New research published today in Nature Ecology & Evolution demonstrates the extraordinary value of Earth’s remaining intact forests for addressing climate change and protecting wildlife, critical watersheds, indigenous cultures, and human health. Yet the global policy and science communities do not differentiate among the relative values of different types of forest landscapes—which range from highly intact ones to those which are heavily logged, fragmented, burnt, drained and/or over-hunted—due in part to the lack of a uniform way of measuring their quality.
