- Intervention effect Total legume density was higher in annually burned than in unburned tallgrass prairie.
- Intervention effect Amorpha canescens, Dalea candida and Dalea purpurea had higher densities in burned than in unburned prairie.
- Intervention effect Lespedeza violacea, Psoralea tenuiflora and Schrankia nuttallii had higher densities in burned than in unburned prairie.
- Intervention effect Desmodium illinoense responded negatively to annual fire, the only legume to do so.
- Intervention effect Total legume biomass did not differ between burned and unburned tallgrass prairie.
- Intervention effect Biomass production of Dalea candida and Psoralea tenuiflora was higher in burned than in unburned sites.
- Intervention effect Biomass of other legumes was similar between burn treatments.
- Intervention effect Average individual stem masses of Amorpha canescens and Baptisia bracteata were greater in unburned than in burned prairie.
- Intervention effect Total legume density was higher on lowland soils than on upland soils in tallgrass prairie.
- Intervention effect Total legume biomass was not different between lowland and upland soils in tallgrass prairie.
- Intervention effect Densities and biomasses of Amorpha canescens, Desmodium illinoense and Lespedeza capitata were higher on lowland sites than on upland sites.
- Observation Most legume species show fire tolerance or a positive response to fire in annually burned prairie.
- Mechanism Persistence of legumes in annually burned prairie suggests they may play an important role in the nitrogen budget of this ecosystem.
