Competing Co-doms..to remove or not to remove

padre · 27th February 2010, 08:01 PM

Hi site users
Has anyone had first hand experience with the outcome of removing a codominant stem in a mature Norfolk Island Pine. We have situation where a tree of normal vigour has 2 co dominants at 24m with DBH's of approx 300mm
1 is slightly superior, they are approx 10m high . I would like to know if anyone has monitored the compartmentalisation at the cut site . The union has some bark inclusion. I am for its removal for the the increased ULE of the tree. What do you think

Instead of looking at a total removal you could go for a co dominant part reduction this will stop the offending limb getting too big and sort out your problem, however pictures would be a huge help in his case.

Have a read.

Twin topped - peaked hoop pine | Suggestions | Subsidence?

Plus pines can be pretty strong, flexible you see not brittle like say grey gum.

How about dynamic cable it so it's also a fall arrest while you reduce slightly the less dominant one .... do read that other thread though.
