Natural forest dynamics in boreal Fennoscandia: a review and classification

Key Points

The aim is to review scientific findings on forest dynamics in natural boreal forests of Fennoscandia.
Conducted a systematic search for studies on forest dynamics in boreal Fennoscandia.
Grouped studies into four types of forest dynamics based on disturbance-succession characteristics.
Total of 43 studies included from various sources, both indexed and non-indexed.
Identified four dynamics: even-aged stand, cohort, patch, and gap dynamics based on disturbance types.
Gap dynamics most commonly found in spruce forests; cohort dynamics prevalent in pine forests.
Unmanaged Fennoscandian forests exhibit more diverse dynamics than previously recognized.

Abstract

The aim here was to review and summarize the findings of scientific studies concerning the types of forest dynamics which occur in natural forests (i.e. forests with negligible human impact) of boreal Fennoscandia. We conducted a systematic search for relevant studies from selected reference databases, using search terms describing the location, structure and processes, and degree of naturalness of the forest. The studies resulting from these searches were supplemented with other known works that were not indexed in the databases. This procedure yielded a total of 43 studies. The studies were grouped into four types of forest dynamics according to the information presented on the characteristics of the native disturbance-succession cycle: 1) even-aged stand dynamics driven by stand-replacing disturbances, 2) cohort dynamics driven by partial disturbances, 3) patch dynamics driven by tree mortality at intermediate scales (> 200 m) and 4) gap dynamics driven by tree mortality at fine scales (22
