Nursery industry levy funded research to support Australian standard for landscape tree stock

Researchers at the Hawkesbury Institute for the Environment at Western Sydney University have commenced work on a research project examining the influence of climatic region and species on tree stock balance.
Funded by Horticulture Innovation Australia (HIA) using the nursery industry levy the project was initiated to support an industry commitment to undertake further research of tree stock balance parameters across all climatic regions of Australia in the recently released Australian Standard AS2303:2015 Tree stock for landscape use.
The project is supported by a project steering committee which includes representatives from HIA and Nursery & Garden Industry Australia (NGIA) as well as tree stock growers.

The project team led by Professor Mark Tjoelker has two key components. The first component is to obtain baseline information on treestock balance and performance metrics. This will be achieved through a literature review using trade literature, industry best practice material as well as scientific peer reviewed work.The second component of the project will be to quantify treestock balance in contrasting climatic regions. This will be achieved by conducting field tests with growers across Australia to determine and evaluate the regional and species differences in tree stock balance. From this work it is intended to develop metrics and tools to enable the cost effective and rapid quantification and categorization of tree stock balance.

The outputs of the project will help to support the standard and enable tree growers, buyers and specifiers to produce and purchase and specify trees of high-quality.
