Tree pest, Tree diseases and Tree Risk assessments.

Good day, I hope everybody had a nice relaxing Christmas. I hope 2017 will be everything that you hope and that your highs are greater than your lows. Landscape plants/trees can be injured by biotic and abiotic agents. Abiotic, or nonliving agents, include environmental factors such as drought, Wet, Snow, Physiological and other non-biological factors, such as insects, pathogens, nematodes, parasitic plants such as figs, Mistletoes and ivy and Viruses. Most of these problems are soil related: abiotic disorders such as water deficits, aeration deficits (Soil compaction) nutritional deficiencies, specific ion toxicities, pH related problems and herbicide injury. Whether the cause is biotic, abiotic or both an accurate diagnosis is almost always needed to remedy the ailment. Some Symptoms and signs could be twig die back, small or sparse leaf foliage and too much dropping of leaves, or small flowers. If left to late the tree will die. Now is the time to get your trees assessed for their health for tree Diseases and tree pests and also checking your tree for structural defects assessing the risk associated with the tree defects.

Tree disputes Land & Environment Court: Tree Disputes

With the increasing pressure on our residential communities; land sizes becoming smaller due to larger homes been built, the properties sizes becoming smaller, no longer the ¼ acre blocks, there are more changes that we will impact upon our amenity forest. When this occurs some of these conflicts are decided in the Land and Environment Court. When considering if you need to resolve your tree issues/disputes the first step many people take is to consult their local council and once this occurs councils will ask for more supporting evidence, this evidence is normally by a Consulting Arborist, AQF Level 5 Arborist. When you hire a consultant you should make sure they have this qualification; you can ask to see their certificate and also ask what method they will use to assess the tree/s. Two of the preferred methods are the International Arborist Associations’ ‘Tree risk Assessments Qualifications’ (TRAQ) and QTRA, this is normally called a Visible Tree Assessment and as stated is only a visible assessment i.e. what can be seen form the ground. The consultant should also have a minimum of 5 years’ experience. This is the minimum information you will need before going to the Land and Environment Court. Although, in most cases you will need more supporting evidence such as an aerial assessment of major limbs and the canopy, a soil analysis and/or identification of the type of decay i.e. white rot, brown rot or soft rot and how these affect the trees structure. It is possible that you may also need to determine the trees internal structure, how much solid timber there by using a Picus Sonic tomography test/s or a Resistograph test. When deciding to continue your case, the more information obtained to support the case the better and when you start the project inform your consultant so they can inform you what may be needed and an approximate cost for the project. The case will be decided on fact rather than emotion because a tree is large and any fear is not reason to remove the tree. However, if the tree is large leaning over your home, with several defects in the trunk and brown rot with only 10% solid timber then this maybe a reason to remove the tree. Also the consultant is there for the tree and not the client. An expert witness has an overriding duty to assist the court impartially on matters relevant to the expert witness’s area of expertise. When discussing issues with your consultant tell them all the information you have so they can decide on the best course of action and discuss with them that you are going to the Land and Environment Court to receive a ruling.

Tree pest of Eucalypt species.

How healthy are your trees is your tree showing signs of stress, have they been attacked by a pest/insect. Some tree Pests such as below can damaged and kill your trees if not treated.
Thaumastocoris peregrinus, Winter Bronzing Bug is a pest of Eucalytpus trees, especially narrow leafed Eucalytpus trees. It is a cytosol feeder of tree leaves, which means it feeds on the inside material of the leaf cells and the cell dies. The leaves cannot do their job of photosynthesis.
The symptoms of insect attack are that the tree leaves turn a silver, spotted yellow to bronze colour. This insect pest can be part of the cause of decline in the tree health of Eucalypts in the Sydney basin.
The infested trees will turn the reddish brown to bronze during winter. If the infestation is severe the trees will start to drop their leaves. Twig and branch dieback may also occur. If this continues it will lead to tree decline and possibly the death of the tree.
Chemical control
In Australia the chemical control option for T. peregrinus is tree injection.

Tree Risk Assessments

Winter is now over and our trees are starting to grow putting on new growth and increasing the weight on branches and trunks, having your trees checked out, by a Professional consulting arborist, although some failures are hard to judge, 90 % can be detected easily and action can be taken cheaply to resolve, it’s better than having your home or car damaged or worst still a love injured after a major failure.

Prevention is better than cure when it comes to managing trees on your property, you are responsible for any damage your trees cause to persons or surrounding property, so having trees on your property comes with the commitment of maintaining them in a safe and healthy condition in our current times.

Sometimes trees that may look damaged or structurally unsafe with a defect in their trunks may still be sound, with the trees sealing over the wound. This wood, called reaction wood, in some instances is stronger than the normal wood of the tree.

To determine the structural integrity of the tree advanced assessments may need to occur, such as an aerial assessment with an Arborist using an Elevated work platform (EWP a.k.a. cherry pickers) or a Picas Sonic tomography, to sound the tree.
