    Hi all-

    The 2016 SO BE FREE has just been announced.  I posted the flyer on the NWL Facebook page.  We are hoping for a great turnout -- this is the first year it is being organized through the newly created Bryophyte Chapter of the CNPS.  It does not overlap this time with the NWL annual spring meeting!

    Daphne Stone is presenting a free Introduction to Lichens at the Straub Environmental Learning Center, 1320 A Street, Salem on 31 October from 9-4ish.

    We will discuss lichen terminology, then head to a nearby park to look at lichens in their environment.

    Foliose Physciaceae with Dr. Theodore Esslinger

    Location: Oregon Institute of Technology, Klamath Falls, Oregon

    Date: April 1-3, 2016

    Cost: $200

    We are delighted to welcome Dr. Theodore Esslinger from North Dakota to provide us with insight into a diverse and important group of lichens, Physciaceae. The workshop will focus on identification of temperate and northern species in the most frequently encountered foliose genera of the Physciaceae, especially Phaeophyscia, Physcia, Physciella, and Physconia as well as rarer genera such as Anaptychia and Heterodermia.  The first day participants will make observations of Physciaceae in nearby Lava Beds N. M. and then spend the rest of the time working with materials in lab, with most lecturing being informal and occurring while working on the collections.  Among other activities, we will practice the appropriate use of reagent spot tests on the thallus and methods for making hand sections to study the various tissue types of the physcioid thallus.  In addition to material we are able to collect on our field trips students are strongly encouraged to bring specimens with them, especially any problem materials they would like help with.  

    Space is limited; if you are interested in attending please contact John Villella,

    If you would like to discuss changes to the status of particular lichen species on the Oregon Rare, Threatened and Endangered list, as sponsored by ORBIC, you are welcome to join us from 2:30-5 pm on Friday, October 9, and the H. J. Andrews Experimental Forest.

    Note that this immediately precedes the NWL certification (see the Certification tab and Events). BUT you need not be registered for the certification or training to participate in the discussion. If, however, you plan to spend the night at the Andrews forest and are not registered, please let Daphne Stone know (daphstone at gmail).

    If you do plan to participate in the discussion, please bring your data and your ideas.

    Lichens are a vital yet overlooked part of the ecology in our urban areas. 

    Dr. Katherine Glew will introduce lichens, explain what they are and how they grow.  She will also address common lichens found in Seattle and provide a list. You will find out what their presence in the city tells us about your plants and air quality. Bring your hand lens if you have one, since there will be plenty of lichens to find. We will spend part of the day in Washington Park Arboretum, University of Washington Botanical Garden. To Study lichens in more detail, we will have an opportunity to use microscopes to see their fascinating details.

    Katherine Glew has researched lichens in Norway, the Russian Far East, and throughout Washington State.  

    Date: Saturday, June 20

    Time: 9:00am - 4pm

    Location: Washington Park Arboretum and Hitchcock Hall, University of Washington campus.

    Tuition:  $95

  • 28 Mar 2015 2:16 PM | Katherine Glew
    Dr. Katherine Glew will lead a lichen tour in the Cedar River Watershed, east of Seattle to introduce the fascinating lichens of the forest. If you have wondered about what a lichen is and why they are in the forest, this will be a great opportunity to view the lichen diversity in the watershed and learn the names of our most common species. There will be a short classroom session, followed by visits in the watershed, identifying and studying specimens collected from various forest habitats.

    Date: Sunday, June 14

    Time: 10am to 3pm

    Bring: a and lens and a few paper bags for collecting

    Cost:  $20

    This summer, the Eagle Hill Institute (Steuben, Maine) is offering several one week-long workshops that may be of interest to your group (see below). Eagle Hill field courses are of special interest because they focus on the natural history of one of North America’s most spectacular and pristine natural areas, the coast of eastern Maine from Acadia National Park to Petit Manan National Wildlife Refuge and beyond. Our summer field courses are taught by experts in their respective fields. Course participants include beginning to advanced amateurs, graduate and undergraduate students, teachers, professional field biologists, university professors, and personnel from federal and state agencies and numerous environmental organizations.
