Long-term monitoring of small vertebrates: A review with suggestions
Vertebrate monitoring should consist of following long-term (10 years) patterns of relative abundance and distribution. Examples of long-term study reveal natural population variability and deificencies in short-term study. Index methods that express animal abundance relatively, and as detections per unit measure, are suitable and outlined. Recent experience suggests that combinations of methods can be very effective for herptiles (amphibians and reptiles) and small mammals. Rodent populations should be monitored to cover annual high and low levels, and unconventional techniques should be considered. Biases are different in determining bird abundance than for other vertebrates. Recent monitoring literature is reviewed, and the mistake of assuming animal presence to represent animal needs is discussed. Monitoring plands should relate to the expected frequency of natural events, with accessory information and pilot study necessarily include. Information needs are suggested.
