Pack Forest, March 31 2012
On a class trip to UW experimental forest 'Pack Forest' near Mt. Rainier small groups were led throughout trails in the areas immediately surrounding the facilities provided by UW.
Weather was overcast, mid 50's
The lowland forested area canopy consisted mostly of Douglas fir and Western hemlock, while the understory often consisted of plants such as Salmonberry, Huckleberry, Flowering Red Currant, as well as western sword fern, dull oregon grape, english ivy, pacific trailing blackberry and Salal.
there was an abrupt change in under story plants as the soil changed from wet to dry moving up slope, changing from mostly dense sword fern, and salal to a more shrub dominated environment in drier soil, where more salmon-berry, and Flowering Rec Currant could be seen. The canopy also shifted as we moved up slope, changing to more deciduous trees, such as Red alder and Big Leaf Maple.
many different types of epiphytes grow on the trees here, and unlike in the city, they can grow to be quite large, many of the ones seen are posted on iNaturalist.
my species list includes those attached to this journal as well as;
Schtchbroom
Lodgepole Pine
Cat Tail
Xanthoria (orange lichen)
Hymenoptera-ant hills

Blackberry plant observed growing mid slope, leaves facing southwest, towards open grass field.

Growing in several meter radius patch along an apparent vehicle path. Leaves numerous, with sparse flowering structures; all growing in a very wet, muddy substrate, with open sky above, surrounded by several deciduous trees, as well as some douglas fir, none of which grow within several meters of the patch of coltsfoot, isolated by the road, as well as a drainage ditche paralleling the road adjacent to the patch of coltsfoot.

花旗松 (Pseudotsuga menziesii)觀察者
jjensen描述
many, many Douglas-fir trees were seen at pack forest, and along with some big leaf maple, and some red alder, make up a large part of the canopy at pack forest, especially at wetter, lower elevations. mosses and lichens are common on all trees, and can bee seen here growing on the branches and stem of several Douglas-fir trees.

approx. 7 cm stem to tip, complex but shallow ridges, with thick solid stem. Mushroom was growing among leaf litter on walking/previous driving path in extremely wet soil near drainage ditch. abundance of fruiting bodies was low, and relatively spread out along the trail.
this particular specimen was trampled, but allows a view of the stem underneath the indented outer structure.

地卷菌目 (目 Peltigerales)觀察者
jjensen描述
This foliose lichen was found growing on the mossy surface of a downed tree. It was difficult to even guess at an identity without a guidebook but the closest I could guess at might be "Nephroma."
