Daubenya stylosa

Assessor: Sarah Schumann

Sensitive in 2010
No
Family
Hyacinthaceae
Reason for the sensitivity status
This genus is currently in demand and of popular interest in international horticultural trade. No particular South African species are known to be threatened by collection of wild individuals.
Exploitation extent
None - this species and its close relatives are not exploited, collected, traded or utilized in a targeted manner.
Justification and references

According to the SANBI Red List Assessment, this species is Vulnerable as it is known from three locations that are potentially threatened by habitat loss and degradation (Marinus & Raimondo, 2011). This genus is currently in demand and of popular interest in international horticultural trade, as indicated by several online marketplace, e-commerce and auction sites. No particular South African species are known to be threatened by collection of wild individuals.

Population vulnerability
Population is vulnerable: size is <= 2500 mature individuals OR the number of known subpopulations is <= 5 OR range is <= 100km2 OR species at risk of localised extinctions
Justification and references

This taxon has an extent of occurrence of 23 km² and is known from three locations (Marinus & Raimondo, 2011).

Targeted demographics
Mature (breeding) and immature individuals are not killed, are not significantly weakened (the harvesting methods do not do harm), and are not permanently removed from the wild.
Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

Few known locations of occurrence and existing potential threats from agriculture and livestock grazing (Marinus & Raimondo, 2011) makes this species highly vulnerable to population loss and if exploitation were to take place, recovery may be poor.
