The Long Term Resource Monitoring Program (LTRMP) sampling design and statistics web pages address LTRMP sampling designs and present LTRMP standard methods for estimating status and trends from the LTRMP probability sampling data. Methods associated with scientific inquiry, a separate arm of the LTRMP and of many monitoring programs, will be tailored to each scientific investigation and are only briefly addressed (see Statistical Models and LTRMP Data).
