Evira announces new deployment areas for bred pine seeds and seedlings
The Finnish Food Safety Authority Evira has published new deployment area maps that will be used in the marketing of pine seeds and seedlings from spring 2017 onwards. Bred forest reproductive material provides the best yield in the deployment area determined as most suitable for it. Account has been taken of global warming forecasts in the preparation of the maps.
The new deployment areas are based on research by the Natural Resources Institute Finland (LUKE). The deployment areas are based on models jointly created by Finnish and Swedish researchers, predicting the survival of seedlings in the current climate and tree growth in a climate that is warmer than now.
The borders of the new deployment areas are now more aligned with the latitudes, while they were previously based only on the thermal times of the growth period. In Southern and Central Finland, the deployment areas moved around 50 kilometres to the north due to global warming forecasts. The deployment areas in Northern Finland changed slightly more. In the eastern parts of Northern Finland in particular, they moved clearly to the north from their current position.
Evira has confirmed the deployment areas of all pine seed orchards it has registered, of which there are 102 in Finland. The best individual trees have been selected for the seed orchards from natural forests and cross-bred to produce seeds with excellent genetic qualities. Bred materials can increase the forest yield by 10 to 25 per cent.
In Finland, forest tree nurseries grow around 50 million pine seedlings each year. Plenty of seeds collected from pine seed orchards are also used in forest regeneration, by sowing.
New deployment areas have a two-year transition period
In the trade of forest reproductive materials, the new deployment areas will come into effect immediately. However, the old deployment areas can be used in seed and seedling trade until the end of 2019.
