Preliminary results of the reindeer study (Taimyr-Evenky population) with using ARGOS / GPS satellite system in 2015-2016

The research objective was studying the distribution of marked reindeers on the territory of Evenkia and preparation of recommendations about protection and rational use of the population. The study was performed by the staff of the Chair of Game Keeping and Wildlife Management of Siberian Federal University in 2015-2016. The observations over the movements of 10 wild deer equipped with satellite transmitters of Argos system and also land and aerial surveys of deer were made. Besides, in research taxation, cartographic materials of the state hunting register and also the information received from hunters and hunting users were applied. Having manufactured the determination of the areas in general was carried out on the basis of GIS-technologies. The borders of sites of dwelling, their sizes and also features of movements of animals were determined by the locations received from satellite radio beacons. For the assessment of animals behavior the analysis of speed of their movement as azimuthal straight line between two daily points and on twisting trajectory was made. The maximum duration of receipt of signals with use of new battery blocks in 2015-2016 made 438 and 444 days. Sharp decrease in the number of marked deer happens to be the beginning of spring migration. Average speed of movement of deer was 13.5 km/a day. In recent years two large waves of migration with an interval of 20-26 days have been observed. Total extent of the course of deer according to satellite direction finding for the beginning of the third decade of July from places of marking made 1641.1 km. The location of marked animals represented objective markers of migrating herds' movement, calving sites and their wintering grounds. The possibilities of using the database for complex quality standard of the condition of number and placement of resources of the reindeer of Essen group and also the elements of the environment of their dwelling taking into account biotic, abiotic and anthropogenous factors were shown in the study.
