Scientists don’t know how many species disap- peared before they could be counted. Rabbits and goats introduced in the 19th century devastated the gecko’s habitat, but restoration efforts have made the island more hospitable to the lizard. Egyptian mythology’s iridescent bird, with only a few fully wild col- onies left (in Morocco), is being brought back into its former range, including the Alps. The number of alba- trosses nesting on a moss-covered island plateau in the Indian Ocean has risen; inva- sive mice and disease continue to be a threat. Programs to control predators and encour- age breeding on Mauritius have helped the population climb from fewer than 10 birds in the wild to hundreds.
