Summary

EcoVision is an AI-powered framework that processes high-resolution RGB imagery from low-altitude UAVs to monitor salt marsh vegetation and map species dominance. The modular pipeline integrates transformer-based semantic segmentation (SegFormer-B5), connected-component vegetation extraction, and fine-grained species classification using a ConvNeXt architecture. It targets two ecologically significant halophytic grasses, Spartina maritima and Puccinellia maritima, achieving a mean IoU of approximately 0.56 and pixel-level accuracy of 0.96 for segmentation, and an F1-score of approximately 0.99 for object-level classification. Dominance estimates, scored at 2×2m resolution, closely matched quadrat-based field surveys with mean absolute differences below 8%, providing a practical foundation for scalable, high-resolution ecological monitoring.

Key takeaway

For ecological researchers and conservation managers assessing coastal ecosystems, EcoVision offers a robust, scalable method to quantify salt marsh vegetation dominance. You can achieve high-resolution species mapping and track changes with greater consistency and spatial coverage than traditional field surveys. Consider integrating similar modular UAV-AI pipelines to augment your existing monitoring programs, reducing manual effort while enhancing data granularity for adaptive management and early detection of environmental shifts.
