Marking Timber in Minnesota

Instructor’s note: About this slideshow This slideshow includes somewhat detailed slide notes. The notes convey the key ideas of each slide. This should allow the slideshow to be delivered well by any knowledgeable instructor. Note that several slides include built-in animations. The word [Click] in the notes is the cue to advance to the next animation. In order to deliver the slideshow well, the instructor must be familiar with the sequence of animations and slides. Adequate preparation is important. Like every slideshow, this one is best delivered in the instructor’s own voice, not by reading the notes. The notes should be viewed as a guide, NOT a script . Any questions about this slideshow can be directed to Eli Sagor at [email_address] .

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.

Exercise 2: Stand-level marking
