High-quality seedlings with the right origin, for safe forestry

Any forest-tree seedlings sold must be healthy and meet the quality criteria set for them. Forest trees growing in a certain area are adapted to that particular area’s climate. Hence, using seedlings with the right, local origin will ensure a successful cultivation outcome.

When trees are moved from the South too far to the North, the transferred trees’ growth period will continue longer than that of local trees. The winter cold then surprises such Southern trees too early. Their tissues, unprepared for winter, become damaged, exposing the trees to various types of other damage. Transferring trees too far to a different climate is harmful to tree health. Selecting the right origin is the purchaser’s responsibility.

Bred material is produced in seed orchards

By using bred seed, a forest-owner can achieve a 15–20 per cent growth increase in comparison with seed collected from a forest stand. Bred seed is produced in seed orchards. Evira approves and inspects forest-tree seed orchards and monitors to ensure that the quality criteria set for them are fulfilled. Evira confirms utilisation areas that are suitable for seed and seedlings coming from seed orchards and also monitors the quality of non-bred material.

A seedling’s origin and quality classification are shown in its master certificate and label

All forest-tree seed and seedlings must have a master certificate certifying their origin, issued by Evira. Evira supervises all seed production phases, from the collection of cones or seed to its extraction, purification, packaging, and marketing. Appropriately controlled forest reproductive material must be accompanied with a seedling label bearing the code of the master certificate and other information on the seedlings’ quality and origin. The purchaser should make sure that he or she receives the necessary information from the seedlings’ seller and that the material’s origin is suitable for the target regeneration area. A forest-owner who appreciates sound timber outcome and quality also pays attention to the material’s genetic quality.

Control of production

Production locations and warehouses for forest-tree seed and seedlings are controlled with regular inspections. Control ensures that seed and seedling lots are not mixed with each other during the various production phases. It also verifies that the information provided to the purchaser of forest reproductive material is correct and reliable. In addition, the health and quality of seedlings are controlled.
