PART IV
Islands and Conservation
This view across the cemetery of Old San Juan, Puerto
Rico is illustrative of the density of settlement that can
be found in the coastal zones of oceanic islands.
Habitat loss is a key driver of biodiversity loss on many
oceanic islands, and on Puerto Rico has been a key
factor in the decline of the emblematic Puerto Rican
parrot (Amazona vittata), only a few dozen of which
persist in the wild (see text).
