Duncan Slater- Plenary Speaker

 
Duncan Slater Duncan is the course tutor for the MSc in arboriculture and urban forestry, both on-campus and on-line at Myerscough College. As an academic, his PhD study was in the anatomy and biomechanical performance of branch junctions in trees, concentrating on the hazel (Corylus avellana) as a test specimen. Duncan has recently found the primary cause of bark-included junctions in trees, which is the result of 'natural bracing' - touching and rubbing branches that prevent a junction from experiencing normal loading. This finding informs important changes to tree surgery and tree assessment practices.

Geoffrey Donovan

 
Geoffrey Donovan-877
Dr. Donovan has quantified a wide range of urban-tree benefits. These have ranged from intuitive benefits—reduced summertime cooling costs and increased home values, for example—to less intuitive such as crime reduction. More recently, he has focused on the relationship between trees and public health. He found that mothers with trees around their homes are less likely to have underweight babies, and when trees are killed by an invasive pest, more people die from cardiovascular and lower-respiratory diseases. He is spending 2017 at the Center for Public Health Research at Massey University investigating the impact of exposure to the natural environment on child development.

Howell Davies
 
HD(image2)-360

Howell Davies has an arboricultural background with 23 years’ experience in the tree care, management, and urban streetscape redevelopment in Auckland. He has worked in the practical tree care industry and began his career in the USA, before moving to New Zealand in 1994. He has a Diploma in Arboriculture, with Distinction and awarded the best research topic for his final diploma year.

Howell works for the Auckland Council and has had various roles in council over the last 16 years. He has experience with a number of Auckland’s large urban redevelopment projects. He has worked with a number of specialist teams including, engineers, designers and landscape architects on the development and implementation of specialised tree planter pits in large urban redevelopment of street and park spaces in central Auckland. The designs allow for trees to be incorporated into storm water management structures, as well as providing passive irrigation.

His work is ongoing with council’s urban designers providing input into the design of a range of tree planting devices in urban spaces and is currently working on the city’s biggest infrastructure project that is the CRL (central city rail link) to develop and design space for trees.

In December 2016, Howell took on the new role of Senior Urban Forest Advisor for Auckland Council, and has been busy working on development of a regional tree strategy for Auckland. This has involved consultation with a range of council experts from the Chief Sustainability Office, Parks, Biodiversity and Auckland Transport.

The Forest Strategy for Auckland will be the first of its kind for the region and will be a guidance and reference document based on research and data analysis. The strategy aims to set the direction for the future growth, management and where possible protection of tree cover for the region. The development of the documents is aimed at giving a clear strategic direction for the current and future landscape management of the regions public and private tree asset. Howell will give an overview of the strategies development and discuss the analytical and consultative work that has taken place.

Andrew Benson

 
Andrew Benson-359
I've been working in the arboricultural industry for 15 years, beginning like every good arborist on the end of a pile of brush feeding a chipper. I moved to New Zealand from the UK in 2006 and continued to 'ply my trade'. In 2008 I began a correspondence degree course in arboriculture through Myerscough College and graduated with distinction in 2011. I then worked in Auckland as a consulting arborist with a heavy focus on tree protection and development sites. During this time, I began to question some of the practises relating to root pruning and tree protection that we adopt as an industry. In the absence of finding any other alternatives, in 2016 I set out to find out for myself and enrolled as a Ph.D student at the University of Canterbury's School of Forestry. I've spent the last six months carrying out research in Florida. The talk will follow on from the presentation delivered at the ISA conference in Washington DC, introducing the topic with basic theory and show preliminary results.
