Tree anchors expressed in kilonewtons

[peds]

Luckily, no trees fell over today, but yesterday's snow-felled hazel stems in clear view across the path a bit lower down didn't inspire confidence.

Today's anchor was 2 cams, a hex, a hedgehog, and a single stout but leany tree. I'd rate it above 16kN, definitely. All tied together with our fancy 6mm aramid cord.

If you want to know about tree strength with vertical loads and Kn numbers - slackliners. Hownottohighline on youtube does a lot of destruction testing. I've done a bit of highlining and a spot we use has two 12" oaks for anchors....nobody ever questioned them  no second tree needed for redundancy and sometimes 2 lines rigged off one tree.
