MLRA notes
Major Land Resource Area (MLRA): 144A–New England and Eastern New York Upland, Southern Part
MLRA 144A: New England and Eastern New York Upland, Southern Part. The eastern half of the eastern part of this MLRA is in the Seaboard Lowland Section of the New England Province of the Appalachian Highlands. The western half of the eastern part and the southeastern half of the western part are in the New England Upland Section of the same province and division. The northwestern half of the western part is in the Hudson Valley Section of the Valley and Ridge Province of the Appalachian Highlands. This MLRA is a very scenic area of rolling to hilly uplands that are broken by many gently sloping to level valleys that terminate in coastal lowlands. Elevation ranges from sea level to 1,000 feet (0 to 305 meters) in much of the area, but it is 2,000 feet (610 meters) on some hills. Relief is mostly about 6 to 65 feet (2 to 20 meters) in the valleys and about 80 to 330 feet (25 to 100 meters) in the uplands.
This area has been glaciated and consists almost entirely of till hills, drumlins, and bedrock-controlled uplands with a mantle of till. It is dissected by narrow glacio-fluvial valleys. The southernmost boundary of the area marks the farthest southward extent of Wisconsinian glaciation on the eastern seaboard. The river valleys and coastal plains are filled with glacial lake sediments, marine sediments, and glacial outwash. The bedrock in the eastern half of the area consists primarily of igneous and metamorphic rocks of early Paleozoic age. Granite is the most common igneous rock, and gneiss, schist, and slate are the most common metamorphic rocks. In the parts of the MLRA in eastern and southeastern New York, Devonian- to Pennsylvanian-age sandstone, shale, and limestone are dominant. Carbonate rocks, primarily dolomite and limestone, are the dominant kinds of bedrock in the part of this MLRA in northwestern Connecticut.Classification relationships

The Moist Sandy Outwash ecological site consists of very deep, moderately well drained soils formed in glaciofluvial deposits. They are nearly level to strongly sloping soils on terraces, deltas, and outwash plains. Representative soils are Amostown, Castile, Deerfield, Eldridge, Elnora, Horseneck, Pascack, Pompton, Stafford and Sudbury,. These sites are very similar to the Moist Silty Outwash counterpart, but have fewer ferns and a less diverse understory. The representative plant communities are varied but consist largely of northern red oak (Quercus rubra), and occasional white oak (Quercus alba) or black oak (Quercus velutina),) and red maple (Acer rubrum) with occasional tulip tree (Liriodendrion tulipfera), and occasional pines (pitch pine (Pinus rigida) and white pine (Pinus strobus).

The Koppen-Geiger climate classification of the area in which this MLRA occurs varies between Dfb (Warm-summer humid continental) in the North, and Dfa (Hot-summer humid continental) in the southern portion of the MLRA. Precipitation is usually uniformly distributed throughout the year. Near the coast, however, it is slightly lower in summer. Precipitation is slightly higher in spring and fall in inland areas. Rainfall occurs as high-intensity, convective thunderstorms during the summer. During the winter, most of the precipitation occurs as moderate-intensity storms (northeasters) that produce large amounts of rain or snow. The freeze-free period increases in length to the south.

">Influencing water features
Poorly drained<br />
Water is removed so slowly that the soil is wet at shallow depths periodically during the growing season or remains wet for long periods. Internal free water occurrence is shallow or very shallow and common or persistent. Free water is commonly at or near the surface long enough during the growing season that most mesophytic crops cannot be grown, unless the soil is artificially drained. The soil, however, is not continuously wet directly below plow depth. Free water at shallow depth is common. The water table is commonly the result of low or very low saturated hydraulic conductivity, nearly continuous rainfall, or a combination of these.<br />
<br />
Very poorly drained<br />
Water is removed from the soil so slowly that free water remains at or very near the surface during much of the growing season. Internal free water occurrence is very shallow and persistent or permanent. Unless the soil is artificially drained, most mesophytic crops cannot be grown. The soils are commonly level or depressed and frequently ponded. In areas where rainfall is high or nearly continuous, slope gradients may be greater.Wetland description

[Caveat: The vegetation information contained in this section and is only provisional, based on concepts, not yet validated with field work.*]
The vegetation groupings described in this section are based on the terrestrial ecological system classification and vegetation associations developed by NatureServe (Comer 2003). Terrestrial ecological SYSTEMS are specifically defined as a group of plant community-types called ASSOCIATIONS that tend to [co-]occur within landscapes with similar ecological processes, substrates, and/or environmental gradients. Any given system will typically manifest itself in a landscape at intermediate geographic scales of tens-to-thousands of hectares and will persist for 50 or more years. A vegetation association is a plant community that is much more specific to a given soil, geology, landform, climate, hydrology, and disturbance history. It is the basic unit for vegetation classification and recognized by the US National Vegetation Classification (US FDGC 2008). Each association will be named by the diagnostic and often dominant species that occupy the different height strata (tree, sapling, shrub, and herb). Within the NatureServe Explorer database (NatureServe, 2015), ecological systems are numbered by a Community Ecological System Code (CES) and individual vegetation associations are assigned an identification number called a Community Element Global Code (CEGL).
Additional and more localized vegetation information is provided by the State Natural Heritage Programs of Connecticut (Metzler and Barrett 2001), Massachusetts (Swain and Kearsley 2001), New Hampshire (Sperduto and Nichols, 2011), New York (Edinger et al., 2014), and Rhode Island (Enser and Lungren, 2006).
The Moist Sandy Outwash ecological site is characteristic of the Northern Atlantic Coastal Plain Hardwood Forest system (CES203.475) and North-Central Appalachian Acidic Swamp system (CES202.604). The representative plant communities are varied but consist largely of oaks northern red oak (Quercus rubra), and occasionally white oak (Quercus alba)) and red maple (Acer rubrum) with occasional tulip tree (Liriodendrion tulipfera), and occasional pines (pitch pine (Pinus rigida) and white pine (Pinus strobus). Natural disturbances include climate extremes such as, excessive droughts, or storm activity ranging from windthrows to downbursts to ice-storms. Atmospheric deposition may effect trees at high elevations. Wildfires do happen but are largely suppressed. Other agents-of-change include land conversions and fragmentation by agricultural, development and logging. Invasive plants include tree-of-heaven (Ailanthus altissima), European buckthorn (Rhamnus cathartica), multiflora rose (Rosa multiflora) and Japanese barberry (Berberis thunbergii).
[*Caveat] The information presented is representative of very complex vegetation communities. Key indicator plants and ecological processes are described to help inform land management decisions. Plant communities will differ across the MLRA because of the naturally occurring variability in weather, soils, and geography. The reference plant community is not necessarily the management goal. The drafts of species lists are merely representative and are not botanical descriptions of all species occurring, or potentially occurring, on this site. They are not intended to cover every situation or the full range of conditions, species, and responses for the site.State and transition model

Translated Name: Northern Red Oak - Yellow Birch / Cinnamon Fern Forest
Common Name: Upland/Wetland Transitional Forest (CEGL006000)
The tree canopy is nearly closed, with tree height reflecting moisture availability. Dominant species include red maple (Acer rubrum), yellow birch (Betula alleghaniensis), northern red oak (Quercus rubra), and black oak (Quercus velutina). Occasionally white oak (Quercus alba), pin oak (Quercus palustris), swamp white oak (Quercus bicolor), and eastern hemlock (Tsuga canadensis) as well as tuliptree (Liriodendron tulipifera) may occur. The shrub layer includes witch hazel (Hamamelis virginiana), highbush blueberry (Vaccinium corymbosum), sweet pepperbush (Clethra alnifolia), mountain laurel (Kalmia latifolia), and northern spicebush (Lindera benzoin). Herb layer is often dominated by ferns cinnamon fern (Osmunda cinnamomea), interrupted fern (Osmunda claytoniana), New York fern (Thelypteris noveboracensis), Jack-in-the-pulpit (Arisaema triphyllum), and sessile-leaved bellwort (Uvularia sessilifolia). Jewelweed (Impatiens capensis), American false hellebore (Veratrum viride), and skunk cabbage (Symplocarpus foetidus) may also occur where this vegetation grades into a wetland forest.

Rangeland health reference sheet
Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant community cannot be used to identify the ecological site.
