Conservation Status
The IUCN lists Oryzomys couesi as "Least Concern", because it is a widely distributed, common species with broad habitat tolerance that occurs in many protected areas. Habitat destruction, such as drainage of wetlands, may threaten some populations. In many areas, it is so common that it is considered a plague species. Populations even persist in the Valley of Mexico, as evidenced by a photograph published in 2006. However, it is listed as threatened in Texas, where its distribution is very limited, because of habitat loss. In 1979, Benson and Gehlbach estimated the size of the Texas population to be about 15,000. A 2001 study predicted that climate change would drive the Texas population to extinction, because no suitable habitats would continue to exist. The Cozumel population has declined substantially since the mid 1980s, perhaps due to habitat disturbance and predation by introduced species.
