Description
The Reference State for the Upper Riparian Terraces ecological site is highly dependent on the fine-scale variability of the hydrologic conditions and the soil characteristic. The soils vary from moderately well drained to excessively drained depending on the elevation above the adjacent water body and the stratification of the soil parent materials. Thus this site is both internally variable and varies from site to site. The reference State is found along undeveloped stretches of shoreline which are becoming increasing rare.

Description
The Developed State includes not only the exact footprint of a particular development, be it road, building, or utility area, but also the adjacent sites affected by the development. This dramatically increases the area of sites that exhibit this state. An estimate of extent depends on the width of the buffer so employed. Cleared land starts re-vegetating naturally with mainly exotic weeds, so it's been recommended to plant a cover crop. However some cover crop plants have turned out to be part of problem.

Description
This state is very common along lakeshores that were developed many years ago and remain unchanged since then. Rustic cabin owners and resort operators often try to maintain a rustic environment on their grounds. Understory vegetation is mostly sparse in this state, especially in the Mature Pines Phase which often has a closed canopy with a shade tolerant shrub-sapling layer of ironwood and sugar maple.
