Tree ListAPPROVED TREE LIST – Small, Medium, and Large H:\CED\Data\Forms-Templates\Self-Help Handouts\Planning\treeslist_march2010.doc P. 1 In the City of Renton there is an overabundance of maple and cherry species. According to the most recent street tree inventory, maples currently comprise 35% and cherry 24% of all species. To reduce a catastrophic loss of species, experts agree that 10% o r less of any species or cultivar exist within a street tree population. Because of this, planting maple or cherry trees within the right -of-way is discouraged.
