Floodplain Forest

This layer delineates both ancient and recently reforested non-tidal, non-swamp floodplain forests of Columbia County, NY. The features identified as ancient include all the areas that were forests in the 1940s (according to B&W aerial photographs available as paper copies at the Columbia County Soil and Water Conservation District, digitized and geo-referrenced by the Hawthorne Valley Farmscape Ecology Program) as well as in 2004 (according to the ortho-photo), located on non-tidal alluvial soils (classified as Ln, Lo, Om, Ce and Fn by the Columbia County Soil Survey of 1989), and did not clearly carry the signature of swamp forest on the aerial photos. The features identified as recently reforested include all the areas that were forested on the 2004 ortophotos, located on non-tidal alluvial soils (classified as Ln, Om, Ce, and Fn by the Columbia County Soil Survey, 1989), did not clearly carry the signature of swamp forest in the aerial photos, and were not forested in the 1940s (according to B&W aerial photos available as paper copies at the Columbia County Soil and Water Conservation District, digitized and geo-referrenced by the Hawthorne Valley Farmscape Ecology Program). https://www.hvfarmscape.org
