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.
