Speckled alder (Alnus incana ssp. rugosa) is a nitrogen-fixing shrub that has been found to increase the concentration of inorganic nitrogen in the surface waters of the Adirondacks. Native Americans used speckled alder in combination with bloodroot, wild plum, and red osier dogwood (Cornus sericea) to make a scarlet dye for porcupine quill embroidery. Inuit people and settlers extracted a dark dye from the bark for tanning and staining hides. The bark was boiled to make medicinal teas for treating rheumatism and was also applied to wounds as a poultice to reducing bleeding and swelling.

There are several thousand shrub swamps statewide. Some documented occurrences have good viability and many are protected on public land or private conservation land. This community has statewide distribution, and includes a few large, high quality examples. The current trend of this community is probably stable for occurrences on public land and private conservation land, or declining slightly elsewhere due to moderate threats that include alteration of the natural hydrology and invasive species.
The number and acreage of shrub swamps in New York have probably remained stable in recent decades as a result of wetland protection regulations. There may be a few cases where this community has increased as a result of abandoned agriculture land.
The number and acreage of shrub swamps in New York have substantially declined (50-75%) from historical numbers likely correlated to the alteration to the natural hydrology and to direct destruction, especially near urban areas.
