Technical Abstract: Rangelands cover a large portion of earth’s land surface. Over half of rangelands are degraded from natural and anthropogenic causes. Because disturbance can occur at any time, it is crucial to know how to manage land after disturbance. In a previous study utilizing cover crops and native grasses, the cover crop reduced exotic grass biomass but had no effect of native grass biomass. This study will evaluate interactions between cover crops and seeded native grasses by monitoring plant density, biomass and soil microbial communities for two growing seasons on a recently installed pipeline in southern Texas. Additionally, a seed burial trial will be conducted to evaluate viability of seeds that differ in their successional status and diaspore morphology. Finally, a staggered seeding trial will be used to test effects of limited diversity and high fitness on restoration success. The study will (1) expand our knowledge of how cover crops affect the establishment of native seed mixes when cover crops and permanent seed mixes are planted simultaneously or separately, and (2) quantify the long-term viability of seeds that represent different seral stages in rangelands. Ultimately, we hope to improve our understanding of the best practices for restoration of rangelands after disturbance.
