ICF Members’ Hour – Does Soil Sealing Affect the Health of Urban Trees?

Join us for our first #MembersHour of 2021 with host Professor Francesco Ferrini, Professor in the Department of Agriculture, Food, Environment and Forestry at the University of Florence.

Session Overview

In this #MembersHour, Francesco will discuss his eight-year research project that began in 2011 with an aim of evaluating the effects of four different pavement systems on two woody species and on soil physical traits. In his presentation, he will describe the results of the long-term measurements of tree growth (shoot and diameter growth, canopy size), phenology (leaf shedding, dormancy outbreak), and physiology (leaf gas exchange, water relations), which have been carried out yearly.

So far, results have shown that soil physical traits have been largely affected by impermeable pavements, with a significant reduction of evaporation of water from soil resulting in the onset of a subterranean urban heat island. Trees from both species have benefitted from higher moisture under permeable pavements and have showed higher transpiration compared to other treatments.

About the Speaker

Francesco Ferrini is a Professor in the Department of Agriculture, Food and Environmental Sciences at the University of Florence in Italy. He teaches classes on planting and management of green areas, arboriculture and urban forestry/green infrastructure and tools and methodologies for climate change mitigation in the urban environment. Francesco was President of the Italian Society of Arboriculture from 2005 to 2011 and won the Fabio Rizzi Award in 2009 for his constant commitment in the research and extension service in the field of Plant Nursery Science and of Urban Arboriculture and for his continuous activity with researchers and contractors all over the world.

Who Should Attend?

This event is exclusively for members of the Institute.

Taking place on Zoom, this presentation will be followed by an interactive Q&A session.

This #MembersHour will take place on Thursday 7 January between 11am and 12pm. You can also join in the chat on Twitter #MembersHour.
