Epiphytes on Big Leaf Maple

One of the most accessible places to learn mosses and liverworts in the coastal regions of the Pacific Northwest is along the trunk of a big leaf maple (Acer macrophyllum). This tree, on account of the rivulets and ridges that run down it and the dense and dichotomously branched canopy is a haven for thick carpets of bryophytes and a few other epiphytes. Below are photos of the some of the common species you might encounter. I'll try and add more as I encounter them.

Also in the comments below, @chlorophilia mentions a much more in depth repository of Big Leaf Maple epiphytes and associated that can be found here:

This is an excellent post, rambryum. It will make these bryophytes much more interesting and more accessible to people. Would it be all right with you if I share your contribution on the Biodiversity Squamish FB Group Page?

Posted by judithofsquamish almost 4 years ago

By all means. I still need to add about 10 more species of bryophytes and lichens:

Antitrichia curtipendula
Dendroalsia abi..
Isothecium stoloniferum
Orthotrichum lyallii
Plagiomnium venustum
Plagiomnium insigne
Porella navicularis
Zygodon ver.

Graphis scripta
Lobaria pulmonaria
Parmelia sulc.

Thank you for sharing this! I need to pay more attention to those epiphytes now :)

Posted by jkaseman18 almost 4 years ago

Porella cordaeana is another common epiphyte on bigleaf maple

—great note Randal! You remind me that I had set up a project once upon a time toward a similar end!

I had no idea Plagiomnium could grow on a maple! So cool!!

With all the rain this spring, the bryophytes in Squamish are catching the eye of people 'out there' exploring. It's timely to re-post your wonderful journal entry, Randal/rambryum, to the Biodiversity Squamish FB group page, together with the link that Andrew/chlorophilia contributed. Thanks to both of you!
