Litter decomposition rates of two grass species along a semi-arid grassland-forest ecocline

► We measure decomposition rates of two grass species along a semi-arid ecocline. ► Increasing elevation was correlated with rate of decomposition. ► Cooler, wetter sites had higher rates of decomposition than hotter, drier. ► Litter quality (C:N and %N) did not affect decomposition rate. ► There was no 'home-field' advantage with regard to decomposition rate.
