カエデの伐採(雪上重機編)

Felling maple trees (heavy equipment on snow)

The maples selected on April 3rd were cut down on April 18th.

There is still snow left, so heavy equipment can be put on slopes without forest roads. This is a rare task even on a national scale. Because it is a slope along a stream, a river flows below. Not only is there a lot of snow, but the temperature drops below freezing at night and the snow becomes tight.

For felling, dig the snow at the base, crawl into the hole and use the chainsaw. You can't escape easily, so you need skill. A logger from the Uonuma City Forestry Cooperative worked carefully while checking the situation many times.

Measure the trunk diameter and height immediately after defeating. The accumulation of these data will become the basis and calculation for continuous forest utilization.

After measurement, the log is cut to about 4.2m and transported by heavy machinery. As expected, this size cannot be slipped off by human power even on snow.

I got a beautiful white material. These logs are sawn and dried before they reach Storio. I wonder if it will be used from around the summer. I can't wait to see what kind of wood grain it will show!
