Researchers at the University of Idaho assessed techniques for restoration within Palouse Prairie. Methods included removing annual grasses by herbicide applications and supplementing native species recruitment with seeding native grass and forbs. Experiments were conducted in three plant communities, ranging from annual- to perennial-dominated communities. Plant characteristics (percentage of cover and plant density) and specific factors affecting recruitment (soil moisture availability and seed-predation losses) were measured.
