Abstract:
The extent of Saltmarshes in North America was estimated by combining datasets from different sources using different methods. These include global, national, and local datasets that were generated from ground surveys, and remote sensed imagery. The current dataset serves as an updated of the previously North American Saltmarshes distribution map published by the Commission for Environmental Cooperation in 2016.

Purpose:
This dataset was created as part of a collaborative effort between the Mexican Carbon Program that conducted an exhaustive search for data updates or new datasets available, as well as coordinate three national workshops with Blue Carbon experts from Canada, the United States and Mexico to retrieve feedback on the best practices to map Blue Carbon ecosystems across North America; and the Commission for Environmental Cooperation that conducted the review and evaluation of the datasets collected, as well as the map integration process and cartographic refinement in collaboration with Ricardo Llamas (rllamas@comunidad.unam.mx)as independent geospatial consultant.
The goal of this datasets is to serve as a geospatial tool to estimate Blue Carbon Sink potential of North America in ecosystems such as Saltmarshes, as well as provide a standardized and publicly available input dataset for various Carbon Budget analyses.

The international, national, and local dataset used in this analysis have known data gaps. In this dataset, the most updated and spatially extended Saltmarshes datasets to our knowledge have been used. Future updates are envisioned as new data is available and new data providers offer spatial information over areas omitted in the current map.
North American 2021 Saltmarshes Distribution, Map Integration Report:
The datasets used for the North America Blue Carbon Maps integration were preprocessed to extract spatial information representing the distribution of Saltmarshes, Mangroves and Seagrasses.
Preprocesses conducted with the Saltmarshes datasets were performed between December 2020 and March 2021.
NOTE: A more complete and detailed report of the North America 2021 Saltmarshes Distribution map is available in the accompanying report “NA BC Cartographic Integration Process.docx”
Preprocessing by dataset:
SM_01. WCMC Saltmarshes Distribution Map
The original data set was acquired from the World Conservation Monitoring Centre (WCMC) that integrates two vector layers: polygons and points.
A “selection by attributes process” was performed to isolate all saltmarshes polygons corresponding to Canada, the United States and Mexico territories. All polygons located in the USA territories over the Pacific Ocean as well as Puerto Rico were deselected. A final saltmarshes layer was exported from the remaining polygons selection.
SM_02. National Wetlands Inventory, Version 2
Based on Cowardin Classification (http://www.fws.gov/wetlands/Documents/Wetlands-and-Deepwater-Habitats-Classification-chart.pdf) used to delineate salt marshes in the 2015 CEC North America Blue Carbon Map, a SQL selection was set up to isolate saltmarshes in the 2020 USA National Wetlands Inventory.
USA National Wetlands Inventory (NWI) Code Definitions table was downloaded from the US Fish and Wildlife Service (https://www.fws.gov/wetlands/data/wetland-codes.html) and used to join all polygon features descriptions to the state-level wetlands shapefiles available through the NWI.
The SQL expression selected all polygons defined as “Estuarine – Intertidal – Emergent – Persistent – Saltwater Tidal”
WHERE “SYSTEM_NAME” == Estuarine AND “SUBSYSTEM_NAME” == Intertidal AND “CLASS_NAME” == Emergent OR “SUBCLASS_NAME” == Persistent AND “WATER_REGIME_SUBGROUP” == Saltwater Tidal
All saltmarshes polygons identified at state-level based on the predefined SQL selection were finally merged into a national saltmarshes distribution file (Alaska and CONUS).
SM_03. C-CAP Saltmarshes USA Northeast
Polygons describing classes related to salt marsh habitats in both New Hampshire and Rhode Island files were selected and exported to new spatial layers. Classes selected were: Brackish Marsh, Dieoff Depression, High Marsh; J.gerardii, High Marsh; Mix, High Marsh; S.alterniflora, High Marsh; S.patens-D.spicata, Low Marsh, Panne, Salicornia spp., Salt Shrub, Short form S. alterniflora, Terrestrial border, Wrack.
New layers were merged in a new spatial layer combining salt marshes polygons from Rhode Island and New Hampshire and names were standardized to avoid different spelling refereeing to identical classes.
SM_04. PEI 2000 Wetlands Inventory
This layer contains different types of wetland areas across Prince Edward Island, including “salt or brackish marshes”. A “select by attributes” tool was used to select all “salt or brackish marshes” within the WETL_TYPE (Wetland Type) attribute. A final layer of saltmarshes of PEI was generated from the selected features.
SM_05. New Brunswick Hydrographic Network (NBHN)
This layer was indicated by Bernie Connors (Land Information Infrastructure Secretariat, Service New Brunswick) as the one that contains more specific information on the wetland types, including coastal marsh attribute. The codes for the attribute description are in a “xlsx” file delivered by Bernie Connors (DNR_DataDictionary.xlsx).
According to the reference xlsx file, CM (Coastal Marsh) = wetlands dominated by rooted herbaceous plants that drain directly into coastal waters and have the potential to be at least partially inundated with salt or brackish water.
As a first processing step, the wetlands layer within the Hydrographic Network set of files was selected (NBHN_0000_03_wl.shp). The WC attribute describes “wetland class”, all “Coastal Marsh” polygons were selected and exported to a new feature dataset.
SM_06. Nova Scotia Forest Inventory
This layer is a combination of county forest inventories of Nova Scotia, all the layers were merged to generate a province-level forestry inventory layer. Saltmarshes are described in the “wetland type” (WC_TYPE) field, code for saltmarsh = S.
Individual files were acquired for Annapolis, Antigonish, Cape Breton, Colchester, Cumberland, Digby, Guysborough, Halifax East, Halifax West, Hants, Inverness, Kings, Lunenburg, Pictou, Queens, Richmond, Shelburne, St. Marys, Victoria, and Yarmouth.
Saltmarshes were extracted from all forest inventories by individual files, that created a collection of individual files of saltmarshes. Those individual files by section were then integrated in a single file of saltmarshes for Nova Scotia.
SM_07. BC ShoreZone Observed Habitat Polygons
This is an updated layer from the BC_ShoreZone dataset used in the CEC 2015 Blue Carbon map. The data was downloaded from the BC Geographic Warehouse Custom Download. By means of a selection by attributes, all polygons with SPECIES_NM equal to “marsh grasses and sedges” and “Salicornia virginica” were exported to a final BC saltmarshes layer.
SM_08. St. Lawrence wetlands classification
The layers used to generate the St. Lawrence saltmarshes distribution were delivered by Environment and Climate Change Canada. The shapefiles used to generate this layer correspond to the estuarine section of the St. Lawrence river. Based on feedback from Guy Letourneau from Environment and Climate Change Canada, some of the shapefiles of the sections used in the 2015 Blue Carbon Map should be omitted as they are not considered as part of estuarine region of the St. Lawrence river. Sections of Quebec, Cap Tourmente, Montmangy, and Orleans that were included in the previous Blue Carbon Map of North America are omitted in this updated version.
Different years in the shapefiles correspond to different mapping efforts based on the date when the source orthoimages were taken. Due to geometry problems reported by Environment and Climate Change Canada, files from 2000 were not used when there were files from 2002 for each section of the River. The process to prepare the final layer of the salt marshes in the St. Lawrence reiver is described below.
1. A new attribute field describing the year of origin of each polygon was added to each shapefile of the preselected river sections.
2. Merge of 12 shapefiles that encompass the estuarine section of the St. Lawrence river.
3. Dissolve all polygons based on their legend description.
4. Selection by attributes of polygons containing the text string “marsh” and export to a final St. Lawrence saltmarshes layer.
Cartographic Integration Process:
As some of the datasets show spatial overlaps, some criteria were defined to deal with overlapping polygons from different data sources and keep as much spatial information as possible.
In order to define the criteria to prioritize sources datasets on areas where information overlaps, the Mexican Carbon Program conducted a series of three national workshops with experts from Canada, the United States and Mexico.
Experts were asked to rank the sources datasets features that should be considered when selecting the sources of information that must prevail over areas with overlapping polygons. Six quality features were evaluated by the experts, comprising:
> Most updated datasets
> Fine spatial resolution over coarse spatial resolution
> Datasets reporting accuracy
> National or regional datasets over global datasets
> Independent research studies over institutional datasets
> Most complete metadata
A group of eleven experts participated in a survey to rank the criteria

As a result of the experts-defined criteria and the characteristics of the information provided by each source dataset, we defined each dataset as authoritative over its corresponding region.
All polygons from the most spatially extent dataset (WCMC global saltmarsh distribution map), that intersected areas already mapped by regional or national datasets were omitted in the integration process. In the United States, regional data from NOAA C-CAP in Rhode Island and New Hampshire were prioritized at regional level over the USA National Wetlands Inventory. Polygons from the latest dataset that intersected with regional data from the C-CAP product data were removed.
These criteria were defined as in most of the cases, the data from local or regional data sources refer to a latest date than the sources data reported by WCMC global saltmarsh distribution map, and in some other cases, the local or regional datasets are the same used in the WCMC global saltmarsh distribution map.
All polygons from each local or regional datasets and the remaining polygons from the that do not overlap with already mapped areas were merged in a final North America saltmarshes distribution map.
Step 01
Selection of all polygons from the WCMC global saltmarsh distribution map that do not overlap other input datasets and generation of a new spatial layer.
Output = WCMC_saltmarshes_laea_final.shp
Step 02
All the layers previously prepared and preprocessed with no overlapping areas between source data sets were merged in a new spatial layer.
> WCMC_saltmarshes_laea_final.shp
> CAN_BC_saltmarshes_laea_final.shp
> CAN_NB_saltmarshes_laea_final.shp
> CAN_NS_saltmarshes_laea_final.shp
> CAN_PEI_saltmarshes_laea_final.shp
> CAN_StLawrence_saltmarshes_laea_final.shp
> USA_NWI_saltmarshes_laea_final.shp
> USA_CCAP_saltmarshes_laea_final.shp
> CCAP_coastal_saltmarshes_laea_final.shp
Output = NorthAmerica_saltmarshes_layers_merge.shp
Step 03
A process of “Multipart to Single part” was applied to the output layer from the previous step. This way, all polygons are individually accounted as single polygons, which will allow to dissolve spatially connected polygons that share the same values in all the attribute fields.
Output = NorthAmerica_saltmarshes_layers_singlepart.shp
Step 04
A “Dissolve” process was applied to the output layer from the previous step. All individual polygons that are spatially connected and share the same values across the thirteen common attributed fields (except area) will break down into new polygons. This way, the number of polygons and the size of the final spatial layer file is reduced. No multipart features creation is allowed in this step.
Output = NorthAmerica_saltmarshes_polygons_dissolve.shp
Step 05
A new field “AREA_SQMT” is created and the area in squared meters is calculated for this field. The area is calculated based on the map coordinate reference system, 1 decimal point and thousands separated by comas are defined.
Step 06
After a final check of attribute table consistency and data display on different GIS platforms, a spatial data file in ESRI “shp” format is generated to provide the final CEC North America saltmarsh distribution map.
Note that, although there are no overlapping areas from different data sources, overlapping polygons within the same input datasets are preserved. (e.g., WCMC in the Baja California peninsula or Environment Canada in the Saint Lawrence wetlands classification).
