[expand]Different trees provided bark with distinctive characteristics:
The birch bark was premier material—the white flexible sheets peeled easily in large sections, the natural oils made bark water-resistant and decay-proof, the workability allowed creating various objects from simple to complex. The birch was optimal bark source for finest work.
The linden bark provided bast fiber—the inner bark yielded strong cordage and textiles, the fiber extraction required processing removing outer layers, the linden products served different functions than birch bark sheets. The linden was fiber source rather than sheet material.
The pine bark was thick and durable—the rough bark provided roofing material and crude containers, the abundance made pine bark available where birch was scarce, the utility was more limited than birch but still valuable. The pine was secondary bark source.
The oak bark contained tannins—the chemical content made oak bark valuable for leather tanning, the industrial use was different from craft applications, the dual utility increased oak’s resource value. The oak was specialized chemical resource.
The elm bark yielded cordage—the inner bark fibers created ropes and bindings, the strength was adequate for many purposes, the processing was similar to linden bark extraction. The elm was alternative fiber source.
