timber line

Tree-line and forest-line terminology:
1. timber line (synonyms : the economical or the generative forest-line);
2. physiognomical or vegetative forest-line, i.e. the limit of the closed forest regardless of its reproductive capacity;
3. tree-line proper, i.e. the polar, maritime or altitudinal tree-line;
4. the species-line, i.e. the absolute polar, maritime or altitudinal limit of the tree species in question, as seedling, krummholz, thickets, etc.);
5. historical tree-line (macrofossils and other evidence).
The belt between lines 2 and 5 is the forest-tundra ecotone.
