Every other year NW Lichenologists meets for certification for macrolichens in the Pacific NW of North America. Two subgroups attend: those wishing for more training and those taking the certification exam. Check out the info here: northwest-lichenologists.wildapricot.org/page-1854192

So cool to see the freshwater mussel habitat model and map by Shiva Torabian from Virginia Natural Heritage Program @ Society for Conservation GIS meeting out of Joe Weber's GIS lab with VADCR

Occasionally, we get to travel to the NW fringes. Recently, the Calif. Lichen Soc. forayed to San Luis Obispo. How could we not want to see that area too? So, here are few specimens from the Los Osos. Our IDs are

Usnea rubicunda
Heterodermia leucomelos
Lecanora caesiorubella

Your input on them?

Found this guy on the way back from our rafting trip through the Owyhee Wilderness. Never had a Wilson's Snipe pose for me before

Visited our daughter down in CalPoly-SLO and had the chance to do some big and little birding, including some California condors (white-tag 86 & red 27) @PinnaclesNP plus this Curlew and willet combo at Morro Rock. Weather was awesome and included two rattlers

Sometimes you just need to sit back and stare at rocks, or at least the exciting things covering them like this one here with Rhizoplaca, Xanthoria, and others. -Seen in Central Oregon over the weekend, along with Umbilicaria phaea and what keys out to be U. krascheninnikovii on nearby rock. #lichen

It was great to hear about the history of Old-growth forests in the PNW from Jerry Franklin, and as an added treat, to see past U.S. Representative Peter DeFazio at the NW Scientific Association meeting on the UOregon campus last week. #nwsa #uoregon #peterdefazio #oldgrowth #northwestscientific

Nothing is more satifying than seeing the intrepid inventory work of a group of lichenologists tracking rare to even common lichens. Here we are on the Oregon coast last week looking for Erioderma, Leioderma, & Sulcaria, as well as a host of Cladonias and others. Pannaria oregonensis is shown.

Sometimes you hit the TRIFECTA-Lichens, rare birds, and old-growth, as the folks from Evergreen State College did during their group talk on lichens and marbled murrelets at the NW Lichenologists/Scientific Assoc. meeting talk Wednesday. Their mentor, Dr Calabria is leading the way. #lichens

AND HOW MUCH DID THIS COST?
After the SpaceX Starship exploded mid-air, the FAA halted flights into four Florida airports until 8 PM ET. The advisory affected Miami, Fort Lauderdale, Palm Beach, and Orlando airports. The decision followed debris crashing off Florida's coast after the failed launch

This is not acceptable. This is VERY dangerous.

Rapid Unscheduled disassembly= EXPLOSION!

Air traffic halted in Florida because of space launch debris. Explosion was caught on video in Florida, Bahamas, Jamaica and Turks & Caicos. Who is doing the clean up?

The best way to confront a bully about the misinformation he is spreading is to confront him in front of everyone. Macron just did that.
