D. fusca can develop a persistent seed bank, with 48 000 seeds m-2 (0-6 cm depth) measured at one site 18 months after the last seed input. No seedlings emerged from depths >10 mm whereas 60% of seedlings arose from seed lying on the soil surface. Emergence was strongly inhibited by presence of litter or living pasture plants. Highest seedling density was on bare ground (1480 m-2), but this represented <5% of the seed bank. High dormancy levels were found in seed which had been stored dry and exposed to natural weather conditions. Storage in water gave highest germination, but a single drying cycle reduced germination from 44% to 10%. Darkness inhibited germination of non-dormant seed. -from Authors12en198910.2307/24040800024944144
