Abstract
Reach-scale restoration to re-establish habitat integrity is practiced throughout the US. These techniques, while yielding aesthetic enhancement, may not result in ecological improvement. Using a before-after, control-impacted (BACI) sampling design, we evaluated the benthic macroinvertebrate community in two branches of the Codorus Creek, Southeastern PA throughout the course of restoration projects. Reach-scale restoration activities at several sites along both branches have been conducted since 2002. There was no significant change in the benthic macroinvertebrate community associated with reach-scale restoration. Even after the restoration projects were completed, downstream-impacted sites on both branches reflected severe stress with reduced numbers of organisms, low diversity, and impoverished pollution sensitive species. Thus, our results indicate that there were no significant short-term benefits resulting from reach-scale restoration. We recommend that the actions of individuals and organizations concerned with streams focus on watershed-scale conservation and restoration activities.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
