Abstract

fetched live from OpenAlex

Abstract. Woody plant encroachment (WPE) refers to the increase in density, cover, and biomass of trees and shrubs, affecting both the environment and economy. Many regions lack quantification of WPE, and its driving factors remain unclear. Shrub encroachment, involving woody plants up to 1.5 meters tall, is particularly challenging to quantify due to the lower height and coverage of shrubs. Remote sensing can address this by leveraging spectral and structural properties to improve shrub detection. Integrating accurate quantifications of shrub encroachment over time in models with a variety of potential driving factors can shed light on primary encroachment patterns and mechanisms, aiding local management efforts. We present a case study in the Cypress Upland ecoregion of Canada, where we examine the relationship between 22 different topo-edaphic, anthropogenic, and climatic factors, and shrub cover changes from 2011 to 2018.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
