Abstract We examined if reintroduction of grazing with or without burning would enhance succession towards native prairie vegetation on previously over-seeded old-field tallgrass prairie subjected to mowing or burning. We hypothesized that returning grazing and fire to these seeded and old-field sites would change establishment and competitive relationships among plant species to benefit fire-tolerant prairie species. Grazing and burning had neutral effects on native prairie species on the previously seeded and unseeded sites over a study period that experienced 70 % of normal precipitation. Herbaceous group categories included old-field grasses, seeded tallgrasses, other grasses (

德克萨斯州布莱克兰草原干旱条件下计划放牧和焚烧对恢复老田地高草物种的影响

摘要 我们研究了在有或没有燃烧的情况下重新引入放牧是否会增强对先前过度播种的旧田高草草原进行割草或燃烧的原生草原植被的演替。我们假设将放牧和火恢复到这些种子和旧田地将改变植物物种之间的建立和竞争关系，从而使耐火草原物种受益。在经历了正常降水量 70% 的研究期间，放牧和焚烧对先前播种和未播种地点的本地草原物种产生了中性影响。草本类包括老田草、种子高草、其他草（
