Locations of 36 western Canadian or US mule deer (Odocoileus hemionus) herd or management units (Units) included in meta-analysis of harvest (by hunting) management and chronic wasting disease (CWD) prevalence trends during 2002–17. For the meta-analysis, we distinguished units with relatively low prevalence (≤5%; n=32) from those with much higher prevalence (≥11%; n=4) at the beginning of respective analysis periods. See text and Supplementary Material Table S1 for additional details. Underlying CWD distribution is adapted from an online map maintained by the US Geological Survey (2020) and augmented by updated jurisdictional data.
