Tree species selection for the Halifax urban forest under a changing climate

Abstract

Tree selection is critical to ensuring that urban forests are diverse, healthy, and adapted to the urban environment. Climate is one of the main controllers of plant distribution around the world, so tree species are expected to redistribute as a result of climate change. This research aimed to identify which eastern North American tree species should be most suited for planting in urban areas in Halifax given impending climate change. A database was developed for 57 tree species and 95 tree characteristics to enable analysis of tree species native to eastern North America. The results of previous climate envelope research and the database were used to identify the tree species most suitable for planting in Halifax. Of the 57 tree species examined, 16 were identified as most suited for the Halifax urban forest of the 21st century.
