All-Inclusive List of Electronic Theses and Dissertations

Disturbances have a strong impact on tree stand dynamics across the world. In North America, the larch sawfly (Pristiphora erichsonii) and larch casebearer (Cleophora laricella) are two non-native species of insects affecting tamarack across much of their native range. The majority of research on the effects of larch sawfly on tamarack (Larix laricina) has been conducted in Canada with very little dendrochronological work in the United States along the geographical boundary of tamarack or on the effects of larch casebearer on radial growth. As a consequence, very little is known about the relationship between tamarack and these insects’ outbreaks in …
