Popis: The world is witnessing massive land degradation caused by climate change and various anthropogenic activities. There has been a significant increase in habitat restoration efforts, with demand for seeds to restore these degraded ecosystems in some cases outstripping supply. Traditionally, seeds for restoration activities have mainly been sourced through collections from the wild, but with the growing seed demand, this is increasingly becoming unsustainable. In order to ensure responsible restoration practice, restoration practitioners need to explore other options of economical, ethical and sustainable sourcing of seeds. Ex situ seed banks can leverage their technical and infrastructural capacity to play a greater and more direct role in supporting biodiversity and ecosystem conservation and restoration, particularly through the supply of quality ecologically and genetically suitable seed. In this paper, we review whether ex situ seed banks possess the capacity and competence for supporting habitat restoration and the challenges they are likely to face in these efforts. The review focuses on seed collecting, field-based seed bulking, seed handling and storage, seed quality control as well as experience and capacity in facilitating germplasm exchange. The availability of high-quality germplasm collections of documented provenance and with broad genetic diversity is arguably the greatest resource and asset that seed banks have in supporting habitat restoration.
