Rangeland occupies 47% of the Earth's land surface and represents a major source of food production. There are 40 million acres of native rangeland in western Canada. Rangeland is crucial to sustain soil quality, enhance the availability of clean water, sequester carbon dioxide and maintain biodiversity. Improper rangeland management practices can cause severe degradation that can lead to irreversible changes of this ecosystem. There is an urgent need for timely information on the state of rangeland for the protection of these resources and long-term sustainability.

牧场占地球陆地面积的47%，是粮食生产的主要来源。加拿大西部有4000万英亩的天然牧场。牧场对于保持土壤质量、增加清洁水的供应、封存二氧化碳和维持生物多样性至关重要。不当的牧场管理做法可造成严重退化，从而导致这一生态系统发生不可逆转的变化。为了保护这些资源和长期的可持续性，迫切需要及时获得关于牧场状况的信息。
