IDENTIFYING PLOTS FOR SURVEYS OF PRAIRIE-CHICKENS IN MINNESOTA Michael A. Larson and J. Wesley Bailey SUMMARY OF FINDINGS To explore potential improvements in surveys of greater prairie-chickens (Tympanuchus cupido pinnatus) in Minnesota, we developed this study to determine landscape-scale characteristics associated with plots of land occupied by prairie-chicken leks and to evaluate potential within-year sources of variation in the probability of detecting a prairie-chicken lek, if one is present. The study area consisted of nearly the entire range of prairie-chickens in northwestern Minnesota. Observers visited randomly selected Public Land Survey (PLS) sections (~259 ha) 3 times during April and early May of 2005 to detect leks. Confirmatory analyses indicated that wind speed and cloud cover were negatively correlated with the probability of detecting a lek. Road density was positively correlated with the probability of detection, but it was negatively correlated with the probability of a section being occupied by a lek. Exploratory analyses also revealed positive correlations between occupancy and both grass cover as a proportion of area and the area of all cover types considered as habitat and a negative correlation between occupancy and distance to the nearest known lek from the previous year. Comparing only models that included only covariates for which data are available for all plots within prairie-chicken range (i.e., uncorrected GAP data and other Geographic Information System (GIS) based landscape characteristics), models that included covariates measured at the plot scale fit better than those that included covariates measured at a larger landscape scale in the exploratory analysis, but there was no difference in fit in the a priori analysis. Approximately 13% of sections in the study area were occupied by a lek, but the precision of the estimated abundance of occupied sections was low ( Yˆ = 420, SD = 270). INTRODUCTION 375 Nearly all methods for monitoring populations of greater prairie-chickens, including those currently employed by the Minnesota Department of Natural Resources (MNDNR), depend upon locating leks, or concentrations of the birds at their arenas for breeding displays (i.e., booming grounds) during spring. Surveying a statistically valid sample of leks requires identifying all areas where leks may occur and then sampling to find a number of plots occupied by active leks. The range of prairie-chickens in Minnesota covers approximately 10,000 km 2 , so a major limitation to monitoring leks of prairie-chickens is determining where to survey within that range. The availability of GIS technology and databases of spatially explicit land cover have made it feasible to use landscape-scale habitat criteria to identify areas where leks may occur. Although land cover associated with prairie-chicken leks in Minnesota and Wisconsin have been quantified during previous studies (Merrill et al. 1999, Niemuth 2000, 2003), interpretation and application of those data are problematic. In particular, the previous studies were based on a case–control sampling design, which does not allow inferences about relative probabilities of occurrence (Keating and Cherry 2004). In addition, they did not select active leks randomly or verify nonuse at the randomly selected control locations. Inferences about trends in the abundance of grouse throughout the state require statistically valid samples of survey locations from defined areas in which the species may occur. This study builds upon existing knowledge of landscape-scale habitat criteria that may be useful for identifying plots where prairie-chicken leks may occur, thereby dramatically reducing the area needed to be included in monitoring programs. It also serves as a pilot project for a new survey design that may prove to be more efficient than current survey methods for detecting changes in the abundance of prairie-chickens.
