1.     Mirror Lake. For the field trip to Mirror Lake, please gather at the shore in front of the Hamlets at 3:30 pm. The tour and discussion will focus on long-term water and energy budgets, ecosystem structure and function, biodiversity changes, conservation and climate change. Trip leader: Gene Likens

2. 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 3:30 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, Jeff Garnas, Miranda Zammarelli.

3. Hydropedology and saturation hotspots in the landscape. This trip will leave from the parking area above the USFS Pierce lab by car at 3:30 pm. The trip will last about 2 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 and will only involve a short walk (less than 1/4 mile), but over rocky, uneven terrain. 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 and Angela Possinger

4. 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 3:30 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

5. Streams. This trip will leave from the parking area above the USFS Pierce lab by car at 3:30 pm. We will head up the Hubbard Brook mainstem above the bridge and poke around in the stream. We'll start out by flipping over rocks to look at aquatic insects, and talk about patterns in stream insect emergence that we're starting to see in the sticky trap data. From there we'll talk about...anything you ever wanted to know about a stream. Bring old sneakers, Chacos, or similar footwear if you want to rock hop and get wet, or stand on the drier spots and we'll bring bugs to you. Trip leaders: Chris Solomon, Heili Lowman

6. Forest recovery in Watershed 5. This trip will leave from the parking area above the USFS Pierce lab at 3:30 PM. The trip will last about 2 hours and can accomodate all who are interested. We'll drive to the base of Watershed 5 and hike about 100 m to Met Station #7. We will then transect the Watershed 5 to see how the forest is recovering 40 years after a whole-tree harvest. We will continue our westward transect through Watershed 6, the vegetation reference watershed, to compare the recovering forest to the mature forest. We will discuss constraints on forest recovery (e.g., legacy of acid rain) as well as ongoing threats to the mature forest (e.g, beech bark disease and drought). We can also elaborate on recent improvements in our understanding of tree allometry and discuss the potential impact of an Enhanced Rock Weathering Experiment on forest dynamics in Watershed 5 Trip leaders: John Battles, Charley Driscoll, and Geoff Wilson.
