Data from Potential Tidal Marsh Migration in Maine project, Don Cameron (ME Natural Areas Program) and Peter Slovinsky (Maine Geologic Survey), 2014. See "Marsh Migration_Final Report_MNAP_March 2014.pdf" for details. No metadata provided with data. Analysis based on Highest Annual Tide vs PHIM analysis which is based on Mean High Water.

_Tidal_Marshes_Final Tidal emergent marshes in Maine greater than 2.5 acres, as determined by MNAP. Generally fringing salt marshes (salt marsh with width less than 60 ft) were not included. 3/2014
HAT_1ft Sea Level Rise Simulation for the entire coast; current Highest Annual Tide (HAT) plus 1 foot. 3/2014
HAT_2ft   3/2014
HAT_3ft   3/2014
HAT_6ft   3/2014
SLR_Nat_Ag_Dev_1ft Sea Level Rise simulation clipped to estuaries that currently support tidal marshes. HAT plus 1 foot. 3/2014
SLR_Nat_Ag_Dev_2ft   3/2014
SLR_Nat_Ag_Dev_3ft   3/2014
SLR_Nat_Ag_Dev_6ft   3/2014

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. 5/2015
mnap_eos_single mnap_eos feature class with multi-part polys exploded into single part (by GOMP). 5/2015
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.
MNAP_mega_ecosystems Contains 2 very large ecosystems, a Central Hardwoods Oak Forest at Mt. A and a Spruce-Fir-Northern Hardwood Forest on MDI. Metadata available in ArcCatalog. 10/2009
