Ecological Effects Of Prescribed Burning, Mechanical Cutting, And Post-Treatment Wildfire For Restoration Of Pinus Albicaulis, Enzo Paolo Martelli Moya
Ecological Effects Of Prescribed Burning, Mechanical Cutting, And Post-Treatment Wildfire For Restoration Of Pinus Albicaulis, Enzo Paolo Martelli Moya
Graduate Student Theses, Dissertations, & Professional Papers
The field of ecological restoration is growing rapidly, increasing the need for reliable and generalizable information on the impacts of management interventions aimed to be restorative. Prescribed burning and mechanical cutting have been proposed as primary strategies for restoration. However, there is limited information on their efficacy and effects in subalpine forest types, suggesting that monitoring to inform adaptive management is a priority need. I used data from a 15-year, replicated before-after-control-impact (BACI) study on Pinus albicaulis (whitebark pine) restoration to assess the ecological effects of prescribed burning and mechanical cutting, with and without subsequent unplanned wildfire, as well as …
Demographics And Growth History Of Whitebark Pine On Undisturbed Sites Across The Northern Us Rocky Mountains, Sarah Flanary
Demographics And Growth History Of Whitebark Pine On Undisturbed Sites Across The Northern Us Rocky Mountains, Sarah Flanary
Graduate Student Theses, Dissertations, & Professional Papers
Along with fluctuating precipitation and temperatures in the form of climate change, whitebark pine (Pinus albicaulis) has seen a territory wide increase in mortality leading to a decline in population. While the most direct influences on whitebark pine health and mortality are mountain pine beetle (Dendroctonus ponderosae) outbreaks, fire exclusion policies, and the spread of white pine blister rust (Cronartium ribicola), climate change can impact the intervals and severity of such beetle, rust, and fire disturbances, and may affect the growth and health of whitebark pine directly. The objectives of this study were to identify whitebark pine stands within the …
The Effects Of Seed Source Health On Whitebark Pine Regeneration Density After Wildfire, Signe B. Leirfallom
The Effects Of Seed Source Health On Whitebark Pine Regeneration Density After Wildfire, Signe B. Leirfallom
Graduate Student Theses, Dissertations, & Professional Papers
Whitebark pine (Pinus albicaulis) is declining nearly range-wide largely from mountain pine beetle (Dendroctonus ponderosae) outbreaks and the exotic pathogen Cronartium ribicola, which causes the disease white pine blister rust. With high mortality in cone-bearing whitebark pine, seed production may not be sufficient to support natural regeneration after disturbance such as wildfire. The objective of this study was to examine the relationship between whitebark pine seed source health and whitebark pine regeneration density in adjacent, stand-replacing burns. I sampled regeneration patterns and seed source health and status in 15 burns within six national forests and …
