Summary: The extensive rangelands across the Western United States are threatened by invasive grasses, climate change, and altered fire regimes that can disturb the landscape. The largely semi-arid lands are also important for the survival of species that need undisturbed sagebrush ecosystems to thrive. But most satellite-based land cover datasets don’t offer the kind of detail needed to track small but ecologically meaningful shifts in vegetation that can alter fire regimes and improve habitats. In this episode of Eyes on Earth, we hear about how new EROS data products help fill in that gap.
