Questions and answers and small group activity: Spruce-Fir: Comparing Regeneration Methods
Thursday, June 14, 2018, Field Trip
- Long-term U.S. Forest Service Research at the Penobscot Experimental Forest handout by Laura Kenefic
- Acadian Forest Research Ecosystem (AFERP) Silvicultural System: expanding gap group shelterwood (Acadian Femelschlag) or group selection with reserves handout by Robert Seymour
Field trip leaders:
- Mindy Crandall: economics
- Allison Kanoti: Forest health
- Keith Kanoti: Operational considerations including BMPs
- Laura Kenefic: silvics and silviculture
- Amber Roth: Wildlife considerations
- Bob Seymour: silvics and silviculture
Planned field stops:
1.) Unmanaged (reference) stand: Forest type, natural disturbances
2.) Even-aged silviculture: managed (shelterwood) regeneration (C23): Importance of advance regeneration
Even-aged silviculture: unmanaged regeneration (C22): Natural development and Rehabilitation treatments
3.) Even-aged silviculture: density management and production forestry (C23, CTRN): Precommercial thinning and Commercial thinning
Lunch
4) Multi-aged silviculture: reverse-J structure (C 16, 17): Controlling species composition under an overwood; Importance of CWD; Contrast with exploitative repeated diameter-limit cutting (C15)
5) Multi-aged silviculture: area-based structures (AFERP irregular group shelterwood, group selection with reserves)
Wildlife, operations, and forest pest issues (balsam woolly adelgid; spruce budworm; hemlock woolly adelgid; windthrow susceptibility; root rots; spruce beetle; brown spruce longhorned beetle) to be discussed throughout

Comparing regeneration methods assignment
The goal of this assignment is to apply the knowledge gained through today’s presentations and your previous experience in summarizing the strengths and weaknesses of different silvicultural systems for spruce-fir forests.
Form a small group and discuss the questions on this worksheet: Assignment for Spruce-Fir Module: Comparing Regeneration Methods. Fill out and submit one group worksheet (see “Upload your assignment” below) by Thursday morning before the session begins. When naming the file, use at least one last name of a person in your group.
