Justification
A population reduction of at least 30% is estimated based on a decline in range (EOO) and habitat loss to commercial protea cultivation in the past 10-20 years. Habitat loss models predict at least a further 30% reduction in population size by 2025 (Bomhard et al. 2005), generation length 20 years.
