42. Exercise 2: Stand-level marking Instructor note: The following slides give brief overview information and images of some common silvicultural approaches. Given the length of the slideshow, it’s probably best to only show the one(s) that apply to the types in which exercise 2 will take place. For instance, if they’ll be marking a shelterwood treatment, discuss shelterwood. If they’re marking a thinning, discuss thinnings. But reviewing them all may take more time than it’s worth.
This full-day, classroom and field workshop will present key principles of marking timber for harvest in Minnesota in a practical, straightforward format. Participants will learn to weigh costs vs. benefits of marking timber, then mark a stand based on a silvicultural prescription and specific tree selection criteria. At the end of the workshop, you will: Be familiar with common terminology and concepts related to marking timber Have visited a marked site with the forester who marked it, and discussed the marking process on that site Have costs and benefits associated with marking timber Have marked trees based on given landowner objectives and two different silvicultural systems Feel more confident communicating with landowners, foresters, and other loggers about marking timber
