Foresters love terminology. In fact, foresters have a long history coining detailed words to describe their forest management, dating back to Germany where many terms were developed to describe regional silvicultural systems and methods. It’s no wonder that as foresters we still come across silviculture terms that make us say “hmmm, what exactly does that mean.” Today we are going to talk with Professor Tony D’Amato from the University of Vermont about one such term that we are hearing mentioned a lot these days… irregular shelterwood. This regeneration method is becoming popular in many forest types to develop diverse forest composition and structure. But how do we define and implement a method that is, well, irregular?
