The potential effect of the exotic linden Tilia x euchlora, widely planted in urban greens, on soil-dwelling annelids (Lumbricidae, Enchytraeidae) was investigated in two parks in the city of Brno, Czech Republic. Linden trees are the source of honeydew that might affect soil biota and remains an important input of these trees into the soil compartment even if litter is being removed as part of the park management. There have also been discussions about the alleged toxicity of T. x euchlora nectar to pollinators. The native T. platyphyllos was used as a control. Within two days in November 2006 annelids were sampled at three different distances (1 m, 3 m, 6 m) along transects from the trees to well developed lawns. Earthworms were extracted by the electrical-octet method, enchytraeids by wet funnel extraction from soil cores taken down to 12 cm.
