Outdoor seating, a common feature in urban and suburban areas, may have unintended consequences on local ecosystems—particularly for microscopic organisms like tardigrades. These resilient "water bears" thrive in moist environments, often inhabiting moss, lichen, and soil. The introduction of benches, tables, and other seating structures can disrupt their microhabitats by altering moisture levels, shading patterns, and soil compaction.
Research suggests that artificial structures like wooden or metal seating may create new microenvironments, either benefiting or harming tardigrades. For instance, shaded areas under benches could retain moisture, supporting tardigrade survival, while heat-absorbing materials like metal might desiccate nearby soil. Additionally, increased human foot traffic around seating areas may compact soil, reducing air pockets essential for tardigrade mobility.
Urban planners and ecologists are beginning to consider these subtle impacts when designing public spaces. By selecting materials that mimic natural conditions or incorporating green infrastructure (e.g., living benches with integrated moss), it’s possible to minimize negative effects on tardigrades and other microfauna. Understanding these interactions highlights the importance of balancing human convenience with biodiversity conservation—even at the microscopic level.
