The entire native population consists of old trees with little successful recruitment for 150 years or so. Until recently, Guadalupe Island supported a large goat population (estimated at 100,000 in 1870, and 5,000 in 2000).
The native inhabitants of Guadalupe Island are primarily aged trees that have not seen new growth or recruitment over a period of approximately 150 years. This is similar to the decline of the island's goat population, which was once estimated at 100,000 in 1870 but had dwindled to 5,000 by 2000.
