Aerial inspection

[David Humphries]

whilst takng out Massaria infected branches today, No2 looked a little closer at this hole.

 

Its been home to squirells in the past, but nothing at home currently.

 

Sizeable cavity, which the plane is laying down adaptive tissue to compensate for.

In the 2nd pic something looks flexible and he's looking in--is that a borescope?

 

The wound on the right looks to be closing well but yes on an open grown dominant tree that hollow would be a concern.

 

too bad there are no living branches at that node; even the size the lanyard is on would be helping eh?

No 18" model seen in the above listings...have you seen the video model...looks like $300-350US is a typical price.

 

Has the borescope documented any fungal growth along the inner walls of hollow trees?

Can't really see the need for video for ourselves.

 

Yourself?

 

 

The light of the scope picked up this set of Coprinus growing on the inner wall of a chestnut a couple of years ago.

The images were taken with camera and the light of a couple of phone torches.

 

We've also seen various Ganoderma and un-Id'd resupinate fruiting bodies internally.

I had imagined a video might catch more if it swept the range of possible viewing areas. Also if it had its own light that would be a plus perhaps. Flash on the phone camera rarely gives good results for me in hollows; liking the phone torch usage along with that scope.

Id'ing these resupinate fruiting bodies is the order of the day here. This tree has 21" of sound wood in shell wall, but still cannot get condemnation order reversed.

I like this thread. Thanks for posting. Mr David you are doing great work taking all the time and effort to learn and help evolve proper tree care!

Real glad you find it of interest Mark.

 

its like a whole bunch of colourful multi faceted jigsaw pieces that are both frustrating and a joy to attempt to piece together

 

doubt I'll ever get to complete the puzzle, but its a fine field to learn & share in the process

Great thread David (as ususal:001_cool:), some excellent pics and clear explanations of what you were doing.

 

I seem to be moving further from being able to return to blighty for a visit in the foreseeable...but it will happen hopefully in the next 2yrs.

 

I think those of us who have been doing aerial inspections for any length of time have collected various bits of kit to aid the assessment process, I never had the opportunity to use a 'borascope' but I can certainly see it would have been very useful in a number of high profile trees that were felled (when i and others felt there was no justification based on risk of sig harm).

 

I agree with others who have written how much your work documented here and elsewhere is inspiring and motivational. I can easily imagine the prolonged and continuing 'discussions' you must have with your managers over some of the advice and directions you provide.

 

Being in NZ now I am experiencing another perspective/cultural take on tree management and all that entails!

 

In the end for me like you and Guy and numerous others it is rarely sufficient nor adequate to solely base our management advice on a ground based inspection. Climbing into and touching the tree and its architecture (poking, prodding and scoping the various holes and bumps and lumps) is really the only way to be able to form an informed opinion of the structural (and to some extent functional) integrity of the tree.

I really enjoy putting the pieces of the puzzle together. Just yesterday I was on a proposal and was able to figure why these 7 year old Chinese/Drake Elms were leaning over not growing straight. By asking him about the history of the trees, watering, construction, and other details. These trees were staked/guyed for 3 years. Two years ago he removed the stakes and they began leaning. My conclusion was the trees became dependent on the stakes by not allowing growth of the necessary roots to hold the trees up. Also the lack of structural pruning is much needed. Landed a new customer, learned something, and I am now able to help resolve the issue
