In general, and based on the information obtained for each invasive species, the damage to Puerto Rican biodiversity revolves around native species that are threatened or endangered, as well as drastic changes to the ecosystems on which they depend. There is significant competition for space between native and invasive species; damage to vegetation, both terrestrial and marine, either through consumption or modification; and the spread of invasive plants. Additionally, invasive species disrupt the population balance of native species that are threatened or endangered by competing for food or excessively invading their natural habitats, including some that are managed across the island for protection. Examples include the Puerto Rican parrot (Amazona vittata), the yellow-shouldered blackbird (Agelaius xanthomus), the Puerto Rican boa (Chilabothrus inornatus), pollinating bats, the Puerto Rican coquí (Eleutherodactylus coquí), as well as other variations of the coquí species, and many native species of marine fauna and flora. Likewise, these invasive species affect infrastructure by creating burrows that destabilize the ecosystem’s terrain; this effect is also observed in rivers and coral reefs due to invasive fish, crustaceans, and mollusks.
