需要大量多样的和适当适应的本土植物种质来促进全球的恢复，但短缺可能会阻止恢复获得所需的物种多样性和结构。美国发展了一个广泛的本土植物产业来帮助满足这些需求，但对其支持种质需求的能力知之甚少。为了更好地了解目前的能力和种质资源的可用性，我们报告了美国本土植物产业的第一次全面和定量评估的结果，其中包括全国至少841家供应商以及他们提供的可用于恢复的物种。我们综合了来自美国本土植物供应商的商业可用物种列表，并确定了物种可用性的差距，以告知种质研究，开发和生产。在原产于美国的约25，000种维管植物分类群中，26%被商业化销售，其生长形式、保护状况、分布和分类学显著地预测了可用性。相比之下，大约3,000种天然非维管分类群中只有0.07%被商业化销售。我们还调查了中西部高草草原地区的供应商如何满足对种质的需求，以支持高质量的恢复工作，几十年来，该地区一直是恢复工作的广泛目标。在这个发达的本土植物市场，1,000多种目标物种中有74%是商业上可获得的，通常来自宣传遗传多样性的供应商，当地来源的种质。我们提出建议，以高草草原地区等区域市场的成功为基础，填补已确定的空白，包括投资研究以支持生产，确保更一致和明确的需求，以及促进区域合作。
Large quantities of diverse and appropriately adapted native plant germplasm are required to facilitate restoration globally, yet shortages can prevent restorations from attaining desired species diversity and structure. An extensive native plant industry has developed in the United States to help meet these demands, yet very little is known about its capacity to support germplasm needs. To better understand current capacity and germplasm availability, we report results of the first comprehensive and quantitative assessment of the native plant industry in the United States, which includes at least 841 vendors nationwide and the species they make available for restoration. We synthesized lists of commercially available species from native plant vendors across the United States and identified gaps in species availability to inform germplasm research, development, and production. Of the approximately 25,000 vascular plant taxa native to the United States, 26% are sold commercially, with growth form, conservation status, distribution, and taxonomy significantly predicting availability. In contrast, only 0.07% of approximately 3,000 native nonvascular taxa are sold commercially. We also investigated how demand for germplasm to support high‐quality restoration efforts is met by vendors in the Midwestern tallgrass prairie region, which has been targeted extensively by restoration efforts for decades. In this well‐developed native plant market, 74% of more than 1,000 target species are commercially available, often from vendors that advertise genetically diverse, locally sourced germplasm. We make recommendations to build on the successes of regional markets like the tallgrass prairie region, and to fill identified gaps, including investing in research to support production, ensuring more consistent and clear demand, and fostering regional collaboration.
