Some of the threatened species are down to only a handful of surviving members. Santa Catarina’s guinea pig, native to a single island in Brazil, is down to its last 40–60 individuals, reduced by hunting and habitat disturbance. The Great Indian bustard is threatened by habitat loss resulting from agriculture and human development, and is down to the last 50–250 individuals. "Elaeocarpus bojeri", a flowering plant found only on the island of Mauritius, has fewer than 10 surviving individuals, because of loss of habitat. The Baishan fir ("Abies beshanzuensis"), native to China, is down to five surviving mature individuals. "Priceless or Worthless?" describes the threats that each species is facing, and measures that would help their survival.
