This western hemlock is punctated with Red-breasted Sapsucker holes from top to bottom (50-60 feet of holes). It's in a park where I worked a decade ago. Back then, it was only mildly perforated, but enough that animals besides sapsuckers visited the sap wells. I remember seeing Mourning Cloak Butterflies and Ruby-crowned Kinglets enjoying the goo--in the kinglets' case, probably the bugs stuck in it.
Ramshackle and decrepit, yet still a fundamental part of things.
This is a dead Red Alder. It is falling apart beautifully, dropping large sheets of bark. The loose-hanging sheets make for great day-roosts for bats. And the whole thing must be crawling with bugs and other inverts. Nice.
