    Wykhuis, Aaron, author, Ex, Seth, advisor, Fornwalt, Paula, advisor, Sibold, Jason, committee memberColorado State University. Libraries2022

    Following the mountain pine beetle (MPB) outbreak in the early 2000s in the southern Rocky Mountains, questions remain about what the structure and composition of lodgepole pine forests will look like as they recover. I used Forest Inventory and Analysis data collected by the US Department of …

  12. Management decision-making tools for mountain pine beetle (Dendroctonus ponderosae) (Coleoptera: Scolytidae) populations in lodgepole pine (Pinus contorta) stands

    Bentz, Barbara JoanVirginia Tech1991

    To prevent the buildup of epidemic level mountain pine beetle populations, conditions of the stand environment they inhabit must be altered. Silvicultural treatment is the most effective means for doing this. Preventative treatments work best when applied while mountain pine beetle populations are …
