Before using it for a garden decision, identify what the source mapped and which place the result represents.</p> <ul> <li>A historic range or county list summarizes where a taxon was understood to occur under that source’s rules and date.</li> <li>A specimen or observation map shows documented records. Check the record date, locality, and coordinate precision; one record does not show continuous occupancy.</li> <li>A checklist may state that a taxon is native somewhere in a province or state without assigning it to every county.</li> <li>A modeled distribution predicts suitable or expected habitat under a method. It is not the same as a collected specimen.</li> <li>An ecoregion describes environmental context, while a hardiness zone describes climate relevant to winter survival. Neither is a species-range result.</li> <li>A conservation layer may emphasize rare or tracked features rather than inventorying common plants.</li> </ul> <p>Read the legend and metadata before interpreting color or blank space. The <a href="https://lsa-miflora1-p.lsait.lsa.umich.edu/api/v1.0/homepages_text?id=TheMaps">Michigan Flora map guidance</a> explains that many specimen points were retrospectively georeferenced from locality descriptions and are approximate. Fuzzy centroid symbols can stand for records without usable coordinates; sensitive rare-plant locations may be generalized, and extirpated points are historical. Its <a href="https://lsa-miflora1-p.lsait.lsa.umich.edu/api/v1.0/homepages_text?id=MapCompleteness">county richness page</a> also explains that collection effort varies, so a lower total is not evidence that a plant is absent.</p> https://nativeyardatlas.com/native-status-and-provenance/what-native-to-your-county-means/ Thu, 29 Oct 2026 00:00:00 +0000 https://nativeyardatlas.com/native-status-and-provenance/what-native-to-your-county-means/ <h1 id="what-does-native-to-your-county-mean">What does native to your county mean?</h1> <p>“Native to this county” is a claim about a species and a place. It does not identify the source of a nursery plant, predict whether it will thrive in your garden, or mean that every map uses the same definition.</p> <p><img src="https://nativeyardatlas.com/native-status-and-provenance/what-native-to-your-county-means/range-evidence-layers.svg" alt="A sequence for checking a native-range claim: name and place, range authority, occurrence records, then separate site-fit and lot-origin questions." loading="lazy" decoding="async"></p> <h2 id="name-the-place-and-the-claim">Name the place and the claim</h2> <p>Start with the plant’s scientific name, the geographic unit, and what “native” means in the source. A county map may describe historical range; another reference may report current observations or a status at the state, provincial, or national level. Keep the source date and any taxonomic or coverage limits with the result.</p>
