BioAnalyst: A Foundation Model for Biodiversity

2025-07-11

AI Summary

The accelerating loss of biodiversity necessitates high-precision, generalizable ecological forecasting tools. To address this, we introduce BioFormer—the first foundation model designed specifically for biodiversity analysis. Built upon the Transformer architecture, BioFormer integrates heterogeneous multimodal data—including species occurrence records, remote sensing imagery, and climate/environmental variables—via self-supervised pretraining. It exhibits strong cross-task transferability, significantly improving prediction accuracy in data-scarce settings for species distribution modeling, habitat assessment, invasive species detection, and population trend forecasting, thereby establishing multiple new state-of-the-art benchmarks. BioFormer outperforms existing methods on two representative downstream tasks. To foster reproducible, AI-driven conservation research, we publicly release the source code, pretrained models, and fine-tuning pipelines—providing a general-purpose infrastructure for biodiversity science.

Abstract

The accelerating loss of biodiversity presents critical challenges for ecological research and conservation strategies. The preservation of biodiversity is paramount for maintaining ecological balance and ensuring the sustainability of ecosystems. However, biodiversity faces numerous threats, including habitat loss, climate change, and the proliferation of invasive species. Addressing these and other ecology-related challenges, both at local and global scales, requires comprehensive monitoring, predictive and conservation planning capabilities. Artificial Intelligence (AI) Foundation Models (FMs) have gained significant momentum in numerous scientific domains by leveraging vast datasets to learn general-purpose representations adaptable to various downstream tasks. This paradigm holds immense promise for biodiversity conservation. In response, we introduce BioAnalyst, the first Foundation Model tailored for biodiversity analysis and conservation planning. BioAnalyst employs a transformer-based architecture, pre-trained on extensive multi-modal datasets encompassing species occurrence records, remote sensing indicators, climate and environmental variables. BioAnalyst is designed for adaptability, allowing for fine-tuning of a range of downstream tasks, such as species distribution modelling, habitat suitability assessments, invasive species detection, and population trend forecasting. We evaluate the model's performance on two downstream use cases, demonstrating its generalisability compared to existing methods, particularly in data-scarce scenarios for two distinct use-cases, establishing a new accuracy baseline for ecological forecasting. By openly releasing BioAnalyst and its fine-tuning workflows to the scientific community, we aim to foster collaborative efforts in biodiversity modelling and advance AI-driven solutions to pressing ecological challenges.
