Leaf litter quality is a stronger driver of decomposition in lawns than the microclimatic effect of trees

René Guénon
Lawns and wooded areas dominate urban green spaces (UGSs) and are known to store substantial amounts of carbon in soils, yet the role of lawn trees in litter decomposition dynamics remains poorly understood. This study assessed how trees influence litter decomposition through (i) microclimatic (temperature and moisture) and (ii) soil properties effects. Decomposition rates of 8 tree and shrub litters (Quercus robur, Quercus rubra, Fagus sylvatica, Platanus × acerifolia, Pinus radiata, Tilia × eu
