Description: Background The current version of CARI is a compilation of local, regional, and statewide aquatic resource GIS datasets into a standardized, seamless, statewide coverage of aquatic resources employing a common wetland classification system. In addition to this GIS, CARI can be viewed on www.EcoAtlas.org (CARI v3.0, released in June 2024), The CARI v3.0 dataset includes and incorporates data from a number of sources: The National Wetland Inventory (NWI, last released in 2023) of the US Fish and Wildlife Service (no additional releases were observed since then in CA); The National Hydrography Dataset (NHD, last updated in Sep, 2023) of the US Geological Survey, last updated in 2022; San Francisco Baylands Habitat Map 2020 (BHM2020 v1.0 - 2024) 5 regional datasets developed by SFEI’s GIS team using CARI’s standardized, and more detailed, mapping protocols and used to demonstrate the WRAMP framework: San Diego Aquatic Resource Inventory (SDARI v1.1) - 2024 Delta Aquatic Resource Inventory (DARI v1.1) - 2022 San Francisco Bay Area Aquatic Resources Inventory (BAARI v2.1) - 2017 Lake Tahoe Basin (TARIv2.1) - 2016 Laguna de Santa Rosa Plain (near Santa Rosa ,CA. NCARI) - 2013, and Six County Aquatic Resources Inventory (including Sacramento, Placer, Yolo, El Dorado, Yuba, and Sutter Counties, California) developed by the US Army Corps of Engineers (Sacramento District) through federal funding - 2010. Subsequently reviewed and filtered by SFEI to remove duplicates and out of date and lower quality data in 2023.

However, CARI dataset varies in detail and accuracy across the state, and represents different time periods for different areas. Users are advised to get familiar with the level of detail available for their area/s of interest to understand the potentially different levels of mapping details represented across their area/s of interest. Future releases of CARI will incorporate updated data sources as they become available. In order for new datasets to be integrated into future releases of CARI, they must meet the minimum standards discussed in the CARI SOP. The vision for CARI is that it will be used by resource agencies, city and county land-use planners, scientists, and other stakeholders as the go-to map to visualize and summarize aquatic resources in their regions for monitoring, and assessment purposes. As more stakeholders use the online wetland monitoring and assessment tools on EcoAtlas, regional interests will improve the map by editing it. EcoAtlas has an online CARI editing tool that allows users to employ the CARI mapping standards and methods to submit suggested updates by submitting direct online edits or by uploading a KML or GIS file. More information on CARI, including definitions, details and methods can be found online at: http://www.sfei.org/CARI. Description of Updates in CARI version 3.0 CARI v3.0 represents a significant step towards the integration of regional automated wetland mapping into CARI. With this update two automated wetland mapping projects are incorporated: The San Francisco Baylands Habitat Map 2020 and the San Diego Aquatic Resource Inventory. These two projects are two of the first primarily automated wetland mapping projects to be included and represent a foundation for the Institute to continue to build off of in order to pursue timely and scalable wetland mapping that can help with larger accounting of critical wetland and other aquatic resources as well as support change analysis. The update continues to make use of previous advancements in the scripted compilation of a wide range of datasets across the full state. Description of Updates in CARI version 2.2 CARI v2.2 further implements the approach first utilized in v1.0 to automate incorporation of the most recent and highest quality data based on available metadata and spatial intersections into CARI for the entirety of the state, rather than just the coastal HUC watersheds updated in v1.0. Furthermore additional work was done to refine the integration of national and regional datasets and crosswalk it to the CARI classification system. Below are listed some of the specific improvements in this latest version of CARI Integration of the most recent NHD and NWI mapping for the entire state Review and filtering of Six-County data to remove overlapping mapping and only include data that was more recent and accurate than other available data Improve the classification and refinement of lake and depression polygons while integrating features from multiple datasets. Address duplicative mapping, overlaps, and edge-effect artifacts from integration of multiple datasets Integrated wet meadows dataset provided by UC Davis Integrated individual vernal pools mapped by SFEI Salinity classifications for CARI features produced by SFEI Description of Updates in CARI version 1.0 CARI v1.0 represents a significant upgrade to how CARI is compiled. A scripted approach is now employed in order to allow incorporation of the more recent and highest quality regions of different datasets to be identified, using available metadata, and incorporated into CARI. This allows updates to CARI from datasets such as NHD and NWI to be accomplished more easily and quickly. In addition a number of additional datasets are incorporated in order to capture a number of coastal aquatic feature types such as beaches, rocky intertidal, and coastal dunes. For more information please see the CARI SOP which can be found at http://www.sfei.org/CARI. CARI v1.0 was released in September 2022. Description of Updates in CARI version 0.3 BAARI v2.1 (2017) Streams, Wetlands and Baylands were integrated into CARI Stream data from the Santa Clara Valley Water Districts 2004 Santa Clara Valley Creeks replaced the NHD streams in approximately the Santa Clara County portion of the Pajaro River watershed, including the Pajaro river itself and Llagas, Uvas/Carnadero and Pacheco Creek watersheds. These streams were then classified by SFEI as Natural or Unnatural. CARI v0.3 was released in December 2017 Description of Updates in CARI version 0.2 Revised streams and wetlands from TARI v2.1(2016) were integrated into the CARI v0.2 dataset. CARI v0.2 was released in May 2016. CARI version 0.1 CARI v0 was released in June 2014. Description of Attribute Fields in CARI CARI consists of 2 feature classes: Wetlands (polygons) and Streams (lines). The feature attributes serve both to classify the wetland type and to provide information about the source of the data. For more details about attributes, mapping methodology, and the methods of compiling multiple data sources into CARI refer to the CARI SOP available at http://www.sfei.org/CARI. POLYGONS (Previously titled Wetlands) clickcode: an alphanumeric code based on the CARI wetland classification (as presented in Table 1, below). clicklabel: a detailed description of a feature's wetland type. Clicklabel is the most detailed classification provided by CARI. Original classifications from component datasets (see “orig_class'') are translated or "crosswalked” into CARI's classification system. While CARI's component datasets may provide more detail for certain types of wetlands, CARI provides a single statewide classification for wetland types, e.g. "Depressional Perennial Natural Emergent". Major classes within the 'click label' field include: wetlands and (deep) open water. Classes and types include: depressions, playas, estuarine, lacustrine, marine, riverine, lagoon, and slope. name: the name of a particular wetland feature. (e.g. Alpine Lake) orig_dataset: the original source dataset for a feature that was integrated into CARI orig_class: original classification of the wetland in the source dataset. Source datasets (e.g. NWI, BAARI) use different classification systems. The 'orig_class' field preserves that information. organization: the agency or organization that originally mapped the wetland feature orig_dataset_pubyear: The year that the original dataset was published process_adjustment: Notes indicating how the original dataset was adjusted to fit CARI Standards source_data: a description of the imagery or other primary data source, including year of collection, from which the wetland feature was identified and mapped source_estimatedyear: Most recent estimated year of source data from source data field orig_scale: Scale that original dataset was digitized at or image scale legend_headings: In EcoAtlas.org, 'legend_headings' is the value that appears in the legend heading. legcode: a 1-3 letter code signifying the major wetland class, associated with the 'leglabellevel2' field. Provides less detail than 'clickcode'. leglabellevel1: Common terminology for a feature's wetland type. In EcoAtlas.org, Leglabellevel1 is the value that appears in the legend, when you click on a particular feature to identify it, and in analyses of wetland areas generated by EcoAtlas' Landscape Profile Tool. leglabellevel2: Major classification (less detailed) of the wetland classification provided by the 'click label' field. E.g. "Depressional". major_class: General category that distinguishes open water from wetland areas. Corresponds with the first letter of “clickcode”. wetland_class: More specific wetland classification than major class. Corresponds with the second letter of “clickcode” anthropogenic_modifier: Classification that indicates if the aquatic feature’s physical structure has been significantly impacted by anthropogenic activities. e.g a depressional wetland occurring due to water backing up behind a man made berm or levee. Corresponds with the third letter of “clickcode” wetland_type: Wetland type that provides additional wetland classification speciation in the context of the wetland_class. This wetland classification is consistent with CRAM module types. Corresponds with the fourth letter of “clickcode” wetland_subtype: Wetland type that provides additional wetland classification speciation in the context of the wetland class and wetland types. Corresponds with the fifth letter of “clickcode” tidal_modifier: Indicates tidal influence on an aquatic resource. Corresponds with the sixth letter of “clickcode” vegetation_modifier: Indicates the dominant type of vegetation for an aquatic feature. Corresponds with the seventh and last letter of “clickcode” salinity_modifier: Classification of salinity from six classes: Fresh (<0.5 ppt salinity), Oligohaline (0.5-5 ppt), Mesohaline (5-18 ppt), Saline (>18 ppt), Bar-Built (Variable), Undefined. salinity_source: Generalized description of the source data used to assign the salinity modifier. salinity_additional_information: A description of the source data that offers a greater level of detail. lastupdate: the date that the CARI integration script was last run to integrate that feature CARI_id: Unique id for that CARI feature LINES (Previously titled Streams) clickcode: an alphanumeric code for the wetland classification (as presented in Table 1, below). clicklabel: a detailed description of a feature's wetland type. Clicklabel is the most detailed classification provided by CARI. Original classifications from component datasets (see “orig_class”) are translated or "crosswalked” into CARI's classification system. Clicklabel values include: "Fluvial Natural", "Fluvial Unnatural", "Tidal Natural", and "Tidal Unnatural". name: the name of a particular wetland feature. (e.g. Pajaro River) orig_dataset: the original source dataset for a feature that was integrated into CARI orig_class: Original classification of the wetland in the source dataset. Source datasets (e.g. NWI, BAARI) use different classification systems. The 'orig_class' field preserves that information. organization: the agency or organization that originally mapped the wetland feature orig_dataset_pubyear: The year that the original dataset was published process_adjustment: Notes indicating how the original dataset was adjusted to fit CARI Standards source_data: a description of the imagery or other primary data source from which the wetland feature was identified and mapped source_estimatedyear: Most recent estimated year of source data from source data field orig_scale: Scale that original dataset was digitized at or image scale legheader: In EcoAtlas.org, 'legheader' is the value that appears in the legend heading. "Drainage Features" is the only value for legheader. legcode: a 1 or 2 letter code identifying whether the major stream class has tidal influence (TR) or not (R), associated with the 'leglabel' field. Provides less detail than 'clickcode'. leglabel: Common terminology for a feature's wetland type. In EcoAtlas.org, Leglabel is the value that appears in the legend, when you click on a particular feature to identify it, and in analyses of wetland area generated by EcoAtlas' Landscape Profile tool. Leglabel values include:"Fluvial" and "Tidal". major_class: General category that distinguishes open water from wetland areas. Corresponds with the first letter of “clickcode”. CRAM_wetland_type: Wetland type that provides additional wetland classification speciation in the context of the wetland_class. This wetland classification is consistent with CRAM module types. Corresponds with the second letter of “clickcode” anthropogenic_modifiers: Classification that indicates if the aquatic feature’s physical structure has been significantly impacted by anthropogenic activities. e.g a channel that has been straightened through human engineering efforts. Corresponds with the third letter of “clickcode” lastupdate: the date that the CARI integration script was last run to integrate that feature CARI_id: Unique id for that CARI feature
