Bouleau à papier
Betula papyrifera
Un arbre caduc indigène du Nord à l'emblématique écorce blanche pelant en papier — parmi les plus reconnaissables et les plus photogéniques des arbres tempérés. Originaire des forêts nordiques et boréales ; décline dans les régions méridionales en raison du stress thermique et de la pression du scolyte du bouleau bronze. De courte durée (40-70 ans) comparé à la plupart des arbres canopée indigènes, mais offre une valeur ornementale et écologique exceptionnelle pendant cette période.

Cold hardiness
Future
These values are location-based: this location's current hardiness is the baseline, and the 2050 value is a projected future climate for this same location.

2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Marginal
In plain terms: This location is in Zone 6b today. Its hardiness profile is cold winters, and coldest nights are typically around -3°F. By 2050, the projected hardiness zone is Zone 7a based on SSP3-7.0 (regional rivalry). That is a +0.5-zone shift from Zone 6b to Zone 7a by 2050.
✓→⚠
Well-suited today, but likely marginal by 2050.
Heat tolerance
Future
Heat tolerance values are location-based too: heat days today are observed at this site, and the 2050 value projects this same location under a future climate.
