstones which comprise the Duncannon Member are fine to very coarse grained and grayish red to grayish red-purple in color. The Duncannon Member is known to be crossbedded to planar bedded in beds anywhere from 3 to 9 meters thick. Conglomerates have been spotted at the base of the Duncannon Member. The Duncannon Member is poorly exposed in most areas except along the Lehigh River. The conglomerate portion of this member has been known to form ridges and ledges with thicknesses approaching 228 meters. (Source: USGS Pennsylvania Geologic Map Data). The primary soil type in the collection area is classified as Dystrochrepts, boulder soils. These soils are characterized by coarse-silty loess over residuum weathered from sedimentary rock and located on steep ridges along the upper third of the mountainflank. These soils are comprised of cobbles, stones or boulders (9%), well-drained, and approximately 1 meter or less to lithic bedrock.

| 2 | NA 88664 | RJL2023PA-001 | Viburnum acerifolium L. | Pennsylvania, United States | NA | | | 2023 | COLLECTED | 10/01/2023 | Seed collected from plants growing along a two-mile stretch of Harmonyville Road on the woodland edge next to the road. [Note: latitude and longitude were collected at the location of the largest seed collection.] | 40.18482200, -75.78145100 | 158 | Plants were growing in well-drained and rocky mesic-dry woodlands from part shade along the road edge to full shade in the understory of the woodlands. Slope: 2-10%. Aspect: Variable. The underlying geology of this area is of Triassic origin and characterized as the Stockton Formation. It is characterized by light-gray to buff, coarse-grained, arkosic sandstone; includes reddish-brown to grayish-purple sandstone, siltstone, and mudstone. (Source: USGS Pennsylvania Geologic Map Data.) The primary soil type in the area of this collection is classified as Edgemont Channery Sandy Loam Series (8 to 25 percent slopes), extremely stony. The Edgemont Series consists of deep and very deep, well drained soils formed in the weathered residuum of quartzitic rocks. They have moderately high to high saturated hydraulic conductivity. Slopes range from 0 to 70 percent. Solum thickness ranges from 50 to 10 cm. Depth to bedrock ranges from about 1.5 to 2.2 meters. Kaolinite is the dominant mineral in the clay fraction with detectable amounts of illite, vermiculite, montmorillonite, chlorite and interstratified clays. Gravel, channers, and stone size fragments of quartzite and quartz are present throughout the profile. Rock fragments range from 5 to 40 percent in the horizons of the solum and from 10 to 90 percent in the C horizon. Reaction ranges from extremely acid to strongly acid throughout.

| 3 | 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.
