Installation of Artificial System Support
The questions that can come to his mind are: what is the branches stabilized one, why and when it is used?
As the proper word indicates, the technical nurseryman will decide about certain cases to stabilize the arboreal structure. All this in case of clear rupture risk. NaturClimb avoids to realize courts of big section; from 20 cm. These cuts, they debilitate to the tree and propitiate the entry and appearance of pathogenic agents and parasites. This situation will affect the sanitary and mechanical state, and therefore, will shorten its life expectancy.
One of the main targets of the stabilized one, is that in case of rupture and fall of the branch, the ropes system prevents its arrival to the soil.
In the following youtube linkage, two facilities realized on cherry trees can be visualized. In both cases, the putrefaction of the sustained branch is clear. It is a question of preparing and of reducing the break risk and at the same time, of making sure that in case of break, the branch should not reach the soil.
Another illustrative video of an installation of semi-static artificial support, which passed several years has been decided desintalar. The inclusion that had the oak copy, practically in the base of the tree, it has become possible to close and it has stopped suppurating. Although, we understand that it owes more to the installation with cable of steel that was realized at very little distance of the above mentioned inclusion and that he has decided to be supported for the time being.
The cases in which NaturClimb can make use of the stabilized one of branches by means of a system of ropes or cables of steel are for the following “defects” exist.
Wounds and Structural Defects
A branch is well anchored, when at the level of the insertion with the trunk or another ramification, the fibers of both axes interweave forming a clean union axis. This is not the case of the enclosed named branch.
The inclusion is characterized by the insertion of two branches in V. In the top, there appears a crust that prevents the fibers from joining and meeting.
The successive layers of wood that will be appearing do not come to solaparse but they settle one on other one, this way a few sobrecrecimientos will take place to every side of the distinguished axis of union often for a central fissure.
Namely one imagine a cut produced by an operation and sewed with big stitches, where it might appreciate and to distinguish perfectly a lip to every side of the cut joined by the points.
In certain cases, the forces derived from the growth of every branch take part in the fibers rupture and to the imagining of the trunk, with or without effect of the wind.
It stems or formed by an effort of cizalladura, a torsion or a push-up. It is very important her to detect quickly, so the danger it will be permanent and it can be enlarged by the effects of the wind, ice or an intense evapotranspiration, that is to say in the periods of more cold and more heat.
The fissures are recognized outwardly by tripe of healing or cortical superficial distensions according to the type of position of the branch.
They are in many cases, difficult to detect, for staying like internal distortions and in case of species with the rough crust its identification is much more complicated.
Necrosis and putrefactions
The necrosis and the rottenness stem from wounds that the tree has received, of the agents development parasites (fungi and insects lignívoros, etc.) and for incidences of climatological type (ice, water stress, I border, etc.).
Tree to install system of artificial support. Although the vigor of this big branch is indisputable, its awful mechanical state does not leave place to the doubt.
The mushroom lignívoro that the parasite is the Inonotus rickii, very aggressive on having provoked in the wood the white putrefaction, that for the weight and length of this one, we are capable of affirming its fall in a brief time period.
In case of not being ready to do the payment that supposes the system, he proposes valizar and to signpost properly the pedestrian step along the risk that supposes a branch under these circumstances.
The entry and colonization of this so aggressive mushroom has taken place of course for realizing courts of big dimensions, on having lost big part of its photosynthetic capacity for the cut branch, the tree allows to die in many cases part of the wood that it possesses live to be able reequilibrarse at nutrition level.
Hollow formed inside a branch as a result of the agents performance parasites (fungi and insects, etc.). To proceed to the consolidation of branches of a tree that presents one or several cavities can become a danger for the rest of the structure of the tree.
In this case we can visualize a big cavity, practically in the base of the tree and at the same time as there is compartmentalized one, in this case an ash-tree, so that the putrefaction of the mushroom has not affected practically the rest of the tree (dark circular spot).
The branch of the oak, Quercus alba, has a double cavity to different heights. The pruning on continuations deprives to the whole branch of the tree of branches. This reduces drastically its photosynthetic capacity; in certain cases, he usually drives to the fact that the proper tree retires to the branch.
The owner covers a high risk of fall of this branch of big freightage. NaturClimb advises to realize a double anchoring of the branch before cutting it. The first one in triangulation with the pitchfork of the domineering axis. The second double to 45 grades from the first cavity.
The slenderness of a branch or its relation length / diameter
There are habitual interventions when a side or horizontal branch is excessively slender and the technical nurseryman appreciates that there is rupture risk for push-up. It depends to a great extent on the arboreal species and on the vigor of the tree.
¿Why does appear the Structural Defects?
Inside the frame of the maximum respect to the arboreal vegetable patrimony, NaturClimb uses and develops the last skills and materials. All this to consolidate branches or trees of big freightage with high rupture risk. It can be produced for:
- natural factors (beams, excess weight in horizontal branches, process of union or welded in pitchforks, cavities, etc.)
- prunings incorrect that in most cases produce pernicious consequences in the longevity and vigor of the arboreal element
The drastic prunings provoke courts that the tree will not have heal capacity. In other cases, and being still capable of cicatrizar, it will do it with cavities in its interior. These consequences will be hardly diagnosticables for the technical nurseryman, on not having been able to evaluate its state and consequences from the exterior.
Materials to consolidate to the Woodland
NaturClimb is specializing in the use sane dynamics (10-20 %), semi-statics (2-5 %) or wiring of (static) steel. It depends on the specific place from which the branches “sewing” is going to settle.
The use of wiring of steel, it is named statically. It does not allow the free movement between branches. The dynamic one allows him certain freedom, but nevertheless it reduces them between 80 and 95 %.
In certain cases, there can be used ”props” that strengthen and prop big horizontal branches up. It imitates the development of roots air that certain vegetable species develop; as for example, a big number of Ficus spp., Scheflera arborícola, etc.
In the image of the hut, it is possible to know by intuition the installation of a static system of support. Measuring is to support up to 12 tons in weight in case two feet on which the hut is supported and suspended tend to be opened by the weight of this one. Especially when he has to support punctual charges of temporary character: persons who spend the night or when cases of strong winds happen. In this location the mistral usually provokes damages in wooded masses.
The estimated weight of the hut is two tons and a half. From its construction, the client detected as in the base and line of union between two feet of the oak, a cracking was taking place. In French it is named, “fourche d’ecorce inclu” or included crust. It is one of the main reasons at the time of taking the decision to do this type of facilities.
Example of propped up by a big development of branches and pitchforks in the horizontal plane. The tree is going to develop reaction wood in the low part of the branch on having been a species caducifolia. This type of wood is going to sustain the weight without major problem, any time its sanitary and mechanical state is good. Namely if the state of the tree is vigorous, the tree would not need to be propped up.
Although it is not possible to appreciate in the photo, the second work was realized over the hut. He installed to 2/3 parts of the distance to himself between the weak point and the entire height of the tree, a semistatic cordage in triangulation. This one limits the big movements of the glass in case of strong winds.
