    Tree Cover and Urban Land Development: Assessing the Impact of Building Demolition on Tree Removal


    During building demolition, damage and removal of trees on the property is at times intentional and at other times inevitable.  Developers may want land cleared so redevelopment is not encumbered by existing trees. Conversely, developers may retain trees to maximize benefits, which are positively correlated with tree cover.  In this study, we explore whether building demolition results in tree loss in the context of the thousands of demolitions occurring after the earthquakes of 2010 and 2011 in Christchurch, New Zealand.  This study uses high-resolution aerial imagery to measure tree canopy cover prior to the earthquake and ground-based tree inventory following the demolitions to quantify the impact of demolitions on tree cover.

    Justin Morgenroth, Ph.D., MFC, New Zealand School of Forestry, New Zealand School of Forestry, Christchurch, New Zealand

    Justin Morgenroth is a lecturer at the University of Canterbury in New Zealand. He received his Ph.D. from the New Zealand School of Forestry, in Christchurch, New Zealand, and his master's degree from the Faculty of Forestry, University of Toronto. He has also worked as an independent urban forestry consultant, completing contracts ranging from invasive species management to site surveys and tree inventories. Dr. Morgenroth’s primary research interests share the common objective of understanding tree health and survival in urban areas. Previous research interests have included understanding the impact of porous and impervious pavements on underlying soil environment; and determining how these edaphic changes impact above- and belowground growth of street trees. Most recently, he has worked to understand tree response to the altered soil environment following the Christchurch earthquakes.
