ID 1975 the British Columbia Fish and Wildlife Branch implemented the Management Unit system for controlling and monitoring wildlife harvests in the province. This change in management boundaries should have been accompanied by an intensified data handling system, so that accurate and reliable management indices could be produced for each M.U. This thesis describes a data system that was developed in response to Region 1 blacktailed deer management needs and offers a new approach to wildlife

Management strategies can be tested by manipulating exploitation parameters, such as bag limits and season lengths, to determine their effect on specific wildlife populations. In addition, the system restores and upgrades obsolete data files, thus allowing past harvest trends to be applied to new management zones. Flexibility, for both anticipated changes in resource stratification and unanticipated data needs, is also preserved. Biologists require management estimates for specific areas within M.U.s to manage wildlife effectively at the M.U. level. Each of the 15 M.U.s in Region 1 have been subdivided into between 5 and 32 subunits, depending on area and geography. The total 246 subunits attempt to partition large unmanageable wildlife resources into separate populations of manageable size. A location list or computerized gazetteer was used to automatically assign hunt location descriptions to appropriate M.U.s and subunits. Hew techniques for hunter sample estimates are proposed in this thesis. Mark-recapture methods for determining sampling intensities and the partitioning of large resident areas into resident M.U.s can improve estimates. Different methods for treating multiple mailing stage data are also presented. The data system described in this thesis consists of two parts; 1) the establishment of master data files and 2) the retrieval of data fr [...]
