The latest issue of Kelseya (journal of the Montana Native Plant Society, spring 2017) has a report on our activities at the Milton Ranch in eastern Montana, "Exploring Mosses and Lichens in Musselshell County" by Andrea Pipp. Andrea organized a great event for us in an ecosystem that was unfamiliar to many of us but rich in lichens.
Eventually this issue will be freely available at the MNPS website:
