Mammals of Uvalde County, Texas

  Mammals residing in Uvalde County, Texas are quit varied and diverse.  They range from a variety of rodents, rabbits, skunks, weasels, raccoons, badgers, porcupines, deer, a variety of bats and many more.
  Various species play different roles in ecosystems and some are beneficial to the environment and humans.  For example, bats are extremely beneficial to humans and agriculture because one bat can consume up to 3,000 insects in one night!  Bats also consume insects that carry dangerous diseases such as West Nile virus.  When the balance of nature is offset by human activities some species can be harmful in ecosystems, detrimental to agricultural crops and potentially dangerous to humans.  For example, when rodent populations increase they can consume tons of crops, carry disease and cause fires by chewing on electrical wiring in buildings.  Exotic, or non-native species, often present as a result of human activities, can also greatly alter the balance of nature.  For example, feral pigs consume thousands of small, native animals and are extremely destructive to ecosystems.
  This checklist can be used to document Mammals you observe in Uvalde County.  Some species can be easily observed, such as squirrels and rabbits.  Other species are very secretive or nocturnal and are rarely seen by humans (like weasels).  Some species leave signs of their presence, such as tracks or mark their territory by leaving clues such as scratches, scat or various musk and odors (i.e., bobcats, foxes, skunks, bears & coyotes).  Good luck in your Mammal observations!
