Site Description
Abby Road (ABBY) is a terrestrial NEON field site located approximately 30 km (18 mi.) northeast of Vancouver, WA and situated in the western foothills of the Cascade Range in the Yacolt Burn State Forest. The 29.9 km2 (7390 acre) site is a conglomerate of parcels managed by the Washington Department of Natural Resources (WDNR) and is typical of WDNR land in the area. Different parcels have logging years that range from 1940 to 2016, allowing for the opportunity to collect NEON data on a dynamically managed forest landscape. ABBY is located in NEON's Pacific Northwest Domain (D16), which is bounded by the Pacific on the west and Canada on the north. It includes the eastern halves of Washington and Oregon and parts of northern California. The Domain hosts three other field sites: two aquatic and one additional terrestrial.

Geology
Historic volcanic and glacial activity largely defines the geology of ABBY. Basalt and andesite flows dominate the area, with pre-Fraser alpine glacial drift influence near the flux tower.
Vegetation
Douglas fir (Pseudotsuga menziesii) and western hemlock (Tsuga heterophylla) dominate the upper canopy in older stands, with pockets of red alder (Alnus rubra) in mixed forest zones. In recently logged areas, western red cedar (Thuja plicata) grows between the planted Douglas fir. The understory varies with succession; short stature vine maple (Acer cercinatum) is often found in recently logged parcels while salmonberry (Rubus spectabilis) is more common in shrubby habitats. Salal (Gaultheria shallon) and Cascara buckthorn (Frangula purshiana) are found throughout the ABBY site.
Soils
The physical and chemical weathering of igneous rock and volcanic ash produced the majority of soil types present at ABBY, including the Cinebar, Kinney, Larchmount, Olympic, Ferteg, Huss, and Aschoff soil series. Most series have only a minor presence; Cinebar silt loam and Kinney silt loam each make up about a third of the overall soil components across the site. Another minority series is the Yacolt soil series, formed by alpine glacial drift mixed with basalt, pumice and volcanic ash alluvium. Most ABBY soils classify as andisols or andic type soils, owing to a high presence of weathered volcanic glass.
