Jungle blanket

Anything that sits still in the rainforest ends up with a green quilt.

Moss on a burl.

I've been struggling to learn to identify the many mosses in our forests, with limited success. I think this may possibly be electrified cat's tail moss, Rhytidiadelphus triquetrus. I could be wrong, of course.

Species name referring to the triangular leaves and the occasional three-rowed arrangement of the uppermost leaves of some stems. ... Commonly called the rough neck moss or shaggy moss because of the untidy leaves at the shoot tips. A whimsical name, electri­fied cat tail moss, has gained some popularity in British Columbia.
Distinguishing characteristics:
The very coarse, pale yellow-green plants with usually untidy divergent leaves of the main stem tip and upper branches, the strongly pleated, somewhat wrinkled leaves and the two strong midribs serve as useful characters. (E-Flora BC)

Zooming in.

Coarse moss: check.
Triangular, wrinkled, pleated leaves: check.
I couldn't get a clear view of a double midrib.
Divergent leaves at upper stem tip: check.
Yellow-green (spring green): check.
On logs, rocks, and here, a rotting burl: check.

But I still could be mistaken. Moss is as confusing as gulls or mushrooms.

Tall

The forest at Miracle Beach is mostly Douglas-fir, with a mixture of Western hemlock, Sitka spruce, and Big-leaf maple, and the ubiquitous red alder. It is second-growth forest; it has been logged off once, and once(that we know about; we are newcomers in tree years)  ravaged by fire, so most of the trees are relatively young, but a few of the older Douglas-firs are still standing.

These are tall trees; a mature Douglas-fir can be as much as 100 metres high, at least here on the coast. Inland, they are shorter.

In comparison, the Western hemlock grows normally to 50 metres, occasionally to 60.

I took a series of photos of one tree, and stacked them. I don't know how tall these ones are; the trunks are less than one metre in diameter. A normal width for a fully mature tree could be almost 3 metres.

Foreshortened from my viewpoint at its foot.

The trunk of an older Douglas-fir is branch-free for most of its length, with the foliage in a clump at the top. The bark is thick and deeply grooved. Look for the burl towards the bottom on this tree.

Looking  straight up from the same general area.
