The National Red List Project set out to create a one-stop-shop for all things national red list. One of the core elements is the National Red List Database (NRLD), which hosts species conservation assessment data applied at sub-global levels. These include:

• Sub-national: An administrative subdivision or area within a country
• National: At country level, within political borders
• Regional: Multiple countries or at biogeographical scale

Please note: IUCN-coordinated Regional assessment projects (e.g., IUCN Europe Regional Assessments) are hosted directly on the IUCN Red List website and are not replicated within this dataset. The IUCN is not responsible for this website.

The National Red List Project is committed to developing a framework whereby national entities can independently curate and update their data within the NRLD. Your patience is appreciated as we navigate this transitional phase. We are actively pursuing additional resources to expedite the development process and welcome suggestions and collaborations.

To share data, you will need to join or create a Data Stewardship Group and complete and return the Data Sharing Agreement Form available for download below. This confirms you have permissions to share data and agree to its use on the NRL website. Please also review the Terms of Use (Version 2022.1, PDF).

Data Agreement: By submitting data, you confirm that you are the owner of all data being provided or have the necessary permissions to share them. In doing so, you agree to the Terms of Use. If the data include plant assessments, you consent to their inclusion in the ThreatSearch database hosted by Botanic Gardens Conservation International (BGCI). You also agree that you may be contacted for data validation purposes.

Whilst we strive to host an inclusive database for all forms of sub-global conservation status and extinction risk assessments, we have data standards to encourage consistency and support interoperability. Each assessment should include the following:

• Taxonomic information (what organism was assessed)
• The assessment criteria system used
• The geographic scope (country or locality details)
• The assessment status (category assigned)
• The year of assessment
• Source publication citation

If these essential data are missing, we cannot host the assessment.

New update: The NRL Database Guide – Preparing Your Data (Version 2025.2) is now available. This guide provides a full overview of the upload process, mandatory fields, taxonomy standards, and validation requirements. Please use this guide together with the Excel spreadsheet template (v.2025.1) to prepare and transfer your data.

Step 1: Download and Prepare

• Download the latest NRL Database Guide.
• Download the Excel spreadsheet template.
• Gather your data in a tabular format and ensure all essential fields listed in the template are completed.
• Assign unique IDs to each assessment and publication for tracking.

Step 2: Validate Your Data

• Transfer your data into the uploader Excel file following the field definitions in the guide.
• Perform final checks for transcription errors.
• Save your file in .csv format using a naming convention such as:
  MMYY_Firstname_Lastname_country.csv

Step 3: Submit Your Data

• Log into your account.
• Select your Data Stewardship Group.
• Follow on-screen instructions to upload, validate and submit.

Your data will be reviewed by your Data Stewardship Group’s Lead Contributor before being published. We cannot accept data without written confirmation that you agree to the Terms of Use and Data Contributor Agreement.
