Coastal plain pond shores are threatened by development and its associated run-off (e.g., residential, roads), recreational overuse (e.g., ATVs, hiking trails causing erosion and compaction), and habitat alteration in the adjacent landscape (e.g., logging, pollution, nutrient loading). Alteration to the natural hydrology is also a threat to this community (e.g., flooding, draining, or dredging). Invasive species also threaten this community including the introduction of grass carp to some ponds. Some coastal plain pond shores are too small to be protected by the New York State freshwater wetland regulations. In 2001, the federal Supreme Court ruled that the US Congress did not give authority to the US Army Corps of Engineers (US ACE) under section 404 of the Clean Water Act to regulate the filling of isolated wetlands.

Where practical, establish and maintain a natural wetland buffer to reduce storm-water, pollution, and nutrient run-off, while simultaneously capturing sediments before they reach the wetland. Buffer width should take into account the erodibility of the surrounding soils, slope steepness, and current land use. Wetlands protected under Article 24 are known as New York State "regulated" wetlands. The regulated area includes the wetlands themselves, as well as a protective buffer or "adjacent area" extending 100 feet landward of the wetland boundary (NYS DEC 1995). If possible, minimize the number and size of impervious surfaces in the surrounding landscape. Avoid habitat alteration within the wetland and surrounding landscape. For example, roads and trails should be routed around wetlands, and ideally not pass through the buffer area. If the wetland must be crossed, then bridges and boardwalks are preferred over filling. Restore past impacts, such as removing obsolete impoundments and ditches in order to restore the natural hydrology. Prevent the spread of invasive species into the wetland through appropriate direct management, and by minimizing potential dispersal corridors, such as roads.
| Development and Mitigation Considerations |

When considering road construction and other development activities, minimize actions that will change what the water carries and how water travels to this community, both on the surface and underground. Water traveling over-the-ground as run-off usually carries an abundance of silt, clay, and other particulates during (and often after) a construction project. While still suspended in the water, these particulates make it difficult for aquatic animals to find food; after settling to the bottom of the wetland, these particulates bury small plants and animals and alter the natural functions of the community in many other ways. Thus, road construction and development activities near this community type should strive to minimize particulate-laden run-off into this community. Water traveling on the ground or seeping through the ground also carries dissolved minerals and chemicals. Road salt, for example, is becoming an increasing problem both to natural communities and as a contaminant in household wells. Fertilizers, detergents, and other chemicals that increase the nutrient levels in wetlands cause algae blooms and eventually create an oxygen-depleted environment where few animals can live. Herbicides and pesticides often travel far from where they are applied and have lasting effects on the quality of the natural community. So, road construction and other development activities should strive to consider: 1. how water moves through the ground, 2. the types of dissolved substances these development activities may release, and 3. how to minimize the potential for these dissolved substances to reach this natural community.
This natural community has been well searched for in New York but composition and dynamics are just beginning to be documented and will need addtional work.
Research on these pond systems could include evaluating the effect of secondary disturbances such as fire in the surrounding upland forest on the pond shore, evaluating the effect of elevation in the landscape on the species composition of the pond shore, and determining the variation of the species composition of the plant zones around the pond shore between ponds and pond systems. Other research on these pond shores should involve monitoring of invasive species including exotic fish, monitoring hydrologic changes, and monitoring ponds for eutrophication.
