Interpretation Guide
Paper birch is a widely distributed (9.2% of area), dense, high IV species across the northern section of the country, moderately adaptable, and modeled as only slightly decreasing in habitat (but still classed as 'No change'). As such, it is rated as a fair capability to cope with the changing climate. This is different from the previous atlas which showed a more severe reduction in habitat. SHIFT shows moderate infill.
Family: Betulaceae
Guild: opportunistic, short-lived intolerant
Functional Lifeform: medium-size deciduous tree
