Were animals without backbones more abundant and varied in campus areas with fallen leaves than in cleared areas?

Details

Fallen leaves provide habitat with moisture and temperature conditions that help some organisms survive winter. Researchers sampled invertebrates at a suburban college campus, comparing areas where leaves had accumulated with areas where they had been cleared. Both abundance and diversity were higher where leaves had accumulated.

Researchers also surveyed students, staff, and faculty about grounds management. Respondents saw moderate benefits for campus safety and appearance, but did not agree that the practices benefited campus ecosystem health. These were opinions, not direct measurements of safety or ecosystem health.

The authors interpreted the survey and sampling results together as suggesting a disconnect between community perspectives and management practices, and proposed changes to those practices. The abstract does not report the size of the differences, detailed sampling methods, or statistical uncertainty. The findings describe this campus comparison rather than establish what would happen on every lawn.
