Distribution map for Cerastium brachypodum

Updated 7/21/2017. 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 known from rock outcrops and alvar in the Upper Peninsula. Little is known about its specific habitat requirements, and surveys for this recently listed species are needed.

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

Data on associates are currently lacking, but likely includes species typical of its alvar and rock outcrop habitat.

Management

Requires protection of the habitat and perpetuation of natural disturbance (i.e. prescribed fire, wind throw, etc.) and hydrological regimes. Since alvar and rocky outcrops are primarily sedge and grass dominated communities, species found in this community usually do not tolerate later stages of succession and require management that prevents woody plant encroachment, such as prescribed burns or brush removal. This species is likely susceptible to damage from excessive recreational use and foot traffic.

General Survey Guidelines

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