Plants and Animals
Piptatherum canadense Canada rice grass
Loosely clumped grass of sandy, moist jack pine clearings; leaves bluish-green and very narrow, with strongly inrolled margins; inflorescence sparse and open, with solitary spikelets, each terminated by a stout curly awn.
Status and Rank
State Status: T - Threatened (legally protected)
Global Rank: G4G5 - Rank is uncertain, ranging from apparently secure to secure
State Rank: S2 - Imperiled

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.
This species is found in pine barrens, particularly within sandy, moist areas that have recently been cleared of their jack pine cover and on the margins of small depressions. Although primarily found in the Upper Peninsula, it can also occur in northern Lower Michigan.
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.
Leatherleaf, blueberry, hair-grass, goldthread, bunchberry, and poverty grass.
Canada rice-grass benefits from soil disturbance to create a moist, open, moderately acid substrate.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
