The froglogger is revolutionzing conservation efforts around the world where wildlife monitoring is either time-intensive or physically difficult.

     In the past there was a good chance that no matter where you lived you weren’t too far away from an area where you could hear frogs calling.

     That’s changed. The populations of frogs are declining in many areas of the world. Whether in an urban area or in a rain forest there used to be a healthy population of frogs and toads but in some of these areas the populations are declining or in some cases have completely disappeared.

     What’s causing this decline? Evidence points to habitat loss, climate changes, UV radiation, contaminants and pollutants, disease, and predation by invasive species. One question is that while the declines are occurring in urban areas as suspected there are also declines in unsuspected places like our protected national parks.

     More study is necessary to determine what is causing these declines. To do these studies it is mandatory that we have methods of monitoring frog populations. The use of the “froglogger” was introduced in papers by Dr. Michael E. Dorcas and Dr. Charles Peterson over 16 years ago. Since that time various improvements have been made in these automatic recording systems. These instruments are now in use by utility companies, state departments of natural resources, USGS, colleges and universities, NASA, and by independent environmental engineering companies.

     Frogloggers.com is dedicated to providing a method of recording the sounds of frog, bird and other animal populations by the use of the Automatic Recording System (ARS, ARU or Froglogger).
