Plants and Animals
Plantago cordata Heart-leaved plantain
Large leafy forb of wet forests; leaves broadly heart-shaped, up to 20 cm wide, forming a basal rosette, with the lateral veins of the leaf branching off the primary midvein as opposed the arching from the base of the petiole; flowers minute, densely borne on a long erect or arching stalk.
Status and Rank
US Status: No Status/Not Listed
State Status: E - Endangered (legally protected)
Global Rank: G4 - Apparently secure
State Rank: S1 - Critically 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.
Heart-leaved plantain occurs in large river floodplains, along small, mucky streams, and in rivulets in ravines above streams and rivers.
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.

To protect this species, conserve the hydrology of river systems and corresponding cyclical floodplain regimes. Maintain healthy intact, mature floodplain forest and minimize forest fragmentation. When possible, leave large tracts of unharvested forests and allow natural processes to operate unhindered.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
