Distribution map for Stellaria longipes

Updated 1/31/2017. 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.

Habitat

This species is found on sand dunes along Great Lakes shores.

Natural Community Types

Methodology

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.

Associated Plants

Dune willow, balsam poplar, sandbar willow, ground juniper, sand cherry, beach heath, sea rocket, wormwood, Pitcher's thistle, beach pea, sand cress, Lake Huron tansy, common milkweed, hairy puccoon, beach grass, dune grass, fescue, wood lily, horizontal juniper, northern white cedar, western moonwort, daisy leaved grape-fern, and prairie moonwort.

Management

This species requires protection of habitat and maintenance of natural dune processes (e.g. shoreline fluctuation, erosion, sand deposition, wind, water level fluctuation, sand movement) that create the necessary microsites. Protect habitat from residential development. Control invasive species. Vulnerable to ORV damage and also to excessive foot traffic.

General Survey Guidelines

Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
