What is PBGJAM?

PBGJAM is a NASA funded project which assimilates biodiversity and habitat data to predict species and community response under climate change; develops a web-based forecast of climate vulnerability for scientists, managers, and decision makers; and transforms high-dimensional biodiversity and remote-sensing data into near real-time risk predictions.
Automated Workflows

Automatic assimilation of biodiversity and remote sensing inputs ensures up-to-date and accurate predictions across the US

Bayesian Modeling

Generalized Joint Attribute Modeling (GJAM) fits all species jointly, ensuring robust community and species level predictions

Risk Prediction

Our models forecast community reorganization under climate change, with information for decision makers & scientists

Interactive Web Map

Allows the public, decision makers, and scientists to explore, visualize, and download our forecast models

Developer Version

With tutorials and code available, you can leverage our models and workflow to incorporate and augment your own data


We seek to achieve the highest standard in our work, and make available all our code to ensure our models are accurate
