En este mapa se muestra la distribución de hábitats de marismas, manglares y lechos de pasto marino de América del Norte. Los datos con base en los cuales se elaboró se compilaron de alrededor de 50 conjuntos de datos de fuentes internacionales (como el Programa de las Naciones Unidas para el Medio Ambiente [PNUMA-CMCM]), nacionales (el Servicio Geológico de Estados Unidos [US Geological Survey], el Inventario Nacional de Humedales [National Wetlands Inventory] de Estados Unidos y la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad [Conabio] de México) y estatales o provinciales, además de información aportada por investigadores a título individual. Esta versión correspondiente a 2021 constituye la tercera actualización a la cartografía de la Comisión para la Cooperación Ambiental (CCA) de hábitats que captan y almacenan carbono azul, y responde a una de las prioridades del proyecto Fortalecimiento de la capacidad adaptativa de áreas marinas protegidas, del Plan Operativo 2019-2020 de la misma CCA. Si bien el mapa actualizado representa la imagen más completa de la distribución espacial del carbono azul a escala regional lograda a la fecha, todavía quedan numerosos hábitats de lechos de pasto marino y marismas por cartografiarse, de manera que los esfuerzos para completar esta tarea siguen en marcha, y se prevén varias actualizaciones pendientes del material. Los detalles sobre las fuentes se proporcionan en la documentación sobre metadatos adjunta.
La carte du carbone bleu en Amérique du Nord illustre la répartition des habitats de marais salés, de mangroves et d’herbiers marins sur le continent nord-américain. Les données ont été compilées à partir d’une cinquantaine de sources internationales et nationales, dont le Programme des Nations Unies pour l’environnement (PNUE-CMSC), la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Conabio, Commission nationale sur la connaissance et l’utilisation de la biodiversité), l’United States Geological Survey (USGS, Service géologique des États-Unis) et le National Wetlands Inventory (NWI, Inventaire national des zones humides) des États-Unis, ainsi qu’à partir de sources étatiques et provinciales, mais aussi grâce à des informations fournies individuellement par des chercheurs. Cette version de 2021, qui représente la troisième mise à jour des travaux de la CCE en matière de cartographie des habitats de carbone bleu, constituait une priorité du projet intitulé Renforcement de la capacité d’adaptation des aires marines protégées, entrepris dans le cadre du Plan opérationnel pour 2019 et 2020. Bien qu’au moment de sa publication cette version présente l’illustration la plus complète qui soit de la répartition spatiale du carbone bleu en Amérique du Nord, de nombreux habitats d’herbiers marins et de marais salés ne sont pas encore cartographiés. Des travaux à cette fin sont en cours, et plusieurs mises à jour sont en instance de publication. La documentation ci jointe sur les métadonnées donne de plus amples détails au sujet des sources de données susmentionnées."
The Commission for Environmental Cooperation (CEC) is an international organization created by Canada, Mexico, and the United States of America under the North American Agreement on Environmental Cooperation (NAAEC), which came into force at the same time as the North American Free Trade Agreement (NAFTA). The CEC was established to address regional environmental concerns, help prevent potential trade and environmental conflicts, and to promote the effective enforcement of environmental law. As of 2020, the CEC operates in accordance with the Environmental Cooperation Agreement, which entered into force at the same time as the CUSMA/T-MEC/USMCA trade agreement. 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. 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 Mangroves, as well as provide a standardized and publicly available input dataset for various Carbon Budget analyses. The extent of Mangroves in North America was estimated by combining datasets from different sources using different methods. These include global and national datasets that were generated from remote sensed imagery. The current dataset serves as an updated of the previously North American Mangroves distribution map published by the Commission for Environmental Cooperation in 2016.

The extent of Mangroves 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 Mangroves distribution map published by the Commission for Environmental Cooperation in 2016. * Datasets used in the North American 2021 Mangroves Distribution Map. A more detailed description of all the datasets used, as well as the preprocess performed to extract Mangroves information is available in the accompanying document “Blue Carbon Map sources data notes 2021.pdf”
Preprocesses conducted with the Mangroves datasets were performed between December 2020 and March 2021. NOTE: A more complete and detailed report of the North America 2021 Mangroves Distribution map is available in the accompanying report “NA Mangrove Cartographic Integration Process.pdf”
Global Distribution of Mangroves USGS (2011) A “selection by attributes process” was performed to isolate all mangrove polygons within 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.
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 ---------------------------------------------------------------------------- Name -- Institution -- Email Nate Herold -- NOAA -- nate.herold@noaa.gov Margot Hessing-Lewis -- Hakai Institute -- margot@hakai.org Gail Chmura -- McGill University -- gail.chmura@mcgill.ca Dan Mulrooney -- Parks Canada -- dan.mulrooney@canada.ca Anna Hilting -- NOAA -- anna.hilting@noaa.gov Ma.

The Mexico Mangrove Distribution map and the Disturbed Mangrove distribution map produced by the National Commission for the Knowledge and Use of Biodiversity (CONABIO) were the defined as the only authoritative source over Mexico. Thus, mangrove distribution data provided by the WCMC map was not used as input layer over Mexico. Mangrove polygons form both mangrove distribution and disturbed mangrove distribution over Mexico spatially complement each other without any overlapping, thus, no further processes were required prior the use of these layers for the North America Mangrove distribution map. Step 01 All polygons from the WCMC Global Distribution of Mangroves corresponding to USA territory were selected and exported to a new spatial layer. Output = WCMC_mangroves_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_mangroves_laea_final.shp > MEX_mangroves_laea_final.shp > MEX_disturbed_mangroves_laea_final.shp Output = NorthAmerica_mangrove_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_mangrove_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_mangrove_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 mangroves distribution map.
This dataset shows the global distribution of mangrove forests, derived from earth observation satellite imagery. The dataset was created using Global Land Survey (GLS) data and the Landsat archive. Approximately 1,000 Landsat scenes were interpreted using hybrid supervised and unsupervised digital image classification techniques. See Giri et al. (2011) for full details. > Preprocessing A “selection by attributes process” was performed to isolate all mangrove polygons within the United States and Mexico territories.
