CRITICALLY ENDANGERED
The actual or projected reduction in population size has decreased by ≥80% over the last 10 years or 3 generations; there are only fewer than 250 mature adults and the numbers are declining, and there is a 50% probability of extinction within 10 years or 3 generations. Critically endangered species are palo santo (Bursera graveolens), spikenard (Nardostachys jatamansi a.k.a. N. jatamansi), sandalwood (Santalum album), guggul [a.k.a. common myrrh] (Commiphora wightii), silver white fir (Abies alba), and agarwood (Aquilaria rostrata) (IUCN, 2018)
ENDANGERED
The actual or projected reduction in population size has decreased by ≥50% over the last 10 years or 3 generations; there are fewer than 2500 mature adults and the numbers are declining, and there is a 20% probability of extinction within 20 years or 5 generations. Endangered species are juniper berry (Juniperus communis), rosewood (Aniba rosaeodora) (Figure 1), atlas cedarwood (Cedrus atlantica), bay laurel (Laurus nobilis), araucaria [a.k.a. callitropsis; faux santal] (Neocallitropsis pancheri), and rosewood [English] (Dalbergia abrahamii) (IUCN, 2018)
VULNERABLE
The actual or projected reduction in population size has decreased by ≥30% over the last 10 years or 3 generations; there are less than 10,000 mature adults and the numbers are declining, and there is a 10% probability of extinction within 100 years. Vulnerable species are olive (Olea europaea), sandalwood (Santalum album), sweet almond (Prunus amygdalus), Spanish cedar (Cedrela odorata), elemi (Canarium luzonicum), Brazilian sassafras (Ocotea pretiosa), Siam wood (Fokienia hodginsii), and agarwood (Aquilaria malaccensis) (IUCN, 2018)
