Abstract

Our newly developed telemetry system, GPS-TX, applied Long-Distance radio communication techniques to track wildlife can track animals using GPS and transmit their locations to a base station by radio in real time. The time lag associated with surveying these location points is less than that for conventional GPS telemetry. After applying GPS-TX to survey bear habitat in the Kitakami Mountains in 2011–2012, we extracted three bears’ core areas within the home ranges. Soon after confirming the core areas, we conducted a field survey. From field survey results for core areas, we inferred the bears’ behaviors with traces left in the forest and the undergrowth status. This report presents a summary of the current circumstances and problems related to tracking bears using this system.
