Explanation:

The Puerto Rico became one of the oldest colonies established by Spanish in 1508.  

The decline of the native population in Puerto Rico happened during the invasion of Spanish Conquistador and soldiers.

Diseases brought from Europe  that killed thousands of natives were smallpox, chickenpox, cholera, scarlet fever, malaria, measles, etc

The encomienda system, killing of the natives from Puerto Rican, and forcing them to work in mines were some of the other reason for the natives to decline in their  native regions.
