In Tomakomai Experimental Forest, there are several canopy observation sites, one of them called "Crane site".
We can access the canopy of forest to observe and do operation experiment by canopy gondola.
I engage in forest floor ecology, so I can't ride this gondola usually.
This day, a Dutch researcher proposed me to help his work, I attended with him.
