Retrenchment Images

[treeseer]

Nice, thanks! It's refreshing and instructive to see tree management over time. Here in the US the view is constrained; myopic and manic in comparison.

Is this an example?

Just a small oak on todays work list

I would say that's a tree showing retrenchment Josh.

 

roots possibly compromised by the road.

Here's a magnolia that responded to the stressful life in the city by regenerating a new crown.

 

It could also be called natural retrenchment, but that downward adjustment is only the first and least important part of the Growing Downward story, as I heard it from Mr. Green.

The growing part is the long-term focus; maybe that's why the German-inspired terms of Crown Regeneration and Regeneration Pruning are favored in the global scope of arboriculture.

 

The TEP description seems limited to the pre-ancient phase.

 

Semantics, yes, but a bit more.

Even the sign was telling the magnolia to stop growing in the manner it was!

In the states, is a tree like this likely to be pruned toward the inner growth or felled as a declining tree Guy?

Here's a retrenching oak I saw in a country park in Suffolk earlier today, where the lower crown is attempting to find an equlibrium of root growth/foliar energy production

 

Surprised it appears to be maintaining as wide a peripheral branch growth as it is, and not shutting them down as well.

Looks like a big segment.column.rib of tissue below that spreading limb.

 

The magnolia would not be felled--we are not that barbaric over here all the time you know!

 

It will likely be ignored. If it were my job I would be loathe to remove much green unless it's drying out. Maybe in a landscape it would be pruned back to the new inner crown, if the owner wanted a smaller bushier form.

David I would say that's a tree dying of AOD, check whether it's alive in three years time. It doesn't look to be attempting to produce a new inner crown.

[David Humphries]

Maybe Jim, to be honest I didn't get a close up look to see wether it was suffering from typical AOD symptoms like stem bleeds etc.....as the image was taken from my car whilst queuing to get in to a show.

 

Might get the chance to look a bit closer in the future.
