At Paperbark Technologies we specialise in custom building tree surveys to meet your needs. We have range of data collection attributes and use Trimble devices to accurately survey each tree using GPS, MapInfo or AutoCAD software. We can also tag each tree on site for ease of identification. We can provide a full inventory of each tree including health, structure, tree valuations, Quantified tree risk assessments, tree problems and remedial works required or basic data depending on your requirements and the project. Please download our brochure for further information or contact us for a quote.

We can assist you with providing technical advice on individual trees or large scale situations requiring reports on health and structural condition of trees, trees interfering with power lines, trees causing root disturbance issues, significant trees, trees adjacent playgrounds and high use areas, trees within development sites and tree protection reports just to name a few.

At Paperbark Technologies we have extensive experience using the Quantified Tree Risk Assessment method. Where a tree poses a risk to a particular target we are able to assess the risk of significant harm from tree failure in order to balance safety with tree values and minimise the risk associated from tree failure.

Tree Safety
Management

What is QTRA?
Tree safety management is a matter of limiting the risk of harm from tree failure whilst maintaining the benefits conferred by trees. Although it may seem counter intuitive, the condition of trees should not be the first consideration. Instead, tree managers should consider first the usage of the land on which the trees stand, which in turn will inform the process of assessing the trees.

The Quantified Tree Risk Assessment (QTRA) system applies established and accepted risk management principles to tree safety management. Firstly, the targets upon which trees could fail are assessed and quantified, thus enabling tree managers to determine whether or not and to what degree of rigour a survey or inspection of the trees is required. Where necessary, the tree or branch is then considered in terms of both impact potential (size) and probability of failure. Values derived from the assessment of these three components are used to calculate the probability of significant harm occurring.
The system moves the management of tree safety away from labelling trees as either ‘safe’ or ‘unsafe’ and thereby away from requiring definitive judgements of either tree surveyors or tree managers. Instead, QTRA quantifies the risk of significant harm from tree failure in a way that enables tree managers to balance safety with tree values and operate to a predetermined limit of reasonable or acceptable risk.
