Marine STAR Metric
A recognised state-of-nature metric to measure marine species extinction risk.
I have experience helping some of the largest companies and financial institutions organise and analyse their data to navigate complex environmental challenges. I have also developed novel methods and contributed to global guidance to facilitate best practice. My work has enabled clients to identify and manage biodiversity risks, set science-based targets, and disclose their impacts and dependencies on nature in line with global frameworks and standards including:
My name is Joe Turner. I am a nature and biodiversity expert with
extensive experience building analytical products and workflows that
integrate multiple datasets. I have over a decade of experience in
data analysis and visualisation (R and Python), including geospatial analysis and mapping.
I have applied these skills to create innovative, best-in-class methods to address
private-sector challenges, produce new service offerings, and create peer-reviewed
publications, guidance, and geospatial layers. I am based in Cambridge, UK, but I work with clients globally.
My career spans governmental, academic, and consultancy roles where
I have a detailed understanding of ecological principles, having worked on projects that
span a variety of ecosystems including mapping and modelling coral reefs during
my PhD, assessing sensitive habitats that have compliance risks in the Arctic circle,
and identifying areas of higher biodiversity risk in coffee-growing forests in Africa.
I am an experienced researcher and able to synthesise the literate into a clear evidence base to inform
decisions.
Outside of academia I have continued to improve the wider scientific landscape, with a particular highlight
being the development of the marine version of IUCN's Species Threat Abatement and Restoration (STAR) metric.
Outside of work, you will probably find me running.
I represented Great Britain at the World 100 km Championships in 2024 and I apply the same level of dedication,
perseverance, and attention to detail to my work as I do to my training.
Selected areas of expertise.
I use R and Python to clean data and build scalable workflows and products for portfolio-scale analysis.
PhD in spatial ecology and published peer-reviewed geospatial products.
Automated biodiversity risk tools aligned with framework requirements and standards.
Expert in biodiversity datasets (e.g., ENCORE, IBAT) and state-of-nature metrics (e.g., STAR, MSA, EII) to facilitate biodiversity assessments.
Led companies through the SBTN pilot and methods to enable alignment and target-setting.
Detailed technical understanding of TNFD, SBTN, GRI, CSRD/ESRS, and ISSB requirements.
Example peer-reviewed publications and technical contributions.
A recognised state-of-nature metric to measure marine species extinction risk.
Developed the underlying methodology for the IBAT Disclosure Preparation Report.
Developed methods to enable companies to assess biodiversity risks across supply chains.
Technical contributer to the IUCN Rapid High-Integrity Nature-positive Outcomes approach.
Contributed to the global screening layer and have a detailed understanding of the application of IFC PS6.
