Shrub of northern beaches and riverbanks; leaves narrowly lanceolate with smooth, inrolled margins, green above and densely silky-hairy beneath.
Status and Rank
- State Status: SC
- State Rank: S2
- Global Rank: G5
|County Name||Number of Occurrences||Year Last Observed|
Updated 4/11/2018. 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.
Satiny willow grows along marshy river banks, and sandy shores. On Isle Royale, it is known from hollows in rocky outcrops.
Natural Community Types
- Sand and gravel beach
- Volcanic bedrock lakeshore
- Northern shrub thicket
- Northern wet meadow
- Emergent marsh
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.
No data are available concerning associates in Michigan.
The primary need for this species is a status survey to obtain much more detailed habitat information. The species likely requires protection of habitat and maintenance of a semi-open condition.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
