LARCHWOOD-FUR (Picea ajanensisЧLarix spp) FORESTS

    In Primorye, there are two groups of mixed larchwood-fur forests of different origin.
 A group of native larchwood-fur forests existing indefinitely long would form in the belt of topological and ecological contact of fur and larhwood forests. A most common example would be transitional belts from drained habitats occupied by fur forests to bogged sites occupied by larchwood forests. All versions of correlation of basic forest-forming species, from fur trees with admixture of larchwood to larchwood trees with single dwarf fur trees, are observed in such belts.
    These forests occupy small areas on extensive river valley sites in gradual transition from drained to bogged habitats, and also o mountain plateaus, where they surround bogged larchwood forests occupying depressions in the plateau central areas. The position of these forests in the classification system would correspond to a subformation. Larchwood-fur forests that formed in sites of burned spruce-fur and other forests occupy considerably larger areas. By occupying the habitats of various forest types, such post-fire larchwood-fur forests acquire many similar features within the underbrush and the grass cover, even though a small part of the lower tiers of native forests may be retained in fire-producing tree stocks.
     Most of these forests represent different-duration-restored replacements of spruce-fur forests.
