Henrik Sjöman

Henrik Sjöman
Work as a teacher and researcher within the field of plant knowledge, vegetation construction, and plant design. Responsible for several plant selection projects together with the Swedish Nursery Industry with the aim to select trees and shrubs for public as well as private greeneries. My main research direction is towards selection and diversification of urban forestry with several ongoing research projects dealing with understanding plants capacity to grow and perform well in different urban environments additionally with their capacity for delivering different ecosystem services. For more information; see publications. Works halftime at the Swedish University of Agricultural Science (SLU), and remaining halftime as a Scientific Curator at Gothenburg Botanical Garden.
