framework to reconstruct the post-eruption forest landscape from 1710 to 2010. Results Remnant seed sources’ contribution to basal area and density was minimum before year 1810 and 1770, and increased to maximum at 1940 (51%) and 1840 (79%), respectively. Remnant seed sources contributed [ 40% to stand age from 1740 to 1870. Remnant seed sources’ contribution to species area was minimum at 1760 for all species, while it increased to [ 40% at 2010 for some late-successional species. Conclusions Remnant seed sources have relatively small effects in the early stage of post-volcaniceruption forest landscape recovery. This is different from what has been reported of other disturbances such as wind and fire. Remnant seed sources facilitate late-successional species recovery, advance forest succession, and increase stand age. These findings coincide with reports of other types of disturbances. Spatiotemporal historic landscape reconstruction provides a platform to simulate seed dispersal and quantify the roles of remnant seed sources on postdisturbance landscape recovery.

Abstract Context The rate and trajectory of forest landscape recovery after a volcanic eruption rely largely on available seed sources and patterns of seed dispersal. However, quantifying the importance of various seed sources has not been attempted. Objectives We demonstrate a forest landscape modeling framework for spatiotemporal reconstruction of post-volcanic-eruption forest landscape. We quantify the effects of remnant seed sources on post-eruption forest landscape recovery at tree species level in Changbai Mountain, China. Methods We used a factorial experiment of modeled scenarios with/without remnant seed sources and/or matrix seed sources. We applied the modeling

Introduction Catastrophic disturbances such as volcano eruptions can completely destroy forest ecosystems and restart forest succession. Forest landscape recovery after volcano eruptions relies largely on seed sources and seed dispersal from undisturbed
