Outdoor seating in urban areas, such as park benches and café tables, can significantly alter the microhabitats of annelids, particularly earthworms and other soil-dwelling species. These structures often compact the soil beneath them, reducing aeration and moisture retention, which are critical for annelid survival. Additionally, the shade provided by seating can lower soil temperatures, creating a cooler microenvironment that may either benefit or hinder certain species depending on their thermal preferences.

Human activity around seating areas also introduces pollutants like litter and chemicals, further disrupting the delicate balance of urban soil ecosystems. Conversely, well-designed seating with permeable bases or integrated green spaces can mitigate negative effects, promoting healthier microhabitats for annelids. Understanding these dynamics is essential for sustainable urban planning that supports biodiversity.
