Wetland Natural Community Descriptions and Management Recommendations Most of the wetlands in Langton Lake Park have formed as a result of the overall increase in the size of Langton Lake from what was originally agriculture surrounding the area. The increases in impervious surface due to the many large parking lots and industrial areas have contributed a significant amount of stormwater to the lake. All of the wetlands, except W1, have connectivity to the lake and receive direct stormwater inputs. Locations of the improvements discussed in the following paragraphs are shown in figure 6.6 Community LL-W1 Seasonally Flooded Basin Qualitative Rank: Medium Area: 0.07 acres This is a small isolated depression surrounded by upland forest on three sides and an upland old field to the north. Reed canary grass is the dominant vegetation. The presence of smartweed and duckweed indicates that this basin holds water during spring or significant rain events.
