Annual Meeting

The 2018 ABLS annual meeting will be at the University of Colorado Mountain Research Station

12-16 August. 

2018 will prove to be a special year for ABLS as we will have our stand-alone meeting at the Mountain Research Station (MRS), University of Colorado, Nederland, Colorado organized by Erin Tripp. The MRS is about an hour west of Boulder.

March 27 - 30, 2017
Near Sequoia National Park, in the Sierra Nevada of California  
The 2017 SO BE FREE bryophyte foray will be held March 27-30, 2017, in the lower elevations of the Sierra Nevada, near Sequoia National Park.  Participants will see a variety of spectacular habitats that are very rich in bryophytes, including the foothills where the valley fog hits the rock outcrops and oak savannahs. The geology includes marble as well as granitics. Depending on snowpack, we may be able to go to the giant sequoia forests.  This is also the annual meeting of the Bryophyte Chapter of the California Native Plant Society.  Registration Deadline is Dec. 15, 2016.  Further details and registration information are given here:

Crum and Tuckerman Workshops

Crum Workshop

May 27-June 1, 2018

Asheville, North Carolina


Registration for Crum 2018 to be held in the Southern Appalachian Mountains of Western North Carolina is now open. We are hoping you will join us at Montreat Conference Center (MCC) Sunday through Friday May 27 – June 1, arriving Sunday afternoon or evening and leaving Friday morning. We are pleased to have secured this site, particularly since it comes with several thousand acres of protected land with miles of trails that we will be able to include in our bryophyte collection plans. You can get a lot of general information on the MCC website at


REGISTRATION PROCESS: MCC has set up a dedicated registration page for us at Most of us will be registering for a lodging + meals package, but there is also a commuter meals package option if you have plans to stay off site. There are more details on the registration page, and you can contact them with questions or we can help you work things out. We hope that most attendees will be able to be there the whole time, but you do have the option of registering for part of it if you can’t make the whole week.


MEALS: Meals are buffet style, and there are more details on the website. There are fairly narrow time windows to show up for meals, but within that timeframe, meals should be quick and easy. Vegetarians, we were assured that there are always options for you included in the buffets, but if you prefer your bag lunches for collection days to be vegetarian, you must indicate this in the comments field when you register.


ROOMS and EQUIPMENT: We will be staying and eating in the Assembly Inn. It is a brief walk across to the Walkup Building which we have reserved as our lab space. We assume that most of you will be driving and bringing your own scopes, books, etc., but if you are flying and need us to round up extra scopes, let us know ASAP so we can work on this.


COLLECTION SITES:  Plans are not finalized, but besides using the Montreat site (acid coves, oak and mixed hardwood forests), we are working on Mount Mitchell State Park (high elevation spruce-fir forest), the Craggy and upper Big Ivy areas along the Blue Ridge Parkway (high elevation mixed hardwood), the Pink Beds (wetland), and Newberry Creek Gorge. We need to keep in mind that access to high elevation areas is not assured even in late May.


Please register soon. We look forward to hosting you.

Tuckerman Workshop

Laurel Highlands of southern Pennsylvania ...  26 April - 1  May 2018. 

From Organizers

"Tuckerman Announcement – Spring 2018

Hello everyone, it’s that time of year again.  We are pleased to announce that registration for the 2018 Tuckerman Workshop is now open. This year it will be held in the Laurel Highlands of southern Pennsylvania, with potential forays into adjacent western Maryland the panhandle of West Virginia. We look forward to seeing you there. This workshop aims to build on modern lichen inventory data already collected from many nearby areas of Pennsylvania. The details are outlined below. Please feel free to e-mail James ( with any questions.

Dates: to Tuesday May 1st. Thursday (26th) will be the arrival/set-up day. Tuesday (1st) will be the day of departure. That leaves four full days of field and lab time.

Meeting venue: The meeting space will be The Barn at Fallingwater (, a property run by the Western Pennsylvania Conservancy. Scott Schuette has generously arranged this space, and many of the other details, for us.

Registration for Tuckerman Workshop: To register fill out and submit this electronic form ( If you encounter any difficulties please contact James Lendemer (

Accommodations: There are several options for accommodations. See below:

1) RUSTIC ACCOMMODATIONS: The majority of participants will likely stay at Ohiopyle State Park ( which is very short drive from the The Barn where we will have our lab. I (James) have stayed in numerous PA State Park cabins over the years and always found them to be clean, perfectly reasonable, and easily used for cooking etc. The only drawback to be aware of is that restrooms/showers are shared use in these facilities and not physically located in the cabins/yurts.
For details about Pennsylvania State Park camping cabins see (

RATES: The total cost for renting a yurt/cabin is ~$200 total for the entire workshop. The exact price varies slightly, but reservations must be made by one person ONLINE or via PHONE. You are welcome to share a yurt/cabin with as many participants as you like. Two people per unit would be ~$100 per person, and four people per unit would be ~50$ per person.

NON-STUDENTS: There are currently four yurts available at Ohiopyle State Park, as well as one cabin (#237). Each yurt/cabin sleeps a maximum of 5, but we recommend booking 2-4 per unit depending whether someone is willing to sleep in a bunk.  If you wish to stay at Ohiopyle, I would STRONGLY urge you to make a reservation for one of these ASAP as they are available to the public on a first-come-first-serve basis.

STUDENTS: We have reserved a block of cabins, the cost of which will be covered by a National Science Foundation grant. When you register, please indicate your status as a student and whether you know another participant already whom you wish to share a cabin with. The exact arrangements for the cabins will ultimately depend on the number of student participants.

2) ACCOMMODATIONS WITH FRILLS: If you wish to have a room to yourself, or otherwise to have accommodations that go beyond those outlined above there are a number of options in Ohiopyle listed on the Laurel Highlands website:

There are also two motels/hotels located in nearby Donegal, PA. These are a ~30 min drive from the laboratory, and the rates are fairly standard for what you would expect at these chains.

Food: As is usually the case, snacks will be provided in the lab, however MEALS ARE NOT INCLUDED. If you are staying at Ohiopyle State Park then your accommodations should have a rustic, but complete kitchen that includes a stove, microwave, and refrigerator (BUT NOT indoor water).

What to bring: Yourself, your microscopes, your lab supplies (as needed), extension cords and surge protectors, literature, and collecting gear. IF YOU ARE DRIVING, PLEASE BRING YOUR MICROSCOPE/S WITH YOU.

What will be provided to workshop participants: With any luck we will have a new set of keys to go along with new comprehensive checklist of Pennsylvania lichens. Bring your favored literature with you, however we will have a small “lending” library of keys etc. that participants will be able to use for reference. Standard spot test reagents (K, C, P, UV) will be available. Limited additional microscope supplies (coverslips, slides, etc.) will also be available. We encourage those who are driving to bring some spare supplies in the event that some traveling from further afield are unable to do so.

What kind of weather to be prepared for: It will likely be cool in the Cumberland Mountains at this time of year. If you don’t like the weather, spend more time at the scopes.

What kind of sites will we visit: The Cumberland Mountains/Laurel Highlands are known for hosting disjunct northern species, as well as unusual assemblages of species from the central Appalachians. There will be lots of hardwoods, but also expect a diversity of rocks ranging from calcareous to non-calcareous.

We look forward to seeing you in the Laurel Highlands!
