Well, we finally got this mother of dead beech down. It had died as a result of the neighbor building a septic field, and excavating out the roots. The rot/dead tissue wrapped around in a sort of corkscrew around the tree. It was in rough shape – a risk assessment of ‘Highly Probable’ to fail in the next year, or so. There was sapwood rot with whole lot of tiny little fungus-es were growing out of those branches that were hanging over the house. The central leader/spar was completely dead, and weighed nothing- most arborists accept that you NEVER get to actually tie into a central leader. It’s always some weird, balance-y offset.
So, how do we reduce the danger of these trees? I mean, the central TIP was long dead- so I opted for multiple tie-ins on laterals that came off the central spar lower down. I protect these the same as protecting a climbing ( rock climbing…) route – with redundancy. Lots of slings and carabiners, and lots of Alpine Butterfly’s. This is where SRT is wonderful – you can tie off slings on other branches. If your main TIP fails, then you have other slings and biners to catch you. The rope is static, and therefore your not battling friction like when the DdRT ropes squeeze through a single carabiner.
This willow shows how many ways you can protect the lead (in this case, five tie-in over 20ft). It also gives you the choice of Big Shotting a limb, a known and obviously SAFE limb lower down, then protecting/inspecting the lead as you work your way to a higher TIP.
