Conservation and Management
Inland calcareous lake shores are threatened by development (e.g., residential, agricultural, industrial) in the surrounding landscape. Structures built along the shoreline are a particular threat to this community (e.g., riprap, boat launches). Other threats include habitat alteration (e.g., instream gravel mining, road crossings, logging in adjacent floodplain), and relatively minor recreational overuse (e.g., boating, ATVs, trampling by visitors, fishing, trash dumping). Threats to adjacent lakes may apply to the inland calcareous lake shores (e.g., pollution, nutrient loading, sedimentation, impoundments and flooding, water release for rafting). Several inland calcareous lake shores are threatened by invasive species.
Conservation Strategies and Management Practices
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 lake shore. 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 lake shore and surrounding landscape. For example, roads and trails should be routed around lake shores, and ideally not pass through the buffer area. If the lake shore must be crossed, then bridges and boardwalks are preferred over filling. Restore sites that have been unnaturally disturbed (e.g., remove obsolete impoundments and ditches in order to restore the natural hydrology). Prevent the spread of invasive exotic species into the lake shore through appropriate direct management, and by minimizing potential dispersal corridors, such as roads.
Development and Mitigation Considerations
Where practical, establish and maintain a natural lake shore buffer to filter storm-water, pollution, and nutrient run-off from surrounding uplands and to capture sediments before they reach the lake shore. Avoid habitat alteration along the shoreline and in surrounding landscape. Minimize potential dispersal corridors for exotic species, such as roads and bridges. Maintain or restore the natural flood and ice scour regime.
Survey for occurrences statewide to advance documentation and classification of inland calcareous lake shores. Continue searching for large sites in good condition (A- to AB-ranked).
Research composition of inland calcareous lake shores statewide in order to characterize variations. More data are needed to clearly separate this community from inland non-calcareous lake shore, cobble shore wet meadow, and marl pond shore.
