Monitoring Change in North America’s Central Grasslands

A Synthesis of Grassland Inventories from Canada, Mexico and the United States

November 21, 2025 52 pages Ecosystems

Grassland loss is one of the most pressing conservation challenges in North America, yet the ability to track this change is complicated by the diversity of existing monitoring systems. This report reviews 33 grassland inventories across Canada, Mexico and the United States, drawing on a literature review and expert workshops held in 2023 and 2024. It highlights differences in definitions, methodologies and accuracy assessments, as well as opportunities to advance consistency through data sharing, collaborative networks and the integration of new technologies and Traditional Ecological Knowledge.

This report is intended for policymakers, researchers, land managers and conservation practitioners.
