IUCN Red List R Package

About This Project

Started in September 2024, this project originated when rredlist was still tied to the deprecated IUCN Red List V3 API. By January 2025, rredlist had transitioned to support the V4 API, introducing substantial structural changes. I continued developing my own approach, which led to redlist — a standalone client designed around consistent tibble outputs and streamlined workflows.

In parallel, there is also the official IUCN-supported package iucnredlist, which provides direct access to the same V4 API. Although these packages all use API V4, they differ in design: redlist focuses on a fresh, independent approach with uniform inputs and outputs for all endpoints, while iucnredlist represents the official reference implementation.
These differences mean the packages are not in competition but are complementary, serving different user preferences.
