Fig.4. Fire-damaged forest in Heilongjiang Province: The fire effects were extremely destructive in many places because large-sized plantations (young age classes) on former clearcuts carried the fire quickly over long distances. There were little to none mature and fire-tolerant trees left after clearcut, thus the survival rate and regeneration potential were extremely low in these sites. Photo: GFMC

Fig.5.  The forest landscape of the mountain-boreal forest of the Daxinganling mountains, Heilongjiang Province, is characterized by a fire mosaic of different post-fire regeneration/succession stages and a mix of pioneer species (softwoods like birch and aspen) and conifers (larch, pine).

Fig.6. Recurrent low- to medium intensity surface fires inside of larch (Larix gmelinii) and pine (Pinus sylvestris var. mongolica) stands often kill the fire-susceptible hardwoods which resprout after fire. The mature and fire-resistant pines easily survive surface fires. Photo: GFMC

The lower photo shows a tree stump measured in the field, showing also several fire scars which allow dating of historic fire events. Photo: GFMC, with support by Xueying Di and Tobias Zorn.

Fig.10.  Fire-susceptible tree species such as spruce (Picea jezoensis, P.abies var. obovata, P. koraiensis) are not common in places regularly affected by natural and human-caused wildfires. They survive only in non-flammable refugia, e.g. on rock terrain. Photo: GFMC.
