Did you know?
A characteristic species found in deep emergent marshes is wild rice (Zizania aquatica and Z. palustris). In addition to providing habitat and food for marsh fish and waterfowl, wild rice has been an important food staple for Native Americans for thousands of years. The ancestral grain of wild rice has even been found in layers of earth dating back 12,000 years! Today, about 23 million pounds of "wild" wild rice varieties as well as "cultivated" wild rice varieties are produced each year around the world, 4 million of which is considered "wild" grown.
|State Ranking Justification||
There are several thousand occurrences 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, or declining slightly elsewhere due to moderate threats that include alteration of the natural hydrology and invasive species.
The number and acreage of deep emergent marshes 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 flooding from impoundments.
The number and acreage of deep emergent marshes in New York has substantially declined (50-75%) from historical numbers likely correlated to the alteration of the natural hydrology and/or direct destruction.
