Abstract : The Land Condition Trend Analysis (LCTA) program is the Army's standard for land inventory and monitoring, employing standardized methods of natural resources data collection, analyses, and reporting designed to meet multiple goals and objectives. LCTA data has been used to characterize installation natural resources, evaluate the effects of Army multiple use demands on training lands, ground-truth remote sensed imagery, and as a source of data for land based carrying capacity modeling efforts. A critical element of many of these applications is the ability of LCTA data protocols to detect changes in installation natural resources. This report presents results of a, study that used power analysis techniques to evaluate the ability of LCTA data collection protocols to detect changes in installation resources. The use of information and techniques presented in this report should increase land managers' confidence in conclusions drawn from studies using LCTA data by providing the information necessary to adequately judge the strength of evidence from those studies.
