Simon TARR

I am a strategic and technical leader with a commitment to using data and technology to drive global conservation efforts.

As the Red List Data Manager at the International Union for Conservation of Nature (IUCN), I oversee the technical delivery and direction of the IUCN Red List of Threatened Species™, one of the world’s most authoritative sources on biodiversity status. My role bridges science, technology, and policy—ensuring that the systems, data pipelines, and platforms behind the Red List are robust, scalable, and FAIR, enabling better access, integration, and use of biodiversity data worldwide.

With a strong foundation in data engineering, software development, geospatial data analysis, and ecology, I bring a comprehensive skill set to digital transformation initiatives within the conservation and Green Tech sectors. My expertise spans system architecture design, data integration, API development, and leading cross-functional teams to deliver impactful and reliable digital solutions.

I thrive at the intersection of data, product, and purpose—shaping delivery, supporting people, and building systems that drive smarter, faster, and fairer decisions at scale. By collaborating closely with scientists, policymakers, and private-sector partners, I drive innovations that support informed, data-driven conservation decisions globally.
