Plants and Animals
Dichanthelium leibergii Leiberg's panic grass
Loosely tufted grass of dry to wet-mesic prairies and savanna; leaves hairy and wide (1 cm), arising along the stem; spikelets relatively large (3-4 mm long), and covered with long soft hairs (up to 1 mm long); glumes long and sharp-pointed, reaching the middle of the spikelet.
Status and Rank
State Status: T - Threatened (legally protected)
Global Rank: G4 - Apparently 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.
Leiberg's panic-grass is found in dry to wet-mesic prairies, savannas, and openings in oak forest.
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.
Black oak, white oak, bur oak, hickory, big bluestem, little bluestem, Pennsylvania, tower mustard, whorled milkweed, Ohio horse mint, old field balsam, hairy hawkweed, dwarf dandelion, rough blazing star, cylindrical blazing star, blue toadflax, wild lupine, butterfly weed, horsemint, racemed milkwort, panic grass, and Venus looking glass.
The habitat of this species has been severely degraded and diminished. Conservation and restoration of native prairie remnants is necessary. This species likely requires natural disturbances associated with prairie habitat such as prescribed fire and brush removal.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
