Data: Western United States Evidence for a growing population of eastern migratory monarch butterflies is currently insufficient: changepoint analysis R code This R code conducts the main changepoint analyses described in the manuscript titled “Evidence for a growing population of eastern migratory monarch butterflies is currently insufficient”, authored by W. E. Thogmartin, J. A. Szymanski, and E. L. Weiser. The code calculates step and segmented changepoints, checks model assumptions for fitted models, calculates the probability of a >=6.05 ha population given a mean expected population of 3.2 ha, calculates the number of additional years required to provide for a statistically significant trend in the event that the current data are not significant, and calculates the probability of continued increase. Priority sampling locations for the Integrated Monarch Monitoring Program The sampling locations provided here were selected as a two-stage Generalized Random Tessellation Stratified (GRTS) sample (Stevens & Olsen 2004). The first stage of the GRTS draw used a master sample developed by the North American Bat Monitoring Program (Loeb et al. 2015) from a 10 x 10 km grid placed over the conterminous U.S., Canada, and Mexico. Each 10 x 10 km grid cell (hereafter, master cell) was assigned a GRTS rank by NABat. The rank represents the priority order in which master cells should ideally be sampled. For the second stage of the draw, sampling points within a master cell were selected. Each point was defined as a 30 x 30 m cell of the GIS raster that defined monarch-relevant habitat. Sampling...
