Nymphaea odorata - Eleocharis robbinsii Aquatic Vegetation
Translated Name: American White Water-lily - Robbins' Spikerush Aquatic Vegetation
Common Name: Coastal Plain Pond
Unique Identifier: CEGL006086
Classification Approach: International Vegetation Classification (IVC)
Summary: This hydromorphic Coastal Plain pond community ranges from southern New England to Maryland. It occurs in standing water in all but exceptionally dry years. The substrate is most often deep muck, but in oligotrophic ponds an organic layer may be absent or much reduced and the vegetation occurs on sand or mucky sand. Characteristic species include Nymphaea odorata, Nymphoides cordata, and Eleocharis robbinsii, with frequent associates including Scleria reticularis, Gratiola aurea, Proserpinaca pectinata, Utricularia juncea, Brasenia schreberi, Pontederia cordata, Ludwigia spp., Utricularia spp., and Eriocaulon aquaticum.

NatureServe Conservation Status
Global Status: G2 (07Dec1998)
Rounded Global Status: G2 - Imperiled
Reasons: This Coastal Plain pond association has an estimated 100-150 occurrences rangewide, but it is a small-patch community that totals fewer than 1000 acres. Coastal Plain ponds in general are threatened by hydrologic alteration (groundwater depletion), agricultural runoff, and recreation activities.
