Presentation developed for a Minnesota Logger Education Program workshop in August 2007.
![[object Object],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. The slideshow is somewhat complex. In order to deliver it 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] .](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Hinweis der Redaktion
- This full-day, classroom and field workshop will present key principles of successful Minnesota TSI operations in a practical, straightforward format. Participants will learn to quickly evaluate a new stand’s potential for a TSI treatment, including silvicultural, operational, and economic considerations. At the end of the workshop, you will: Be familiar with common terminology and concepts related to timber stand improvement Have experience designing a hypothetical TSI treatment in two different stands (ideally one conifer, one hardwood, but dependent on site conditions) Have discussed tradeoffs inherent in TSI planning and implementation Have considered and discussed ways that their particular companies might be able to integrate TSI into their operations. Feel more confident communicating with landowners, foresters, and other loggers about TSI.
