Class II Trees
Class II trees are "medium" size shade trees that make up the great majority of Boise's urban forest. The term "medium" is relative, as these species grow to be pretty big trees! Information at the bottom of this page generally describes Class II trees, for detailed descriptions about individual species, click the links below, email the City Forester or ask a nursery professional.
If you are having a street tree planted, check the planting work order you received, if "Class II" is indicated, you should choose from the list of Class II trees provided with the work order. If you would like a different Class II species other than those available, check the "Request Planting Permit" box and write the desired tree species down. Please don't purchase trees until Community Forestry has approved the permit.
Here are some Class II species that may be appropriate:
Class II tree usually mature to a height of 40-60 feet tall, with a similar crown spread.
To plant Class II trees, the right of way planting strip must be minimum 6 feet wide.
Fall colors vary between species (and in species). Check the descriptions or email the City Forester for details.
Every species grows best under certain conditions, usually relating to soil requirements and exposure to sunlight. Check your planting site and tree details before deciding.
Some species are more drought tolerant than others, check tree details and know how much you do or can water before deciding. No tree is drought proof, all of these trees need regular watering throughout their lives to remain healthy.
