The use of automated recording systems can overcome many of the limitations of traditional manual sampling techniques.
"The froglogger is revolutionizing conservation efforts around the world where monitoring is either time-intensive or physically difficult."
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 22 years(1992) ago. Since that time many 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 monitoring frog, bird and other animal populations by the use of the Automatic Recording System (ARS, ARU or Froglogger). There is currently new interest in using the froglogger for monitoring populations of other wildlife such as wolves, coyotes, birds, insects, bats, and various marine species.
The purpose of this automated recording system is to allow ecologists to record automatically the vocalizations of animals in the field where being there in person is prohibitive because of cost and/or time constraints. Sometimes a very large area needs to be monitored requiring multiple frogloggers to be employed. Recordings could include frogs, insects, birds, and mammals or even marine animals using a hydrophone. This system employs a user programmable timer/controller to automatically turn on and off a recorder which time-stamps the beginning of each sampling interval. Future models will include sensors for temperature, humidity, barometric pressure, rain, sounds, cloudy vs. sunny days. The data from these sensors will be time stamped with the date/time of the timer/control unit. The system is self contained, portable, and weather resistant. The froglogger consists of a timer/control unit, a recorder, microphone(s) and a batteries. The unit is setup to record at short intervals usually several times a day. The same schedule is normally repeated each day. The unit is designed to record unattended for weeks or even months depending on the duty cycle which is based on the schedule(s) set in the timer/control unit by the user.
