A greenhouse study on native and non-native grasses from the Great Basin looks at changes in soil nutrient levels and soil microbes among species. The researchers found that although both native and non-native grasses condition soils, the changes caused by native plants tended to favor the growth of other species, while conditioning by the non-native grasses tended to favor only their own growth. The non-native grasses studied included Bromus tectorum, Taeniatherum caput-medusae, Agropyron cristata, and Aegilops triuncialis. These were compared to the native grasses Elymus elymoides, Pseudoroegmeria spicata, and Vulpia microstachys.
