General information

Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.

MLRA notes

Major Land Resource Area (MLRA): 149B–Long Island-Cape Cod Coastal Lowland

149B—Long Island-Cape Cod Coastal Lowland

This area is in the Embayed Section of the Coastal Plain Province of the Atlantic Plain. It is part of the partially submerged coastal plain of New England. It is mostly an area of nearly level to rolling plains, but it has some steeper hills (glacial moraines). Ridges border the lower plains. The Peconic and Carmans Rivers are on the eastern end of Long Island. The parts of this area in Massachusetts and Rhode Island have no major rivers. This entire area is made up of deep, unconsolidated glacial outwash deposits of sand and gravel. A thin mantle of glacial till covers most of the surface. Some moraines form ridges and higher hills in this area of generally low relief. Sand dunes and tidal marshes are extensive along the coastline.

Ecological site concept

The site consists of very deep, well drained, coarse-loamy soils formed in dense glacial till. They are gently sloping to strongly sloping soils on or near terminal moraines. Representative soils are Nantucket and Montauk loam phase.
The reference plant community is considered to be an Mixed oak-hardwood forest with occsional pines. Oaks were found to be dominant on terminal moraines within Cape Cod while pitch pine dominated sandy outwash sites (Parshall et al. 2003). Common oaks include black oak, scarlet oak, white, and scrub oak. Pitch pine is subdominant with lesser amounts of beech and hickories. Common shrubs include lowbush blueberry and black huckleberry. Post settlement clearing of forests and an increase in fire has led to a dominance of pitch pine over oaks on terminal moraines within Cape Cod (Parshall et al. 2003). In the absence of severe or frequent fire, oaks replaces pitch pine while other hardwoods such as beech and hickories become a larger component of the forests on more mesic sites.(Parshall et al. 2003).

Climatic features

Coastal regions' climate generally considered maritime, experiences a more moderate climate than inland, i.e., cooler summers and warmer winters and delayed onset of spring. However, coastal regions do experience the brunt of extreme weather such as nor'easters and tropical storms, e.g., hurricanes

Ecological dynamics

[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 (associations) that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients. They are intended to provide a classification unit that is readily mappable, often from terrain and remote imagery, and readily identifiable by conservation and resource managers in the field. A 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; USNVC 2017). Each association will be named by the diagnostic and often dominant species that occupy the different height strata (tree, shrub, and herb). Within the NatureServe Explorer database, 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).

[*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.

This ecological site, set in well-drained dense till ecological site, supports reference plant communities of mixed hardwoods, such as oaks (Quercus, spp.), hickories (Carya spp.), American beech (Fagus gradifolia), and occasionally tuliptree (Liriodendron tulipifera) and occasional pines (Pinus spp.). Oaks were found to be dominant on terminal moraines within Cape Cod while pines dominated sandy outwash sites (Parshall et al. 2003). These plant communities coincide with Northern Atlantic Coastal Plain Dry Oak-Hardwood Forest system(CES203.475), and Northern Atlantic Coastal Plain Heathland and Grassland (CES203.895). The prevailing ecological processes are related to coastal influences, such as a coastal climate and storms, and if within close proximity to the coast, maritime effects of wind exposure, salt spray, and sand movement. Fire can be an influence. Threats include development and fragmentation, fire-suppresion, off road vehicles, and invasive plants such as, but not limited to, black locust (Robinia pseudoacacia), tree-of-heaven (Ailanthus altissima), autumn olive (Elaeagnus umbellata), white poplar (Populus alba), multiflora rose (Rosa multiflora), Honeysuckles, (Lonicera spp.), oriental bittersweet (Celatrus orbiculatus), japanese knotweed (Polygonum cuspidatum) wineberry (Rubus phoenicolasius), and Asiatic tearthumb (Polygonum perfoliatum).

Site Development and Testing Plan
Future work is needed, as described in a project plan, to validate the information presented in this provisional ecological site description. Future work includes field sampling, data collection and analysis by qualified vegetation ecologists and soil scientists. As warranted, annual reviews of the project plan can be conducted by the Ecological Site Technical Team. A final field review, peer review, quality control, and quality assurance reviews of the ESD are necessary to approve a final document.

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.
