mnap_eos

Locations of rare plants and rare and exemplary natural communites and ecosystems. Replaces former "Extant_EOs" shapefile. This feature class includes records that ar tracked, for which there is good locational information (including records older than 20 years). Look at the SURVEY_DAT field to see the date of the last observation, as well as the EO_RANK field to see what the quality ranking is of a particular occurrence. Many of the records that were previously excluded are in fact still good (e.g., some of the large peatlands that nobody has visited in the past 20 years). Metadata available in ArcCatalog.

mnap_eos_centroids Locations of rare plant CENTROIDS. Created from mnap_eos_single file to make data more visible. Metadata available in ArcCatalog. 11/2014
mnap_eos_single mnap_eos feature class with multi-part polys exploded into single part (by GOMP). 11/2014
MNAP_historic_Extant_EOs All tracked rare plants and rare or exemplary natural communities and ecosystems that have been documented within the state, and includes historical occurrences and records for all S4 and S5 natural communities and ecosystems, not just exemplary ones. Includes a G (general) and M (minutes) precision records. G precision records are those mapped to an entire township, and generally represent things like old herbarium specimens where the collection info only indicates the town in which the specimen was collected. M precision records have better locational info, but not good enough to say exactly where something was found.
