Pennsylvania Master Naturalist Understanding Ecoregions “In every outthrust headland, in every curving beach, in every grain of sand there is the story of the earth.” --Rachel Carson
8
Ecoregions bring order to something complex – the natural landscape.

Classifying Ecoregions

Pennsylvania Level II Ecoregions
12
Pennsylvania Level III Ecoregions
13
Southeastern and Coastal Plains
14
Northern Piedmont Piedmont Upland, Piedmont Limestone/ Dolomite Lowland, Triassic Lowland
15
Northern Piedmont Piedmont Uplands Rounded hills, low ridges, high relief and narrow valleys. Substantially higher relief than neighboring ecoregions. Folded and faulted paleozoic and precambrian metamorphic rock. Deep Ultisols and Inceptisols are common soils. Chrome soils from serpentinite also occur. The Chrome soils support eastern serpentine barrens (Chester, Delaware, and Lancaster counties)
16
Northern Piedmont Piedmont Limestone/Dolomite Lowlands Nearly level, undulating terrain consisting of sink holes, caverns, and disappearing streams. Ordovician limestone predominates, dolomite and shale also occur. Soils are derived largely from carbonate rock and are very fertile. Soils support a natural vegetation of Appalachian Oak Forest (white and red oak), which has been almost entirely replaced by general farming.
17
Northern Piedmont Triassic Lowlands Wide undulating ridges, broad valleys, limited local relief. Underlain by sedimentary rock. Soils are derived triassic sandstone, shale, siltstone, and argillite. Soils support a natural vegetation of Appalachian Oak forest (dominated by red and white oaks). Supports a mosaic of dairy farms, houses, and woodland.

Middle Atlantic Coastal Plain: Delaware River Terraces & Uplands
20
Low, nearly level terraces. Ocean modified climate. Saline marsh deposits dominate; alluvial and estuarine sand and silt also widespread. Underlain by unconsolidated and easily eroded Quaternary gravels, sands and silts.
