MLRA notes
Major Land Resource Area (MLRA): 141X–Tug Hill Plateau
MLRA 141 is entirely in New York and makes up about 1,173 square kilometers (3,037 square kilometers). It consists of a relatively small but unique upland that lies just off the eastern end of Lake Ontario and west of the Black River Valley and Adirondack Mountain region. It is essentially a north- and east-facing glaciated cuesta scarp and is underlain by thick Wisconsin till and small areas of outwash. Most of the plateau is woodland, so forestry and recreation are the primary uses, but small isolated dairy operations and hobby farms are located around the perimeter.
The area is bordered on the east by the Black River Valley, on the north by the St. Lawrence Lowland, on the west by the Ontario Lowland, and on the south by the Upper Mohawk Valley. The northern and eastern boundaries of MLRA 141 are distinct where they contact the physiographically dissimilar southwestern part of MLRA 142 (St. Lawrence-Champlain Plain). The western and southern boundaries are also distinct where they contact the physiographically dissimilar MLRA 101 (Ontario-Erie Plain and Finger Lakes Region)
Ecological site concept
This site occurs next to small rivers and streams and includes a complex of soils and landforms associated with floodplains. Poorly-drained banks occur nearest the channel, with broad, somewhat poorly to moderately well-drained floodplains behind. Side channels often carry large amounts of water into the floodplains at high flows, and the lowest areas of the floodplain, including poorly- and very poorly-drained oxbows and depressions, may be ponded at times. Soils are derived from alluvium, are typically silt loams to fine sands in texture, and may have gravel or sand layers from particular flooding events. Poorly-drained soils are often organic over alluvium. Representative soils include: Carbondale, Carlisle, and Rifle.
The variability in microtopography on this site results in a patchy mosaic of plant communities that may include trees, shrubs, and herbs. Diverse grasses and other herbaceous species indicate differences in soil wetness throughout the site due to slight variability in elevation above the water table. This site is subject to flooding and ice scour, which periodically removes woody species, maintaining the herbaceous component of the plant community. Beaver activity can alter reaches of this site by slowing the flow, which results in less flooding and scour. These narrow landforms are nutrient rich with high water-holding capacity, but are too small for extensive cultivation. Much of this site occurs upstream of dams, though altered flow regimes below dams may have significant impact on this site. Further study is needed to better describe the properties and disturbances that define this site concept. There are likely more than one Marsh Wetland ecological sites in this MLRA.
These freshwater emergent and/or submergent marshes are dominated by herbaceous vegetation. They are common throughout the northeastern United States and adjacent Canadian provinces. Freshwater marshes occur in closed or open basins that are generally flat and shallow. They are associated with lakes, ponds, slow-moving streams, and/or impoundments or ditches. The herbaceous vegetation does not persist through the winter. Scattered shrubs are often present and usually total less than 25% cover. Trees are generally absent and, if present, are scattered. The substrate is typically muck over mineral soil.

Climatic features
Throughout the year precipitation is evenly distributed around most of this area with slightly less rainfall occurring around the lower margins of the plateau. Rainfall occurs as high-intensity, convective thunderstorms during the summer. Lake-effect snowfall is heavy from late autumn to early spring with the summit of the plateau having the lowest temperatures and the shortest freeze-free periods.
Climate stations Watertown and Old Forge are adjacent to the MLRA and were used to tabulate additional representative climate data.

Influencing water features
This ecological site is associated with lakes, ponds, slow-moving streams, and/or impoundments or ditches. Due to its low-lying position, this site is susceptible to altered hydrology from beaver dams and man-made structures (e.g. roads). Increased ponding depth and duration results in a ponded phase dominated by emergent vegetation such as cattails. As ponding depth and duration returns to the natural regime due to dam/road removal (or over long periods of time the infilling of pond with sediment and debris) this site will transition through many short-lived marsh communities before eventually returning to dominance by those of the reference community.

Ecological dynamics
[Caveat: The vegetation information contained in this section and is only provisional, based on concepts, and future projects support validation through 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) and localized associations provided by the New York Natural Heritage Program (Edinger et al. 2014).
This site is dominated by diverse graminoid, herb, and shrub species. Shrubs such as speckled alder tend to dominate the higher perimeter and mounds within the marsh site, while diverse sedges, bulrushes, grasses, and forbs dominate the wetter areas. Relatively small changes in soil wetness may alter the distribution of these species within the site, and further study is required to distinguish the relationship between hydrology and vegetation on this site.

Community 1.1
Shallow Emergent Marsh
Shallow emergent marshes typically occur in lake basins and along streams often intergrading with deep emergent marshes, shrub swamps, and sedge meadows, and they may occur together in a complex mosaic in a large wetland. This site occurs on mineral soil or deep muck soils, that are typically permanently saturated and seasonally flooded. Water depths may range from 15 cm to 1 m (6 in to 3.3 ft) during flood stages, but the water level usually drops by mid to late summer and the substrate is exposed during an average year. Shallow emergent marshes are common and variable, and may be dominated by a mixture of herbaceous vegetation or a single species. Shrubs may be scattered throughout marshes, though areas with greater than 50% shrub cover are classified as shrub swamps. The hydroperiod of these sites may determine species composition, with species dependent on differing hydrologic states (permanently saturated, seasonally flooded, or temporarily saturated). (Edinger et al. 2014)
Resilience management. New York Natural Heritage Program State Rank: S5-Demonstrably secure in New York State. Species composition may be strongly influenced by annual and seasonal water levels. These sites may be found on found in agricultural or cleared land that may present issues related to agricultural runoff (pesticide, petroleum, waste, etc.) (Edinger et al. 2014)

Community 1.2
Marsh Headwater Stream
The aquatic community of a small, marshy perennial brook with a very low gradient, slow flow rate, and cool to warm water that flows through a marsh, fen, or swamp where a stream system originates. Most of the erosion is primarily lateral, and deposition can be substantial. The substrate is typically gravel or sand, but some examples or segments may be dominated by silt, muck, peat, marl deposits or woody or leafy debris. These streams may have high turbidity and be somewhat poorly oxygenated and can vary in alkalinity and color. Sparse emergent marshes, floating aquatic beds, submerged aquatic beds, and mussel beds are typically present in this broadly defined community. Four to seven ecoregional variants of marsh headwater stream are suspected to differ in dominant and characteristic vascular plants, fishes, bryophytes, invertebrates, and algae as well as water chemistry, water temperature, underlying substrate type, and surrounding forest type. Major watershed may be a secondary factor in distinguishing streams lower in a drainage basin. (Edinger et al. 2014)
Resilience management. New York Natural Heritage Program State Rank: S4-Apparently secure in New York State. Stream bank erosion can be substantial and deposit excessive sediment and nutrients into these areas. Depending on the surrounding development, this system may experience watershed instability from agricultural runoff and debris during period of heavy precipitation and flooding. More research and data is needed to distinguish characteristic ecological properties, potential conservation issues, and to further define marsh headwater streams within this MLRA.

Sedge Meadow
a wet meadow community that has organic soils (muck or fibrous peat). Soils are permanently saturated and seasonally flooded; there is usually little peat accumulation in the substrate and usually underlain by deep muck. Sparse shrubs may be present and the dominant herbaceous vegetation must be members of the sedge family (Cyperaceae), typically of the genus Carex. Sedge meadows typically occur along streams and near the inlets and outlets of lakes and ponds; they also occur in lake basins as a zone near the upland edge of a shallow emergent marsh. A sedge meadow does not typically form a floating mat, instead it is covered with water during flooding. When water levels are low, there is little or no open water. (Edinger et al. 2014)

Shrub Swamp
This systems is generally an inland wetland dominated by tall shrubs that occurs along the shore of a lake or river, in a wet depression or valley not associated with lakes, or as a transition zone between a marsh, fen, or bog and a swamp or upland community. The substrate is usually mineral soil or muck. A few examples may have a shallow layer of sphagnous peat. Shrub swamps are common and variable, and may be dominated by a mixture of herbaceous vegetation or a single species. The hydroperiod of these sites may determine species composition, with species dependent on differing hydrologic states (permanently saturated, seasonally flooded, or temporarily saturated).

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.

Indicators
-
Number and extent of rills:
-
Presence of water flow patterns:
-
Number and height of erosional pedestals or terracettes:
-
Bare ground from Ecological Site Description or other studies (rock, litter, lichen, moss, plant canopy are not bare ground):
-
Number of gullies and erosion associated with gullies:
-
Extent of wind scoured, blowouts and/or depositional areas:
-
Amount of litter movement (describe size and distance expected to travel):
-
Soil surface (top few mm) resistance to erosion (stability values are averages - most sites will show a range of values):
-
Soil surface structure and SOM content (include type of structure and A-horizon color and thickness):
-
Effect of community phase composition (relative proportion of different functional groups) and spatial distribution on infiltration and runoff:
-
Presence and thickness of compaction layer (usually none; describe soil profile features which may be mistaken for compaction on this site):
-
Functional/Structural Groups (list in order of descending dominance by above-ground annual-production or live foliar cover using symbols: >>, >, = to indicate much greater than, greater than, and equal to):
Dominant:
Sub-dominant:
Other:
Additional:
-
Amount of plant mortality and decadence (include which functional groups are expected to show mortality or decadence):
-
Average percent litter cover (%) and depth ( in):
-
Expected annual annual-production (this is TOTAL above-ground annual-production, not just forage annual-production):
-
Potential invasive (including noxious) species (native and non-native). List species which BOTH characterize degraded states and have the potential to become a dominant or co-dominant species on the ecological site if their future establishment and growth is not actively controlled by management interventions. Species that become dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the ecological site:
-
Perennial plant reproductive capability:
