As part of the Urban Forest Research Group (UFoRG), Hannah is researching the composition and coverage of UK urban forests and quantification and valuation of the benefits they provide to society. She is supporting publication of the Individual Tree Data Standard and a new Practitioners Guide for CAVAT, the amenity tree valuation tool. This work supports government policy for healthy, multipurpose and resilient urban forests.

Hannah studied chemistry (BSc (Hons) and MSc (Research)) at Durham University.
She completed a PhD in atmospheric chemistry at the University of Leeds in 2013, and undertook two post-doctoral research positions.

Between 2017 and 2018 Hannah worked for the Leeds Ecosystem, Atmosphere and Forest (LEAF) Centre where she lead two i-Tree Eco studies in Leeds and contributed to the establishment and monitoring of the Leeds Forest Observatory.

Hannah spent two southern hemisphere summers in Antarctica (2018-19, 2019-20) working as meteorologist for the British Antarctic Survey. In the northern hemisphere summers she worked as a Species Warden for Natural England.

Hannah joined the Urban Forest Research (UFoRG) group in November 2020.

The canopy cover Webmap of the United Kingdom's towns and cities

This paper summarises the results of Forest Research’s citizen science canopy cover webmap. Tree canopy cover was measured by contributors to the project in 5,749 urban wards in the UK using a random sample, manual image classification tool called i-Tree Canopy. The area-weighted mean canopy cover across urban areas in the UK was found to be […]
