Talking Big: Lessons Learned from a 9000 Hectare Restoration in the Northern Tallgrass Prairie. Article from Sustainability includes a 22 page pdf, downloadable.
“Because of its high agricultural productivity and vulnerability to conversion, temperate grassland is considered the most fragmented, altered, and threatened of terrestrial biomes [1,2]. Recent studies have demonstrated the importance of perennial grassland to the sustainability of soil food-web complexity and stability, regional resilience to climate change, storage of soil carbon, and mitigation of nitrate transport into streams and rivers [3–5]. In North America’s northern tallgrass ecoregion, less than 2.5% of native prairie remains . Furthermore, most remnants are small and shown to be diminishing in size and quality .”
