Nice work Boa,..we expect no less from you blokes up there, Your first picy on the truck looks like the tree is actually growing out of the back of the truck!..Great pictures.

Thanks John, you know as I've said before I love working with cranes, especially when you get operators who are interested in your techniques and solutions to problems. We had so little room on the second pick of the Fig, I had to cut the base with no real escape route so securing the tree using the portawrap was the only solution, short of removing the tree piece by piece. The dogman form All State Cranes Mike was perfectly happy once he saw the rigging line (7ton breaking strain) and the loopie for the porta wrap (12ton), Stephen Tim and myself always go out of our way to clearly define what we're going to do in a toolbox before anything happens, we document our risk assessments and always always get a majority agreement on the method we're going to use....doing this we have been able to do tricky jobs quicker, smarter and safer......now I just need to find a crane company that will let me rig myself off the ball........ |

Bit of an odd day today, real mixed bag, but variety is good.....thought I'd post these pics of Tim doing hat is probably the only retrenchment pruning to be done in NQ ever! (Well deliberately with both intention and understanding anyway) These are mangos in the soon to be sold Defence grounds Jezzine Barracks Townsville, suspect they are around 100yrs old...we're doing an cyclic program of tree works for Defence and mitigating the risk from dead and decaying parts of these two trees (along with others) is part of that. So some shots of the before during and after with Tim doing all the cutting, well the camera is heavy you know!    But its what was around the stem that caught my eye, now remember I think the tree is around 100yrs old, I also think I know what is going on here I've seen it before in a number of trees in different places....No its not the old big branch injury that hasn't closed though that has resulted in an interesting hollow that extends right up through the tree, its the loss of tissue functionality around almost 60% of the stem..look at the adventitious roots growing out of the bark tissues.    Now obviously its damage, but from what impact of line trimmers? well a possibility but unlikely to create what I can see in the bark tissues, a long spiral like wound travelling almost all the way round the stem circumference...I'll play with MS paint and show you what I see. |

So here's some lines to highlight what is unclear from the photos alone Under the adventitious roots and the woundwood is a patch of bark concealing the old wound, some of the roots have managed to bridge the wound and graft into the live stem tissues below.   Around the other side is the same story in fact it is even more obvious, the bark that has gradually grown over the wound can be easily lifted off but I didnt want to damage any more of the trees tissues   Now I think this type of injury is caused by water cutting into the bark again and again over many years, then the being stopped...either the watering system is altered, removed or discontinued...my quess for a system of the right era would be an early Travelling sprinkler like the Trailco T50 perhaps. Though the age indicated by the size of growth in the adventitious roots might arguably show that it occured much more recently, in which case popups of impact sprinklers would be the culprits. Here's a recent water blasted Alstonia actinophylla  That photo was taken a year ago and the tree has unfortunately not survived (well half of it anyway) I'll try to get a shot of the dead half and the injury site, if council haven't already removed the tree. |

Well, got no worries of that here in Brisbane! Good one though Boa, very interesting, the water eventually cuts through the bark or the pressure just compresses the fibres to the point they die.

Here's some pics of the work we recently did on two Ficus benjamina out at Charters Towers for the Shire Council. The two were part of a planting of three figs along the road edge probably around 100-120yrs old, road renovations/resurfacing and minor landscaping planned by the council raised concerns that these trees needed work. Can't really remember now whether the feeling was they should be removed and hence the council wanted to pass the parcel...or whether residents wanted them protected (suspect now it was the former!! but thats ok as you'll see) One of the three was very badly lopped and affected by fungal decay through the stem entirely...could push a stick right through from one side to the other..this tree is being removed by council. The other two had large stubs from years of abuse (lopping) some problematic elongated epicormic regrowth, sunscald, some confliction low branches and impoverished soils.  So we drove out there and removed all large significant deadwood with targets, lifted the lower branches where over driveways and footpath, reduced the elongation on the worst areas of the canopy where either confliction or the epicormic nature of the regrowth caused concern. Total amount of live canopy removed 10%  .Before  After  Some shots of Stephen working hard  on the pole saw reducing the length of a limb with major confliction where his feet are.  Then based on a comprehensive soil test undertaken when the original Arboricultural report was written, we drenched the soil of the vegetation strip with water containing raw molasses, concntrated fish emulsion, dried seaweed extract, and N-Fix. (I have no photos of us doing that sorry) The best thing about the works we undertook out at the Towers was the minimal impact on the trees, these are figs yes, and have all the genetic advantages over many other species that Ficus have...but one of the three has already fallen to the combination of neglect and malpractice, esential with trees this age in conditions like these to measure your dose very carefully....equally important to ensure the client understands that they are not going to see mounds of cut branches and many wounds to show how hard we've been working! The soil works carried out on these two trees is the key to their long term improvement in health and vigour..our intention is to revisit the two on our way back from treating my special friend out at Hughenden in the next month, I'll take much better pics and more of them on that trip watch this space since as some of you know Veteran trees are my main love and we have so few left in Qld...I'm referring to the Explorers' Tree Hughenden BTW. |

Fridays can be fun..... Along with the two transplants we have been managing on site tree issues for the large scale development going on next to the river here in Townsville for almost two years now. Today we got to ride the basket of the self eresting crane on site to remove deadwood over the construction site, assess the health and vigour of a large older E. tessellaris and generally enjoy the view (ok mostly enjoy the view) The crane is at 50m, the E. tessellaris approx 42m. Stephen going up  Perspective..can you see my house from there???  The tree in question and the site below (and behind)  Enjoy the view......   View of the residential development underway and the open riverside parkland swimming pools, arts centre (soon to be finish international cricket/AFL ground) beyond......the red circle denote the two transplants.  |

Very good Sean. I like the way it works, Steve rides the basket, you can climb.  Hey, did that developer do all that great tree care coz he wanted to or because he was forced to?

They were forced to, the whole development swung on the retention and protection of the existing significant trees, best practice etc... Still lots of problems but a huge step forward for our city.

It has certainly raised the profile of Stephen's business and rightly so. We have recieved more Arboriculturally satisfying work as a result of our envolvement with Riverway Thuringowa. It does make you feel optomistic, mate if Arboriculture can get a foothold here, if we can change (even if painfully slowly and with many steps backwards) the way trees are managed up here it can be done anywhere (and I'm not saying that has happened it hasn't but we've made good progress, and continue to build on what we've done so far..after all we are offering a better way....better in every way, for everybody) Hey its Friday |

Glad you put yourself next to that Ficus. It looked really small at first. But not after seeing the photos following. We only grow them as big houseplants here. |

That poor old tree. I probably wouldn't even dead wood that out there, just let it be with mulch and root care. Is the deck going all around it? You'd still want natural mulch and water through to the ground.

Spot on Eric! No deadwooding, the deck will be constructed just out side the dripline, we spread 10m of mulch whilst we were there (i didn't get photos of it since we were rushing to get our first well earned beer of the day!! The council will spread another 10m inside the fencing.I spread 2kg of humic acid under the mulch which the council will irrigate through the woodchip...the deal with any older/veteran trees is slow and steady, no sudden changes when attempting to improve the soil environment, no nitrogenous fertilisers at all!! Josephine has been surviving in this spot for over 250yrs, and with care will survive another 100+ long beyond my life expectancy |

| Re: Northern Tree Specialists
When gums are stag headed the only type of dead wooding you can do is similar to topping, cut back to live tissue or just the other side. However you go past a year later and it just keep going in many cases. But in some cases when rain comes etc you get the odd bit of growth here and there from that stag head. That's the way of nature, bit of a flush, then die back and so on goes the cycle for a long time. I think the dead branches add to the trees character, dont pose any risk, and highly unlikely that they'll attract some pest that kills the tree. I see them as grey hairs on an old wise tree. The pics below are of a gum across the road. I should have taken more pics of it over the years and watched the decline then bursts of foliage. Now 2 years or so ago I was thinking of cutting of all the dead wood, but it would be most the top, however now with some rain it's about 50% foliated! The reason I didn't push deadwooding onto Mike was it's right down the back corner and pretty much zero risk. The tree in the peak of the drought did get infested with sap suckers and went a little off colour browny yellow. Mike was asking for a topping or deadwooding but what happened a storm and lots of rain was due in a few days and he followed my recommendation to drench (in the rain) with a watering can a dose of Confidor plus seasol. Within a week it was like a new tree and that was 6 months+ ago. These pics I took just this morning, you can see the flushes eminating from what most would have called (and cut off) as dead wood. Being a good arborist is knowing what the options are and doing the best for the tree. In this case Mike want to keep this tree ... he planted it and loves it. But it's in for a rocky future and depending on how long I live here it's like doing a scientific study as the TPZ gets violated with paving, retaining walls and gardens sheds.

| Re: Northern Tree Specialists
Here's some pics of the prep work for 7 small transplants Mimusops elengi along side a road which is being widened to support the ever growing population of our not so little hamlet! Location of the babies  Hydroexcavation and clean cutting of roots   Trenches backfilled  Soil and roots treated with drenches  To our great annoyance the timeline for this little project has completely collapsed down to two weeks!  Why is it that noone wants to commit to engaging the Arborist until the last moment despite being told very clearly that at least 6 months is required to have high confidence of transplant success. |

Yeah, like they decide to cut trees down after they build near on top of them! Shame, but they should do alright those lil guys. Be interesting to see the pics of the transplant etc.

Hey Sean, Impatient developers give you the shytes, With the hydro excavation what psi does the blaster run while trenching the root ball?? I've noticed down here they are starting to protect the exzisting trees during work, Not as big exculsion zone that you really want but better than nothing, I've also seen thin wooden slats wired to the tree to protect it from impact from what ever, It's a step in the right direction.

| Re: Northern Tree Specialists
I think that little blaster works at around 5000psi, they are a very useful tool but you need a good and patient operator....the water can do as much damage as any ecavator bucket in the wrong hands....many operators have years of experience carving their ay through roots and assume thats what you are paying them to do, rather than merely exposing the roots for clean cutting, its slower and messier than what they are used to. When you find a good operator who cares about trees hang onto them!!! Protecting the trunk is occaisionally necessary but really as a last resort, since if there is a real risk of impcting the trunk what is happening to the roots! Always be aware of the greater clearance heights construction plant requires too!! |

Sean, I've used up 3000 psi blasters years ago after an hour or two it gets very hard to hang on to so 5000 psi would try anybody out, I used to be very accurate in what I was trying to do but that was then now....mmmmm...who know's, Just like tree work it looks easy until you jump into the saddle then you realise just how hard it is,When a tradesman makes it look easy, You are really watching a true professonal.

So here's a couple of pages with pics of the small transplants shown earlier being preped.....Remember the Crowded House song Four Seasons in one day?Well this is 7 transplants in one day..we're tired but happy little tree guys!!! Before shot early this morning...  I won't post all 7 since they were all very similar so here's some of the action...      The heaviest tree was under 1 tonne, so pretty easy to handle and manage, although we had a few moments since the original location was restricted by both roadbase and bitumen...very thin rootballs...so very careful does it on the extraction, last thing you want is a bare rooted tree turning upside down above a pile of dirt |

OK, how did you cut roots underneath the ball? Did the lifting slings go right across underneath or just tuck in at the sides? And the last pic, what's that a galv pipe sticking out?

Sorry Eric you posted between sets of pics! The rootballs having grown over the top of very hard (like concrete) road base and in a couple of instances actual bitumen breaking the soil suction was about as easy as I have ever seen...totally excavate the root ball then place bucket on one side and lift....  Three of the trees had low density irrigation pipes running through the root balls so we carefully severed them  . Repairs to irrigation and ALL in ground services were exclusions to our contract (Huzaarr!!!)
