UNDERSTANDING VARIATIONS IN AUTUMN MIGRATION OF NORTHERN WHITE-TAILED DEER BY LONG-TERM STUDY 1 John Fieberg, David W. Kuehn, and Glenn D. DelGiudice ABSTRACT 398 Much of our present knowledge of mixed migration strategies of northern white-tailed deer (Odocoileus virginianus) comes from short-term studies, which limits the observed variation of winter severity, its potential influence on the migration behavior of study cohorts, and our understanding. From 1991 to 2006, we assessed: (1) the incidence of autumn migratory versus non-migratory behavior of 335 adult (>1.0 years old) females; (2) what proportion were conditional versus obligate migrators; (3) the importance of winter severity as a factor affecting the migratory response; and (4) the effect of winter severity and study length on the classification of deer as conditional or obligate migrators and the overall composition of the study populations. Annual winter conditions ranged from historically mild to severe. The annual estimated proportion of deer migrating from spring-summer-autumn range to winter range was positively related to winter severity, and the cumulative probability of deer migrating tracked accumulating snow depths as winters progressed. However, the relationship was highly variable, largely attributable to the annual variation in migratory behavior of individuals radiomonitored for 2-7 years. Importantly, due to the variability of autumn-winter weather conditions, we noted that the proportion of deer we classified as obligate migrators was inversely related to the number of years individuals were monitored. Further, the composition (non-migratory, conditional and obligate migrators) of the study cohort was strongly influenced by the severity of winter conditions in the year of capture, as well as in subsequent winters of monitoring. ______________ 1 Journal of Mammalogy (2008) 89: In Press.
MANAGEMENT-FOCUSED RESEARCH NEEDS OF MINNESOTA’S WILDLIFE MANAGERS – FOREST MANAGEMENT ACTIVITIES J. Wesley Bailey SUMMARY OF FINDINGS Because Minnesota Department of Natural Resources (MNDNR) wildlife managers requested help with evaluating the effectiveness of habitat management techniques, MNDNR Habitat Evaluation Biologists sent 65 research-needs surveys to all area wildlife, assistant area wildlife, regional, and assistant regional managers from all MNDNR regions during January 2008. Of the 65, 33 respondents answered the forest management activities section, with 9, 14, 9, and 1 responses received from Regions 1, 2, 3, and 4, respectively. I asked respondents whether a series of forest management activities and associated practices needed evaluation. When I pooled all responses, 93.9%, 69.7%, 69.7%, 63.6%, and 42.4% respondents stated that forest stand improvements, forest stand burns, brush-openland management, brush-openland burns, and forest openings, respectively need evaluation. Within forest stand improvements, 83.9% of managers ranked regeneration as needing the most evaluation. Regional priorities differed slightly from the pooled results. Region 1 selected brush-openland management as the most important habitat management activity whereas Regions 2 and 3 indicated forest stand improvements need most evaluation. Although these 2 regions selected forest stand improvements, Region 2 and 3 differed in their practice ranking. Region 2 selected thermal cover whereas Region 3 selected regeneration as evaluation priority. Overall, pooled and regional responses indicate forest stand improvements need the most evaluation, specifically those practices that affect regeneration and thermal cover. INTRODUCTION The MNDNR Section of Wildlife created 3 half-time Habitat Evaluation Biologist positions tasked with evaluating and monitoring wildlife habitat across Minnesota. Each research group houses 1 Habitat Evaluation Biologist position: Molly A. Tranel (Farmland), J. Wesley Bailey (Forest), and David P. Rave (Wetland). Because MNDNR wildlife managers requested help with evaluating the effectiveness of habitat management techniques, MNDNR Habitat Evaluations Biologists designed and conducted a survey of management-focused research needs. Our chief objective of this survey was to determine habitat management activities that managers believed warranted evaluation. METHODS 399 MNDNR Habitat Evaluation Biologists designed a survey to determine habitat evaluation priorities of wildlife managers across Minnesota. Recipients (n =65) of the survey included all area wildlife managers, assistant area wildlife managers, regional managers, and assistant regional managers from across MNDNR regions. Microsoft Word format allowed participants to type in their responses and return the completed survey as an e-mail attachment. M. Tranel attached the survey to an e-mail message on 15 January 2008 that briefly explained the purpose and survey completion procedure. After a 2-week period, survey recipients received a reminder e-mail message encouraging completion of the survey. Respondents answered questions individually or as a group (usually no more than 3 people); therefore, some surveys may reflect the opinion of an area office rather than one person. The survey contained 3 sections: forest management activity, prairie management activity, and wetland management activity (Appendix 1). I report forest management results in this summary. The forest management activities section contained 5 broad habitat management activities. Each of these contained practices for managers to rank. I also included a write-in
