Article
Full-text available
The return of vegetation to mined lands often requires broadcast seeding of diverse native seed mixes. However, seeds are highly adapted to germination windows with specific hydrothermal thresholds that maximize the likelihood of seedling survival, and post‐mining landscapes typically offer markedly different hydrothermal conditions than pre‐distur...
Article
Full-text available
Restoration seedbanks have become a key infrastructure resource in efforts to restore damaged and degraded environments across the globe. Large‐scale ecological restoration typically utilises large volumes of valuable, usually wild‐collected seeds, but insufficient knowledge of seed biology (including storage requirements in some cases) and ecology...
