Nurse log gap space

Microphones and camera points at a fallen tree gap in the Maeyama Conservation Forest, Hokkaido Experiment Forest, University of Tokyo, Furano, Hokkaido, Japan. The stereo microphone and webcam were placed at 2m above ground level at the base of a fallen tree in the Maeyama Conservation Forest, 600m above sea level, where two large trees have fallen and left a gap (called the fallen tree gap). This is a flat area surrounded by Ezo spruce and Abies sachalinensis, and buried under taller-than-height Kumaizasa (Sasa veitchii). There is no power supply at this location, so we use solar power to recharge our batteries and transmit local nature sounds and photos via the satellite network. The solar panels and satellite network antennae are installed in a treeless meteorological stall, and a webcam is placed here at a height of 2m above the ground.
