Interpretation Guide
Northern white cedar is widely distributed (4.4% of area), sparse, but high IV conifer across the north and some isolated spots mostly in the Appalachians. The models class as 'No change' though they show some loss in habitat. Though our system gives an overall rating of fair for this species to cope, it has regeneration issues in parts of its range due to deer. SHIFT does suggest it appropriate for infill planting.
Family: Cupressaceae
Guild: persistent, slow-growing understory tolerant
Functional Lifeform: medium-size evergreen tree
