Sea of clouds and sunrise timelapse from Oregon, looking east towards the Cascades, with a couple volcanoes peeking up through the mist. Yes this works for me.

Bryoria fremontii “Wila/Black Tree Lichen”

This lichen was a staple food source for about 20 different native groups (mostly Salish) of people here in the eastern PNW. Wila (which is the Secwepemctsín or Shuswap word for this lichen) grows abundantly here in our Ponderosa Pinelands, coating old trees from crown to floor in dangling blackish hair. No other species in the PNW east of the Cascades achieves quite as much biomass as B. fremontii (up to 3000kg per hectare!). Interestingly, like several other species of edible lichen in our region (e.g. Letharia), some regions have populations with high levels of vulpinic acid which is toxic when ingested in large quantities. It can be nearly impossible to tell these two chemotypes apart visually, and yet the vast majority of the tribes that subsisted on these lichens had to make the distinction daily. 

Tweedy’s Lewisia, Lewisiopsis tweedyi. Montiaceae family. 

This plant is the only species in the Lewisiopsis genus. It is a rare plant that is endemic to only three counties in Washington State. It is usually found in rocky areas and on slopes.
