One of the biggest considerations when designing a threatened species monitoring program is deciding how to survey populations across space and time. Too little effort invested in surveys can mean that trends or important changes in populations may not be detected when they occur, and too much effort is a waste of resources that could otherwise be spent on management. Power analysis is a useful tool for assessing:(1) how likely it is that a monitoring program will detect important changes in a species distribution and/or abundance;(2) the level of sampling effort required to detect changes with a desired degree of confidence; and (3) the
