A bit like CSI, sometimes identifying tree species can be a tricky business.  Some trees have really subtle differences and depending on the season, you may not always be able to identify the exact specie without calling on a higher power….science! Here at Tree Logic we have a range of technical diagnostic instruments and resources to undertake many of the basic testing that is needed at part of or typical consulting works.  These include pH and EC meters, Munsell Soil Chart Kits and Plant Tissue Index charts and various sampling devices.  Occasionally Tree Logic consultants come across plant problems that require additional diagnostic services.  There are a range of industry bodies and private companies who have specialised diagnostic services for such tricky plants.  By working in collaboration with scientists we find the solutions to particular problems.

Species Identification:

If we find a specimen that is so rare or unusual that the individual consultant and the team back at Tree Logic cannot identify it either at Genus or Species level even after referring to a wide range of technical books and computer programs, such as our featured tree we might send our sample to the National Herbarium for identification.

Pest & Disease Identification:

Occasionally our technicians will find a pest or a disease of a tree that is difficult to identify or unable to be seen when suspected. For example, fungal diseases such as Fusarium Wilt, Amillaria and Phytophthora can be difficult to identify in many situations and often the best practice is to send a sample of plant, root and soil off for expert analysis.
Unusual pests or pest that are difficult to see with the naked eye can also be sent or taken for a fee,  to service diagnostic laboratories.

Leaf & Tissue Analysis:

Tree Logic sometimes has the need to understand the nutrient status of a plant so that we can best detect a deficiency or recommend fertilizing to treat a particular nutrient issue.  Prior to any recommendations for treatment Tree Logic will often obtain a plant leaf or tissue analysis so that levels of macro and micro nutrients are understood and any deficiencies can be confirmed.

Tips for Preparing Your Samples

Samples need to be properly bagged and labelled.  It is best to telephone the organisation prior to sending off samples to learn the correct process.

Tree Logic Services:

Tree Logic also has a range of technical equipment that we use to diagnose certain tree and plant issues.  We can now offer these services on a casual basis when additional information is required in particular situations.

1.  Sibert DMP™ Decay Detection Drill:

This decay detection works in the same manner as a Resistograph but with the added stability of a continuous pressure reading to add a further degree of accuracy to the readings.  This resistance to penetration is recorded digitally and the information provided indicates the presence and extent of wood decay as well as dendrological information.  The information can be displayed graphically to aid in understanding of the findings.

Tree Logic can undertake Sibert DMP™ Decay Detection works as part of a stand-alone inspection or combine it with an aerial canopy inspection.

2. Chlorophyll Fluorescence Measuring:

Chlorophyll fluorescence can be used to investigate the health status of leaf samples of the plant. Chlorophyll fluorescence works on the principle that photosynthesis is one of the core functions in the physiology of plants. The functional state of photosynthesis has been considered an ideal physiological activity to monitor the health and vitality of plants.  Tree Logic uses a HandyPEA portable fluorescence spectrometer to obtain fluorescence values from the sample leaves and then comparing these to a health sample to compare and assess the health status.

Tree Logic can undertake these works including sampling, testing and interpretation of fluorescence values and plant health.
