Dr. Baer is considered an expert in grassland, soil and restoration ecology.  The Baer-lab studies above and belowground changes in structure (species and functional composition of plants and microbes) and function (primary productivity, nutrient cycling, and carbon sequestration) during ecological restoration in response to environmental heterogeneity, interannual variability in climate, and intraspecific variation in population sources of dominant species. Much of our research has focused on agroecosystems restored to tallgrass prairie.
