Big Tree Failure

[browncow]

Came across this beauty of a failure today. It appears that a co-dominant, included stem with brown rot has failed into the adjacent tree causing that to fail at the root plate.There are a couple of bracket fungus visible on the standing half of the tree, and the fallen leader is extensively decayed.

couple more

Thats big. Where is it?

[atree]

Yeah big tree,What kind of tree is it.

 

Singapore lancstree

With so many roots in the decay, looks like it could be dropped into a planting hole with a crane again and let it grow again.

 

(Just kidding)

Singapore lancstree

 

Yep Singapore. It is Pterocarpus indicus or Angsana. They are a common street and park tree here. It one of the bigger ones I have seen around and certainly a pretty cool failure.

 

They are usually topped (this one had been) and left to sucker away again. They then top them again every 2 years or so at the height they can reach with the palfinger crane with bucket attached. This one had loads of decay from the stubs and tear cuts in the canopy.

 

We see a lot of whole tree failures here mainly due to high water tables and clay soils (hence shallow roots).

Cool,yeah i can imagine water table being a big issue in singapore,When i was there all the trees seemed to be pretty well looked after,Must be hard working there with the humidity is it?

Not too bad bro, just crank the air-con in the office up:001_tt2: When doing training here or climbing for inspections its pretty hot and there is a lot of critters that like to bite and sting in them thar trees. Were you over here for a bit bro working for one of the contractors?

Were the Howeia (?) palm and (Asplenium ?) tongue ferns rooting in the brown rotted stem of the tree ? If so, they were a preceding warning of the extensive decay and possible fall of the tree.

And the bracket fungus causing brown rot must be an indigenous South Asian species, because it doesn't look like any brown rot causing European species I know.

Yep definately there were warning signs. The decay is visible through the buttress flutes.
