Abstract

fetched live from OpenAlex

ABSTRACT Mountain pine beetle (MPB) infestation and salvage logging create a post‐disturbance landscape composed of a patchwork of alive, dead, and clearcut forest stands. Subsequent impacts on runoff generation in snowmelt‐dominated hydrological regimes are largely a function of the proportion of landscape covered by each stand type, but basic information on snow accumulation variations between stand types following beetle infestation is lacking. This study examines snow accumulation in the post‐disturbance landscape of northern interior British Columbia, Canada, to quantify the effects of MPB‐related forest cover change. Field measurements collected in a live and a dead coniferous plot during the 2007 and 2008 winters are compared with those collected in a clearcut (canopy‐free control) to identify inter‐plot differences in snow depth, density, and water equivalent. Interannual variability in snow density and water equivalent is significantly affected by interannual variability in meteorological conditions. In high snow years, the dead and alive plots behave similarly due to the ability of large snowfalls to exceed the interception capacity of the canopy. In low‐to‐average snow years, however, distinct differences in snow accumulation between the dead and alive plots are observed. These are largely due to the canopy structure in the dead plot, which differs significantly from that in the healthy plot largely due to defoliation (needle drop) and the loss of fine branches and stems following beetle infestation. Research results provide key process information for modelling studies examining the effects of these changes on runoff generation at the watershed scale. Copyright © 2011 John Wiley & Sons, Ltd.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
