During the Botany 2025 conference in Palm Springs, California, the American Bryological and Lichenological Society (ABLS) held a field trip to Mount San Jacinto State Park. The field trip began by taking a short bus ride from the convention center to the Palm Springs Aerial Tramway, where about 30 bryophyte and lichen enthusiasts were shuttled up the mountain. After the group split into two at the Long Valley Ranger Station, we explored the Long Valley Discovery Trail, which led onto the Desert View Trail. On the hike, the group encountered, collected, and identified a diverse variety of lichens and bryophytes.
