Title: Constructing Combined Weights for Multi-year Samples in NRI Pastureland Surveys

Abstract: The purpose of the NRI pastureland on-site survey is to collect data to assess the current and changing conditions on pastureland health, native and non-native species, bare ground, and inter-canopy gaps. There have been several changes to the sampling procedure since the survey started in 2013. In this talk, I’ll give a brief summary of some of those changes and then describe how weights are constructed for multi-year pastureland samples.
