Tall beak-rush (1-1.5 m) of coastal plain marshes; culms clumped, without rhizomes; inflorescence with several large, spreading spikelets; achenes with long bristles and very elongated (1 cm), pointed cap.
Status and Rank
- State Status: SC - Special Concern (rare or uncertain; not legally protected)
- State Rank: S3S4 - Rank is uncertain, ranging from vulnerable to apparently secure
- Global Rank: G4 - Apparently secure
|County Name||Number of Occurrences||Year Last Observed|
Updated 5/16/2016. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.
Tall beak-rush is found in areas with a fluctuating water table such as coastal plain marshes, sandy lake edges, dune swales, seepages, sandy marshes, sandy and peaty edges of wetlands, and intermittent wetlands.

Natural Community Types
For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.
Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.

Lance-leaved violet, bluejoint grass, twig-rush, sedges, bushy aster, black-fruited spike-rush, umbrella-grass, northern clubmoss, panic grass, cross-leaved milkwort, bald rush, tall beak-rush, tooth-cup, netted nut-rush, hyssop hedge nettle, marsh St John's-wort, pipewort, autumn sedge, meadow beauty. Species that may occur on the shrub margin include red maple, black gum, pin oak, black chokecherry, dogwoods, and buttonbush.
This species requires conservation of habitat and protection of the hydrology, including maintenance of cyclical drawdown regime and water table. Maintain moist, open habitat. It is also vulnerable to ORV impacts and dredging and filling activities.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
