Assessing Alternative Methods For Monitoring Populus Tremuloides Following Restoration Treatments, Michael Fowler

Graduate Student Theses, Dissertations, & Professional Papers

A variety of alternative sampling methods, commonly known as “Distance Methods”, were tested to determine if they could be a better choice for monitoring Populus tremuloides (quaking aspen) regeneration following aspen restoration treatments. These methods were evaluated based on their ability to accurately and efficiently estimate three common aspen stand characteristics used to gauge aspen restoration treatment effectiveness: aspen regeneration density, browse pressure, and height class distribution. Distance Method accuracy and efficiency were compared to a standard fixed-radius plot sampling method in four treated aspen stands in western Wyoming. None of the Distance Methods fulfilled all of the requirements, which …
