ParticipantCan anyone comment on how they think through leaving or creating snags. Number, location type of trees?

ParticipantTim,
In the Rockies, I try to leave a minimum of 3-5 larger diameter snags per acre for cavity nesters and others. Often, I’ll have to leave a few more anticipating that once I open a stand up I am going to lose a few to windthrow. They really need to be a minimum of 10-12″ diameter to make a decent snag. Bigger is better.
I have found that girdling trees to create snages is a mixed bag. Out here the wind blows so hard that often those girdled trees will snap off at the kerf. My preferred method to create a snag is to make a decent slash pile at its base and then torch it…
October 24, 2011 at 3:14 pm #69868ParticipantThanks, Scott. I have reasons for leaving snags that are mostly related to access, proximity to skid trails, poison ivy hazards, etc., but not really based on knowledge of forest ecology. Maybe I can improve in that area.
