Gray | New Jersey, United States | NA | | | 2024 | COLLECTED | 11/24/2024 | Mullica Township: Both sides of Duerer Street, approximately 0.37 kilometers southeast of 4th Avenue. | 39.55885000, -74.66442500 | 21 | Shade to almost full sun on compacted seasonally moist to temporarily wet areas of a mixed evergreen and deciduous woodland dominated by Pinus rigida. Vegetation of this area is very much defined by small changes in elevation that go from wet to very dry. Ilex glabra remains abundant throughout, though. Slope: N/A. Aspect: N/A. The underlying geology of this area is the Cohansey Formation of middle Miocene origin and comprised of sand, white to yellow with local gravel and clay. It is sometimes locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where it is interbedded with thin beds of ironstone. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. Maximum thickness in the map area is about 60 meters; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion. (Source: USGS New Jersey Geologic Map Data). The primary soil type in the area of this collection is classified as Mullica Series sandy loam, 0 to 2 percent slopes. These soils are typically coarse-loamy, siliceous, semiactive, and mesic typic humaquepts that are strongly to extremely acidic throughout the profile. The typical solum thickness ranges from 50-150+ cm. These soils are generally considered to be poorly drained. (Source: NRCS Web Soil Survey). | Wild material | | 2169930 | NA 88593 |
