“…Restoration of tropical forests in severely deforested landscapes is a major challenge because the hand‐collection of seeds and seedling production causes a bottleneck, particularly when attempting to represent a large pool of native species and genotypes (Brancalion et al ; Nevill et al ; Jalonen et al ). There are 40–53 thousand tree species within the tropics (Slik et al ) and, as might be expected, the literature is lacking in knowledge of their biology and current distribution.…”

Brazil has committed to fulfilling international restoration goals and to enforcing environmental legislation that will require private landowners to undertake ecological restoration of 21 million hectares of degraded and deforested landscapes. To support a broad range of restoration practices, a well‐established supply chain capable of representing regional plant diversity is essential. This study investigated the restoration species pool in native plant nurseries in São Paulo state, located in southeastern Brazil, and evaluated their geographic distribution, similarity of their plant stocks, and the proportion of species represented from regional floras. Despite a lack of technical assistance and a significant presence of nonnative species (126 species, average 7.5 species/nursery), we found an impressive native species richness in plant nurseries (561 species, average 86.4 species/nursery) from both the Atlantic Forest and Cerrado domains, representing 38–44% of regional floras. There was a huge bias toward tree and shrub species (96.6%) and an absence or underrepresentation of other growth forms, as well as of savanna specialists, animal‐dispersed, and threatened species. The dissimilarity of species observed among the different nurseries surveyed highlights their role in representing regional diversity, which reflects their regional seed collection practices. Effective assistance and training are essential to address issues related to misidentification of species, underrepresentation of most functional plant groups, and the presence of nonnative species, as well as to support the supply chain, which is currently undergoing a market downturn.

“…To implement the use of local seed origins, the geographic delineation of seed zones, within which seeds are to be collected, propagated and sown, may be critical [18,19]. In Europe, the first attempts to delineate national seed zones for herbaceous plants have been made only recently [19].…”

Abstract:The European Union committed to restore 15% of degraded ecosystems by 2020, and to comply with this goal, native plant material, such as seeds, is needed in large quantities. The native seed production of herbaceous species plays a critical role in supplying seed for restoration of a key ecosystem: grasslands. The objective of this work is to provide for the first time a characterization of the sector at a multi-country European level together with key information about the community of native seed users via intensive web-based research and a direct survey of industry participants. Based on more than 1300 contacts and direct surveying of more than 200 stakeholders across Europe, responses indicated that: the European native seed industry consists primarily of small to medium enterprises; responding native seed users purchase annually an average of 3600 kg of seeds with an average expenditure of €17,600; the industry (suppliers and consumers) favours development of seed zones and would participate in a European network for knowledge sharing. This study provides framework principles that can guide decisions in this sector, critical for fulfilling the growing demand for native seed as a primary tool for large-scale restoration on the continent.

“…The establishment of seed production areas (SPA) to enhance the quantity and quality of seeds is a key part of the solution (Broadhurst et al 2015a(Broadhurst et al , 2015bBroadhurst et al 2016;Nevill et al 2016). Seed production areas allow for the large-scale production of seeds of species in high demand for restoration, or those difficult to source, and temper the potential for overharvesting of wild plant populations (Broadhurst et al 2015b;Nevill et al 2016). They may also facilitate production of seeds of threatened species for meaningful larger-scale translocation or restoration programs (Offord et al 2004;Cochrane et al 2007).…”

“…Some unresolved aspects of SPA include the selection of appropriate genotypes for source material (Prober et al 2015), the design of SPA to maximise genetic fidelity of seeds produced, and the consequences of production processes (e.g. irrigation, fertiliser, harvesting) or maternal and climate effects on seed quality and regenerative traits (Broadhurst et al 2016;Nevill et al 2016).…”

Abstract. Seed science is fundamental to many fields of endeavour, from agricultural production, to restoration, and conservation of threatened species and communities. This is especially the case in Australia which has seen hugely increased involvement and outputs from seed scientists across many sectors over the last three decades. This escalation in research is reflected in the program and outcomes of the first National Seed Science Forum that was held in March 2016 and was attended by delegates representing many scientific institutions, industry, non-government organisations and volunteer groups. There were delegates from nine countries, and keynote presentations and workshops by global leaders in seed science. A key outcome of the Forum was the unique opportunity for discussion and collaboration across sectors.
