“…For example, federal management agencies can commission the large-scale production of seeds directly from growers via a type of contract called indefinite delivery/indefinite quantity or IDIQ (Riley et al 2015). This type of contract allows for lower-risk production of seeds from untested, uncommon, or potentially challenging species or populations by seed producers, providing flexibility in seed availability in particular regions (Peppin et al 2010).…”

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 local, 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 to identify, collect, screen, and increase the availability of local seed sources to improve restoration success.

“…Its goal is to increase seed availability and develop the knowledge and technology to restore native plant communities across millions of acres of burned lands, with a focus on restoring native sagebrush habitat and increasing native forb production. Partners in the Colorado Plateau (Wood et al 2015), Mojave Desert, and Pacific Northwest (Riley et al 2015;Erickson 2008) are conducting similar programs.Through BLM ecoregional programs alone, seed from more than 200 native plant populations have been made available for restoration projects, conservation gene banking, and commercial markets (DOI BLM 2009). To ensure coverage across the United States, these or similar programs will need to be established in areas of the U.S. where they currently do not exist.…”

The Plant Conservation Alliance (PCA) is a public-private partnership of organizations that share the same goal: to protect native plants by ensuring that native plant populations and their communities are maintained, enhanced, and restored.The PCA Federal Committee, chaired by the Bureau of Land Management, developed the "National Seed Strategy for Rehabilitation and Restoration 2015-2020" in cooperation with Federal and non-Federal partners.

Establishing plants from seed is often a limitation to restoration success in semi-arid systems.For restoration purposes, managers 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.If local seeds have traits more conducive to seedling establishment in degraded sites, they could increase restoration success. Here, we asked whether wild-collected seeds of two native perennial grasses, Elymus elymoides and Poa secunda, had more favorable characteristics than commercial sources. Seeds were collected from four populations within the Winnemucca District of the Nevada Bureau of Land Management, which manages lands within the Great Basin, US.Collections were screened for seed and seedling characteristics associated with increased plant performance in invaded 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 earlier emergence, higher specific root length, more root tips, and smaller overall size (E. elymoides), and earlier emergence, longer roots, higher root mass ratio, and more root tips (P. secunda). Commercial sources had significantly larger seeds than wild populations, a trait that had mixed effects on performance in previous research, and one that may change as wild collections are increased in agronomic conditions. These results suggest that locally-sourced populations are more likely to perform well in invaded areas, providing support for efforts to collect, screen, and increase local sources of seeds to improve restoration success. Author contributions:EL, SB, OB, RB, and MW conceived and designed the research; SB and AA performed the experiments; EL analyzed the data; all authors contributed to writing and editing the manuscript. Running head Seedling traits for restoration Implications for Practice• Collecting and increasing local seeds requires more time and effort than purchasing commercially-available seeds, but if these sources have a greater chance at surviving in restoration sites, this effort is warranted • In our study, remnant local populations possessed more potentially adaptive traits than commercially-available alternatives, indicating they may be superior sources for the restoration of disturbed sites in their local regions • Screening multiple seed sources for potentially adaptive seed and seedling traits can be a relatively quick and effective way to select the most promising seeds for increase
