Christopher Columbus
Since the late 20th century, historians have criticized Columbus for initiating colonization and for abuse of natives. Among reasons for this criticism is the poor treatment of the native Taíno people of Hispaniola, whose population declined rapidly after contact with the Spanish. Columbus required the natives to pay tribute in gold and cotton. Modern estimates for the pre-Columbian population of Hispaniola are around 250,000–300,000. According to the historian Gonzalo Fernandez de Oviedo y Valdes, by 1548, 56 years after Columbus landed, and 42 years after he died, fewer than 500 Taíno were living on the island. The indigenous population declined rapidly, due primarily to the first pandemic of European endemic diseases, which struck Hispaniola after 1519. The natives had no acquired immunity to these new diseases and suffered high fatalities. There is also documentation that they were overworked.
Hispaniola
There are many bird species in Hispaniola, and the island's amphibian species are also diverse. Numerous land species on the island are endangered and could become extinct. There are many species endemic to the island including insects and other invertebrates, reptiles, and mammals. The most famous endemic mammal on the island is the Hispaniola Hutia (Plagiodontia aedium). There are also many avian species on the island. The six endemic genera are Calyptophilus, Dulus, Nesoctites, Phaenicophilus, Xenoligea and Microligea. More than half of the original ecoregion has been lost to habitat destruction impacting the local fauna.
