Here, we used laboratory microcosms to test whether the chemical properties of Rhododendron ponticum litter, an invasive shrub in Britain, lead to slower decomposition than that of native (or naturalised) species with labile litter (Acer pseudoplatanus and Fraxinus excelsior), but not relative to the recalcitrant litter of Quercus petraea. Rhododendron Ponticum is part of the vast Ericaceae family. Its native range is across Turkey, Lebanon, Bulgaria, the Caucasus, Spain and Portugal. The species has two disjunct populations one in the southwestern Iberian Peninsula (central and southern Portugal and southwestern Spain) and the other near the southern Black Sea Basin (eastern Bulgaria, northern Turkey, Georgia, and Northern Caucasus).
