Asparagus oligoclonos

Threats to this species remain unknown.

The genus Asparagus is included in Annex 1 of the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA), which aims to guarantee sustainable agriculture and food security through the conservation and sustainable use of plant genetic resources for food and agriculture, as well as ensuring the fair and equitable sharing of the benefits arising out of their use (FAO 2009).

This species is not yet stored in Svalbard Global Seed Vault (SGSV Data Portal 2013). However, one accession is held ex situ at the Northeast Regional Plant Introduction Station (Plant Genetic Resources Unit, USDA-ARS, New York State Agricultural Experiment Station, Cornell University), for which its origin is defined as the Republic of Korea but its status (wild or cultivated) is undisclosed (European Cooperative Programme for Plant Genetic Resources (ECPGR) 2007–2010). Also, according to Botanical Garden Conservation International (BGCI 2013), this species has living collections in four botanical gardens worldwide, although the origin and location of the collections are not detailed in this resource (garden locations are undisclosed to protect rare and valuable plant species).

This species is included in the Red Data List Plant Edition (Environmental Agency 1997) as Critically Endangered and the Plant Red List of East Asia as Endangered in Japan (Ministry of the Environment 2007, Kokubugata and Kato 2008–2013). Priorities for this species include research to determine population trend, presence in existing protected areas (as an opportunity to establish active management and monitoring of the species) and threats. Further collection of wild germplasm is also a priority to establishment ex situ collections that are fully representative of the genetic diversity found within this species in situ.
