When do white birch (Betula papyrifera, aka paper birch) transition from their young (reddish, coppery-colored) bark, to their mature (white, exfoliating) bark? There are some times when it’s fun and interesting to talk about “why” they happen, and I also want to talk about just how cool it is that things happen — period. In this case, I don’t know if there is some rule of thumb about when or why white birches change from their immature bark to their more mature, characteristic bark — all I know

How can you tell gray birch (Betula populifolia) from white/paper birch (Betula papyrifera)? After sharing my video about the ecology of gray birch from this weekend, a lot of people asked me about how to tell the difference between white birch and gray birch. Fortunately, I had enough footage to create an additional video about just that! Enjoy! #tree #trees #birch | Ethan Tapper

Paper birch (Betula papyrifera) is an incredibly important pioneer species in the Northern US and boreal forest of North America. Here we briefly discuss its identification. Soon, we’ll go much deeper! . #tree #trees #plant #plants #botany #garden #gardening #Forest #forestry #arborist #dendrology #horticulture | Levitreeschool
