  abstract = {{S}oils in urban parks are mainly manmade and called {T}echnosols. {T}hese {T}echnosols are made of backfill with or without a topsoil addition, which may affect both the physicochemical properties of these soils and the success of soil fauna colonization. {T}he effects of these initial soil management conditions on colonization dynamics of {T}echnosols have not been evaluated yet. {T}o fill this gap, we sampled earthworms and ants in 20 {T}echnosols covered by lawn and located in urban parks around {P}aris ({F}rance). {W}e selected {T}echnosols constructed with or without an initial addition of topsoil and distributed along an age gradient since construction ranging from 2 to 64 years. {S}urrounding greening index around {T}echnosols, management practices and physicochemical soil properties have also been recorded. {S}urprisingly, no significant differences were observed in the physicochemical properties of {T}echnosols regardless of the absence/presence of topsoil. {C}ommunities were composed of few ubiquitous species, which could explain the lack of species richness response to any of our variables. {E}arthworm and ant abundances increased significantly along the age gradient only in {T}echnosols with initial addition of topsoil. {I}n {T}echnosols, initial conditions apparently determine in part soil macrofauna. {T}hanks to a close collaboration between scientist and managers, we highlighted that managers should add topsoil during the creation of {T}echnosols in order to sustain abundance of ecosystem engineers and potentially the ecosystem services they provide.},
