État de la populationTexte officiel évaluation IUCNExpert

Forest survey data indicate that Betula papyrifera is most abundant in Canada.

At its northern geographic limit this species coincides with an average July temperature of 13° C (55° F) isotherm and at its southern geographic limit coincides with an average July temperature of 21° C (70° F) isotherm. It grows with wide variations in the patterns and amounts of annual precipitation from a low of 300 mm (12 in) in Alaska to 1,520 mm (60 in) at high elevations in the Appalachian Mountains.

With increases in temperatures due to climate change, the geographic range of this species would contract from its current southern geographic limits, move further north into northern Canada and increase in elevation in the Appalachian Mountains. The core subpopulations occur in Canada and adjacent Alaska. These subpopulations are predicted to expand as the 13° C average July temperature isotherm moves northward and in elevation. Its subpopulations in the northern United States will contract as the southern range limits move northward with average July temperature of 21° C (70° F) isotherm. Potential changes in precipitation patterns and average annual precipitation amounts may or may not adversely affect subpopulations but those potential changes are unknown.

Description complète des menacesTexte détaillé évaluation IUCNExpert

There are no known threats that are or will adversely affect the sustainability of this species in the foreseeable future. Climate change will extirpate it at its southern distribution but this will be offset with it northern range limits expanding and elevational limits increasing across northern Canada and Alaska. Potential changes in precipitation patterns and average annual precipitation amounts may or may not adversely affect subpopulations of this species but those potential changes are unknown. NatureServe (2013) ranks this species secure (G5), however subpopulations in Colorado and Tennessee are Critically Imperiled, those in Wyoming, Illinois, West Virginia and Virginia are Imperiled and those in Indiana and Nebraska are Vulnerable.
