在现在由本地多年生草、引进的多年生草或外来的一年生草，特别是雀麦（Bromus tectorum）占主导地位的牧场上重建大的山艾树，有助于稳定土壤，改善水分供应和养分吸收，增加生物多样性，促进社区稳定和恢复力。重新播种的首要任务是确定该网站本地的大山艾树的亚种，并从类似的网站采购该亚种的适应性，高质量的种子。种子应种植在坚实的苗床上，并压入土壤中，使种子与土壤接触良好。来自入侵物种和其他播种物种的竞争必须通过场地准备和使用适当的播种策略和设备来最大限度地减少。在干旱地区，降雨量往往是决定播种成功的主要因素。播种后监测和认真管理是必要的，以维持林分，并为改善未来的播种工作提供反馈。需要进行更多的研究和技术开发，以更好地估计和保持大鼠尾草种子质量，提供所需的苗床条件，并重建大鼠尾草和相关本地植物的混合群落。
Reestablishing big sagebrush on rangelands now dominated by native perennial grasses, introduced perennial grasses, or exotic annual grasses, particularly cheatgrass (Bromus tectorum), serves to stabilize soil, improve moisture availability and nutrient recyling, increase biological diversity, and foster community stability and resiliency. A first priority in reseeding is identifying the subspecies of big sagebrush native to the site and procuring adapted, high-quality seed of that subspecies from a similar site. Seed should be planted on firm seedbeds and pressed into the soil to provide good seed-to-soil contact. Competition from invasive species and other seeded species must be minimized by site preparation practices and use of appropriate seeding strategies and equipment. Precipitation is often a major factor in determining seeding success on drier sites. Postseeding monitoring and careful management are necessary to maintain stands and provide feedback for improving future seeding efforts. Additional research and technological developments are required to better estimate and maintain big sagebrush seed quality, provide required seedbed conditions, and reestablish mixed seedings of big sagebrush and associated natives.
