Major Land Resource Area (MLRA): 144B–New England and Eastern New York Upland, Northern Part
This major land resource area (MLRA) is characterized by plateaus, plains, and mountains. The climate is generally cool and humid with an average annual precipitation of 34 to 62 inches (865 to 1,575 millimeters). The average annual air temperature is typically 40 to 48 degrees F (4 to 9 degrees C). The freeze-free period generally is 130 to 200 days, but it ranges from 110 days in the higher mountains to 240 days in some areas along the Atlantic coast. The soils in this region are dominantly Entisols, Spodosols, and Inceptisols. They commonly have a fragipan. The dominant suborders are Ochrepts, Orthods, Aquepts, Fluvents, and Saprists. The soils in the region dominantly have a frigid soil temperature regime with some cryic areas at higher elevation, a udic soil moisture regime, and mixed mineralogy. Most of the land is forested, and 98 percent is privately owned. Significant amounts of forest products are produced including lumber, pulpwood, Christmas trees, and maple syrup. Principal agricultural crops include forage and grains for dairy cattle, potatoes, apples, and blueberries. Wildlife habitat and recreation are important land uses. Stoniness, steep slopes, and poor drainage limit the use of many of the soils.

Ecological site concept
This site occurs mostly on well- to moderately well-drained loam soils and associated somewhat poorly-drained soils. Bedrock is greater than 20 inches below the mineral soil surface. Soils may be underlain by a densely compacted till layer. This site is commonly found on backslope and footslope positions but may occur on flats or any number of landforms. The vegetation is characterized by northern hardwoods, particularly sugar maple, red maple, yellow birch, red oak and beech, with diverse hardwood associates. Shallower and wetter inclusions in this site typically produce more softwoods, including red spruce, white pine, hemlock, northern white cedar, and balsam fir. This site is likely over-mapped. Perhaps a Silty Slope (mixed wood) concept could reflect consistent, meaningful patterns between vegetation and soil properties. Further field work is required.

Semi-rich Till Slope The Semi-rich Till Slope site has similar soil texture and wetness, but is distinguished by higher soil nutrients derived from calcareous parent material (such as limestone), as evidenced by high soil pH and rich site indicator species. |

F144BY502ME |
Loamy Till Toeslope The Loamy Till Toeslope is somewhat poorly- and poorly-drained, supporting wetter species and more softwoods than the moderately well- and well-drained Loamy Slope site. |
F144BY402ME |
Clay Hills Clay Hills occur on finer-textured soils, usually of glaciomarine or glaciolacustrine origin, and produces more mixedwood stands, while the Loamy Slope site occurs on till soils that are typically coarser in texture and produces more hardwood species. |
F144BY504ME |
Enriched Loamy Cove The Enriched Loamy Cove site has similar soil texture and wetness, but is distinguished by higher soil nutrients which accumulate in protected cove setting and are evidenced by high soil organic matter and rich site indicator species. . |
