No Mow May and Leave The Leaves: The impact of social campaigns on turf quality
Bibliographic record
Abstract
Abstract The No Mow May and Leave The Leaves social media campaigns, both of which advocate for a minimalist approach to turf management in various settings including home lawns, parks, and urban greenspaces, have gained momentum in the public consciousness. No Mow May encourages homeowners and municipalities to refrain from mowing the grass in May, and Leave The Leaves recommends refraining from raking and removing fallen tree leaves in the autumn. The underlying goal is to support biodiversity, particularly pollinators, by either allowing wildflowers to flourish or providing an overwintering habitat for insects and other small creatures. This study examined each of these campaigns and the combination of both on turf quality and weed establishment. By avoiding lawn mowing until June, the unintended consequences were increased weed invasion and decreased turf quality. Regardless of Leaf treatment, flower number did not differ between mowed and unmowed treatments except when counting immediately followed mowing. Thick leaf litter over turf in the winter led to turf death followed by weed invasion. The challenges we observed associated with No Mow May and Leave The Leaves initiatives could be addressed by integrating science‐backed practices and considering regional variations in climate and grass species. This would ensure that both environmental conservation and turf health are considered.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
