1.       The incipient extirpation of ash: is one tree as good as another? This trip will leave from the parking area above the USFS Pierce lab at 2:00 pm. The trip will last about 2 hours, and can accommodate all who are interested. This will be a walking trip, with about 200 m of elevation. Trip leaders: Matt Ayres, Liz Studer, Miranda Zammarelli

2.       The multi-threaded Hubbard Brook - baseline ecosystem state and river restoration by natural dams. This trip will leave from the parking lot below the USFS Pierce lab (near the barn) at 1:30 PM. The trip will last about four hours and can accommodate all who are interested. This will be a walking trip, with approximately 2 miles of moderate walking, with occasional bushwhacking through hobblebush, at the pace of scientists talking in the woods. Trip highlights: beaver dam on Hubbard Brook between Kineo and Split Brooks, charcoal exposed by a tree tip-up, paleochannels, new channels, and other natural dams made variously of logs, sticks, roots, and leaves in the riparian forest. Trip leaders: Denise Burchsted and Scott Bailey (in absentia).

3.       Incoming oaks? What would it take for northern red oak to become a part of canopy in the forest? This trip will leave from the parking area above the USFS Pierce lab at 2:00 pm. The trip will last about 2-3 hours, and can accommodate all who are interested. This will be a walking trip, with about 200 m of elevation. Trip highlights: We are looking for a lively discussion of the many current and expected changes to the forest and some likely future shifts in the trees and understory. We will walk up the Norris Brook path OR walk down Cant Dog Road to the brook. TBD by group. Trip leaders: Nat Cleavitt and Jackie Matthes

4.       Hydropedology and saturation hotspots in the landscape. This trip will leave from the parking area above the USFS Pierce lab by car at 2:00 pm. The trip will last about 3 hours and can accommodate about 16 people based on vehicle limitations. Volunteer drivers to Watershed 3 are required. This will be a walking trip in Watershed 3 with about 200 m of elevation gain and 2 km of hiking round-trip. Trip highlights: Many patterns in ecosystem processes can be explained by accounting for the systematic variation of soils and soil moisture. In this field trip, we will see how the landscape influences soil patterns and processes, and explore interactions between soils, streams, and ecosystem processes. Trip leaders: Kevin McGuire, Jenny Bower, Angela Possinger, and Linda Pardo.

5. Climate Change Across Seasons Experiment (CCASE). This will be a relatively short field trip that involves a short (five-minute) walk from the upper USFS parking lot, leaving at 2:00 PM. In this experiment, our goal is to determine the long-term effects of warming growing seasons and a small winter snowpack and greater frequency of soil freeze/thaw cycles in winter on the functioning of the northern forest. We will share our experimental design and show everyone the enclosure that holds all of our dataloggers and electrical equipment controlling the experiment. We will also show you the experimental plots and explain how we make measurements of trees, soils, microbes, and invertebrates. Trip leader: Pam Templer
