Jewelweed, or touch-me-not, is an herb found in red maple-hardwood swamps. Its name comes from the jewel-like silvery coating on its leaves that is only evident when the leaves are submerged in water. The silvery covering is actually a thin layer of air trapped in microscopic leaf hairs. The plant was nicknamed touch-me-not because of its seed capsules, which split and coil when triggered by the wind or a touch, expelling the seeds and dispersing them up to four feet away.

There are several thousand occurrences statewide. Some documented occurrences have good viability and several 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, or declining slightly elsewhere due to moderate threats that include alteration of the natural hydrology and invasive species.
The number and acreage of red maple-hardwood swamps in New York have probably declined slightly, or remained stable, in recent decades as a result of wetland protection regulations. Since World War II, urbanization has emerged as the predominant force impacting wetlands in most parts of the region (Golet et al. 1993).
The number and acreage of red maple-hardwood swamps in New York have probably declined substantially (about 80%) from historical numbers likely correlated with agricultural and other development. The principal causes of wetland loss in the Northeast prior to mid-1800s include conversion of wetlands to agriculture, the construction of impoundments for hydropower and water supply, and the cutting of swamp timber for lumber, fence posts, and fuel wood (Golet et al. 1993).
