Distribution map for Lycopodiella subappressa

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 clubmoss is found in seasonally flooded wetlands in shallow depressions and potholes in glacial lakeplain landscapes. Recent changes in taxonomy split a previous species into two closely related taxa and has resulted in confusion over which entity previous observations refer to. Thus, distribution maps and county lists may be particularly inaccurate for this species.

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

Bog clubmoss, northern prostrate clubmoss, beak-rush, yellow-eyed-grass, lance-leaved violet, panic grass, haircap moss, grass-leaved goldenrod, autumn sedge, mountain mint, seedbox, sundew, Canada rush, boneset, bugle weed, tooth-cup, and prairie willow.

Management

This species requires the protection of habitat and maintenance of hydrology. It is susceptible to excessive recreational use, ORVs, 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.
