Partnerships between researchers and restoration practitioners can improve restoration outcomes, which is especially important for restoration in challenging settings. Here, we describe one such partnership in the Great Basin, United States, which used trait-based methods and practitioner knowledge to identify the most promising seed sources for restoration. Managers in this region can either use widely-available commercial seeds, which are often sourced from far outside the seeding area, or take extra steps to use locally collected seeds. We asked whether wild-collected seeds of two native plants, Elymus elymoides and Poa secunda, had traits more conducive to seedling establishment in degraded sites, relative to commercial sources. Seeds were collected from four remnant native populations within lands managed by the Winnemucca Bureau of Land Management. Collections were screened for seed and seedling characteristics previously identified as associated with increased seedling performance in degraded Great Basin systems, and we provide a detailed methodology for these measurements. Relative to commercial seeds, wild-collected seeds had more characteristics identified as beneficial for seedling establishment, including phenology, root allocation, root form, and overall size characteristics that suggest locally-sourced populations would be likely to establish better than commercial sources. Using phenotypic traits as criteria, the most promising wild populations were selected for agronomic production to increase the quantities of seeds available for restoration, and field trials are ongoing using these field-increased seeds. These results provide support for collaborative efforts This article is protected by copyright.

使用快速筛选适应性特征来选择本地植物进行恢复：大盆地案例研究中的方法和结果

研究人员和恢复从业人员之间的合作可以改善恢复结果，这对于在具有挑战性的环境中进行恢复尤其重要。在这里，我们描述了美国大盆地的一个这样的伙伴关系，它使用基于特征的方法和从业者的知识来确定最有希望的恢复种子来源。该地区的管理人员可以使用广泛可用的商业种子，这些种子通常来自播种区以外的地方，或者采取额外措施使用当地收集的种子。我们询问了野生采集的两种本地植物 Elymus elymoides 和 Poa secunda 的种子，相对于商业来源，是否具有更有助于在退化地点建立幼苗的特性。种子是从温尼马卡土地管理局管理的土地内的四个剩余土著人口中收集的。对收集的种子和幼苗特征进行了筛选，这些特征先前被确定为与退化的大盆地系统中的幼苗性能增加有关，我们为这些测量提供了详细的方法。相对于商业种子，野生采集的种子具有更多被确定为有利于幼苗建立的特征，包括物候、根分配、根形式和整体大小特征，表明本地来源的种群可能比商业来源的种群建立更好。使用表型性状作为标准，选择最有前途的野生种群进行农艺生产，以增加可用于恢复的种子数量，正在使用这些田间增产的种子进行田间试验。这些结果为协作努力提供了支持 本文受版权保护。版权所有。识别、收集、筛选和增加当地种子资源的可用性，以提高恢复成功率。
