Betula glandulosa

It seems like the prehistoric plant series was well-received while I was on vacation; on behalf of Alexis, thank you for the comments and emails.

My trip to Jasper National Park a couple weeks ago didn’t quite meet my hopes for autumn colour. It seems like heavy winds had already hit some of the trees and shrubs, so plants ranged from fully-defoliated to still-green, with not a lot in the middle (much of what had turned had abscised with the winds). Still some pleasant pockets of colour, but it would have been a more showy display of yellows and oranges had I arrived a few days earlier.

On the other hand, there was a different set of colours to be found with the dwarf (or bog) birches. I now wish I had spent more time making photographs like the vertical one, as I like the effect of the out-of-focus leaves in the background. Fortunately for me, Betula glandulosa is widely distributed in western and northern North America (including much of British Columbia), so I needn’t travel as far for such images in the future.

Also present in this less-frequented area of the park were numerous ungulate hoofprints. I presume these were moose, as Betula glandulosa is the preferred browse plant of a moose’s summer forage diet in Jasper National Park. In the winter, the buds are eaten by ptarmigan and grouse. Important to keep in mind for next time, it seems that in the central Canadian Arctic, “Grizzly bears…constructed their dens under bog birch cover more than any other plant species. Bog birch was present at 84% of 52 den sites, and it was the highest in percent cover around den entrances. Bog birch roots formed ceilings of several dens studied”. I imagine these would more typically be found in rocky slope areas as opposed to the more boggy region where today’s photographs were taken. On the topic of animals and plants, I think perhaps that will be the next BPotD series, so if you have photographs of a mammal using a plant in some way (food, shelter, etc.) with both the mammal and plant identified, send me a note.

Additional photographs of Betula glandulosa are available via the Flora of the Canadian Arctic Archipelago (follow links at bottom of page).

    Hello Daniel:
    I very much enjoy your work and that of your fellow contributors from around the world.
    I would like to share or forward some of these spectacular plants/trees and their stories to my friends in Ontario and Quebec.
    I am not on Facebook, Twitter, Stumble Upon, GoogleBookmark or the Delicious site and hopefully never will be. Your old site used to have a place that I could check and the photo et al would be forwarded where it was meant to go. Am I missing something on the website or am I just so completely computer illterate that “I know not what I do?”
    Any help would be appreciated.
    Thank you,
    Anne Bradley

    Anne, I think the easiest thing to do is in your browser menu:
    (Firefox:) File -> Send Link
    (IE:) File -> Send -> Link by Email or Page by Email
    Part of the issue with the forward to friend feature from a long time ago was that it could be used to send anonymous messages to someone else using my email address…
