We analyzed a three-year consolidated sample of Louisiana hunters’ responses to the Louisiana Game Harvest Surveys (LAGHS) distributed via email and mail in May following the 2016–2017, 2017–2018, and 2018–2019 hunting seasons. To determine whether the distribution modes pro- duced different results, both modes asked identical questions about hunting effort, harvest, and age. We used generalized linear mixed models to test hypotheses about hunters’ days hunted, harvest, representation of age classes, and effect of age-weighting (i.e., weighting responses based on the differ- ence in...

Aerial waterfowl surveys are conducted on major wintering areas to provide regional population indices and determine habitat use of non-breeding waterfowl. Coastal Louisiana supports more than one quarter of the continental dabbling duck population during winter. Thus, consid- erable effort is allocated to monitoring waterfowl abundance in coastal Louisiana with implications for future waterfowl habitat management in the region. We conducted monthly surveys on nine state-owned coastal wildlife management areas and refuges, November–January 2004–2016. Across all sites and survey years, the...
