| Research Abstract |
Forest fragmentation does not only remove carbon stocks of logged forests, but can also erode substantial biomass from remnant forests through elevated tree mortality. We studied tree communities and biomass across eight stands of Japanese temperate forests, fragmented anthropogenically around 1940s, along a gradient of fragment sizes. Analysis of size structure and tree-ring series inferred that smaller fragments lost more biomass due to deaths of large trees soon after the fragmentation events. Afterwards the biomass appeared to have recovered more rapidly with increasing severity of fragmentation. These results suggest that the time required for tree biomass to recover is extended for decades and certainly over half a century.
